Key takeaways

Facts in this document are as of 12 October 2026. The main study figures, government evaluations and vendor claims were re-checked against primary sources that day; facts not re-read keep their original read dates.

  • The strongest evidence is in customer support and clinical documentation, not autonomous agents. A field study of 5,179 support agents found 14% more issues resolved per hour (34% for novices). In three ambient-scribe trials, burnout or exhaustion scores improved in every arm, but time savings were smaller and uneven.
  • Gains are real but narrow. BCG consultants were 25.1% faster on tasks inside AI's capability frontier and 19% less likely to be correct on a task outside it. Experienced open-source developers in one trial took about 19% longer with AI while believing they were 20% faster.
  • Most organisations use AI; few have measured a profit. Press coverage of McKinsey's 2026 survey puts the share of respondents reporting any enterprise-level EBIT impact at 37%, about the same as in 2025 (secondary); in Deloitte's 2026 report, 66% report productivity gains but only 20% increased revenue. MIT NANDA's contested headline is that 95% of GenAI pilots showed zero measurable P&L return, with ROI judged six months after the pilot. The authors call their interview-based figures "directionally accurate".
  • Most company figures are self-reported. Vendor pages report wins such as drafting cut from 15 hours to 15 minutes with no baseline or sample. Large banks' primary disclosures are mostly adoption counts or a single time saving.
  • Reversals happen where cost targets came before quality data. Klarna began rehiring human agents in 2025. Commonwealth Bank of Australia reversed 45 voice-bot job cuts after the union argued that call volumes were rising.
  • The first labour effect is fewer entry-level hires. Stanford's August 2026 update puts 22-to-25-year-olds in the most AI-exposed occupations about 19% below expected employment, driven by reduced hiring. India's five largest IT firms shed a net 7,389 staff in FY26, according to secondary reports, with AI one cause among several.
  • What works is plain and measurable: high-volume tasks with checkable results, a baseline before the pilot, a quality metric beside every efficiency metric, and a route to a human.

How to read the evidence in this document

Mixing evidence grades is how most ROI claims go wrong: a randomised trial and a vendor case study can both report a percentage, but the numbers carry very different weight. This document labels every claim with its grade and, where research rounds conflict, uses the primary source and says why. Some primary pages (the World Economic Forum's report, OpenAI's website, several Indian investor sites) blocked access, so figures from them rest on labelled secondary reports.

Label Meaning
Independent trial A randomised or pragmatic trial run by researchers and published as a journal article or working paper
Survey Self-reported answers from organisations or workers
Company-reported A company's statement about its own operations, such as a press release, annual report or executive interview
Vendor-reported An AI vendor's statement about its own product or about a named customer
Secondary A news or aggregator report whose original document was not read

The second distinction is between adoption metrics (users, seats, agents deployed, conversations handled, AI product revenue) and outcome metrics (time per task, cost per contact, error rate, customer satisfaction, revenue or profit). "65,000 staff use our LLM platform" is adoption; "calls are a minute shorter" is an outcome. Most 2026 headline numbers are adoption metrics. Related documents in this set cover adjacent ground: Costs and economics for unit prices, Governance for risk controls, Implementation playbook for delivery method, India for the domestic market and Future outlook for forecasts. Terms are defined in the Glossary.

Customer support and coding lead the function catalogue

Ranked by quality of evidence rather than volume of marketing, customer support is the most mature function in October 2026: it alone has a large field study, large company deployments, published per-outcome prices and two documented reversals, which together show what works and what fails. Software development has the most randomised evidence, but the studies disagree. Clinical documentation has the cleanest independent trials, though mainly for healthcare providers. Every other function rests on vendor-reported cases or none. "Maturity" in the table means maturity of evidence (how sure anyone can be that the use case delivers), not how widely it is sold.

Function Evidence maturity Typical outcome metric Best-documented example (label)
Customer support: agent assist High. Field study plus large company deployments Issues resolved per hour; average handle time; customer sentiment 5,179 agents: +14% issues resolved per hour, +34% for novices (independent study) (NBER w31161). Bank of America's EricaAssist is used by 18,000+ representatives and cuts calls by "nearly one minute" (company-reported) (BofA newsroom)
Customer support: autonomous resolution Medium. Large deployments, but the figures come from vendors and executives, and there are two public reversals End-to-end resolution rate; escalation and repeat-contact rate; cost per resolution Fin agents resolve "on average 76%" of support volume end to end (vendor claim in Salesforce's acquisition release) (Salesforce). Fin's own homepage repeats the 76% "across 12,000+ businesses" (vendor-reported; resolution not defined) (fin.ai). Meesho's voice bot cut some customer call costs by 75% (company claim) (TechCrunch)
Software development Medium, contested. Randomised studies point in different directions Merged pull requests; task time; rework and test coverage 4,867 developers in three field experiments: +26.08% completed tasks (SE 10.3%) (published abstract, Microsoft Research). The authors' slides report 5,114 developers and pooled pull-request gains of about 25% to 31% (provisional) (slides). 16 experienced developers took 19% longer with AI (independent trial) (METR)
Knowledge work and consulting deliverables Medium. One preregistered trial plus a capability benchmark Tasks completed; time taken; graded quality; error rate outside the frontier 758 BCG consultants: 12.2% more tasks and 25.1% faster inside the frontier (HBS)
Clinical documentation Medium-high. Three independent trials Time-in-note; after-hours work; burnout scores Nabla scribe: 9.5% less time-in-note. DAX: no significant change. Both improved burnout scores (PubMed 41497288)
Document drafting (legal, investment memos) Low-medium. Vendor-reported only Drafting time per document; reviewer edit time EvenUp: drafting cut "from 15 hours to 15 minutes" (vendor) (claude.com). Fifth Dimension: memo drafting cut from weeks to 30 minutes (vendor) (Google Cloud)
Internal knowledge assistants and copilots Medium for adoption, low for outcomes Searches answered; self-reported hours saved; active users UK cross-government Microsoft 365 Copilot experiment: about 20,000 staff in 12 organisations, self-reported average saving of 26 minutes a day (government evaluation, self-reported) (GOV.UK). Barclays' colleague assistant: more than 1 million searches by 16,000+ colleagues, no savings published (vendor news page) (Anthropic). Gordon Food Service: "20,000+ hours monthly" saved (vendor) (Google Cloud)
Email and document triage and routing Medium for volume, low for outcomes Items routed per day; routing accuracy; turnaround time Barclays Global Markets classifies and routes about 120,000 client emails a day (vendor news page) (Anthropic)
Finance and accounting (payables, invoices, reconciliation) Low. No verified named case Cost and time per invoice; exception rate No verified quantified case. MIT NANDA reports the largest measured ROI in back-office automation (secondary) (Fortune)
HR and employee service Low. One vendor case Share of requests fully automated Hershey Entertainment & Resorts: "fully automated more than 25%" of staff "call off" requests (vendor) (Google Cloud)
Sales and marketing (content, search, recommendations) Medium for conversion metrics, all vendor-reported Conversion; click-through rate; revenue per search; content cycle time Toolstation: search revenue +5.5%, searches with no results down from 2% to 0.1% (vendor) (Google Cloud). Kraft Heinz: product content in 8 hours instead of 8 weeks (vendor) (Google Cloud)
IT and network operations Low. One vendor case Event-handling time; time to resolve incidents Deutsche Telekom's MINDR multi-agent system: more than 95% reduction in event management times (vendor) (Google Cloud Next '26)
R&D and drug discovery Low. Vendor-reported Cycle time; lab experiments avoided Schrödinger: "70% faster therapeutic drug development" and 97% fewer molecules built in the lab (vendor) (Google Cloud)
Procurement, supply chain, data analysis Very low Cycle time; forecast error No verified quantified case

Where independent researchers measured the work, gains fall between single digits and about a third; where vendors measured it, claims run to 60-fold (15 hours to 15 minutes) with no baseline. The best-evidenced functions share three traits: high volume, a checkable outcome (an issue resolved, a pull request merged, a note written) and a human still in the loop. MIT NANDA, as reported by Fortune, found that more than half of GenAI budgets went to sales and marketing tools while the biggest measured ROI came from back-office automation (Fortune). That finding is secondary, but it points to the same functions the trial evidence favours.

Every industry has pilots, but few have audited numbers

Industry evidence is thinner than function evidence. Most named, quantified examples come from vendor pages (chiefly Google Cloud's customer stories and Cloud Next '26 summary, plus Anthropic's customer pages), which report outcomes on the vendor's definitions with no baseline or sample. The exceptions are healthcare, which has independent trials, and banking, where some companies published primary figures. Where an industry has no verified quantified case, the table says so. Indian cases are marked [India].

Industry Named, quantified example Type of metric Label
Banking and financial services Bank of America: 18,000+ representatives use EricaAssist, calls nearly one minute shorter (BofA).

Zendesk: "1 million agent executions in 7 weeks" (claude.com). CRED [India]: "2x faster feature delivery and 10% better test coverage" (Anthropic) Headcount; volume; developer speed Executive statement (secondary); vendor-reported
Education Duolingo's "AI-first" memo, with no outcome figure Policy only No verified quantified case
Government and public sector UK cross-government Microsoft 365 Copilot experiment (30 Sep–31 Dec 2024): about 20,000 staff in 12 organisations; self-reported average saving of 26 minutes a day; over 70% said it cut time on searching and routine tasks; 82% would not want to go back; adoption about 80% (GOV.UK). HMRC phase 3: 1,364 respondents; self-reported savings of 2–3% of the working week (about 60 minutes), adjusted down by about 20% as a "baseline estimate"; 46% of non-users cited security or privacy (GOV.UK HMRC). The DWP evaluation was not read (GOV.UK DWP) Self-reported time; adoption Government evaluation (primary), self-reported
Energy and utilities; agriculture; media — — No verified quantified case

Two cautions apply when reading these cases. Retail and search cases report the most precise figures (no-result searches down from 2% to 0.1%), but they measure conversion and revenue, not labour automation. And the agent counts (800 at GE Appliances, 300 at Tata Steel) and employee reach (75,000 at Merck) are adoption metrics: they show that deployment is real, not that any agent pays for itself (Google Cloud Next '26). Vendor background is in the Gemini, Claude and Companies documents.

Controlled studies show real gains inside a narrow frontier

Only rigorous studies separate the effect of AI from everything else that changed at the same time. Three findings recur: gains are largest for less experienced workers; they vanish or turn negative outside what the model handles well; and people's own estimates overstate what was measured. Where research rounds conflict, the later primary-source reading is used.

Study Design and sample Finding Limitations
Brynjolfsson, Li & Raymond, "Generative AI at Work" (NBER w31161; QJE 2025) Field study of a GenAI assistant in one firm's customer support; 5,179 agents per the NBER abstract (NBER) +14% issues resolved per hour; +34% for novice and low-skilled agents; minimal effect for the most experienced; better customer sentiment and higher retention One firm, tool and function. Published in the Quarterly Journal of Economics 140(2), pp. 889–942 (2025), per NBER's listing. The QJE article was not readable, so the NBER abstract figures are used
Dell'Acqua, Mollick, Lifshitz-Assaf, Candelon, Lakhani et al., "Navigating the Jagged Technological Frontier" (HBS, with BCG) Preregistered; 758 BCG consultants randomised to no AI, GPT-4, or GPT-4 plus a prompting overview; 18 tasks inside the frontier, one outside (HBS) Inside: 12.2% more tasks, 25.1% faster, significantly higher quality. Outside: 19% less likely to be correct One firm and model generation; the outside result rests on one task
Cui, Demirer, Jaffe, Musolff, Peng & Salz, three field experiments Randomised GitHub Copilot access at Microsoft (1,749 developers), Accenture (311, encouragement design) and Dell (3,054, randomised invitation date); 5,114 in total (slides), up to 14 months (slides). Published abstract: three field experiments at Microsoft, Accenture and an anonymous Fortune 100 company, 4,867 developers (Microsoft Research) Pull requests (two estimation methods): Microsoft +14.8% and +31.9%; Accenture +7.5% and +8.7%; Dell +51.4% (not significant); pooled +24.6% and +30.7% (significant at 1%) The published abstract (primary) reports 4,867 developers and 26.08% more completed tasks (SE 10.3%), with larger gains and higher adoption for less experienced developers. The authors' slides report 5,114 developers and pooled pull-request gains of about 25% to 31% (column mapping provisional; Microsoft alone about +31% with large standard errors; early-career about +55%). The two versions differ in sample, outcome and named sites and are not reconciled. Pull requests are a proxy
METR randomised trial (July 2025) 16 experienced developers, 246 real issues on large open-source repositories they had worked on for years; each issue randomly assigned AI-allowed or not (METR) Tasks took 19% longer with AI (95% CI +2% to +39%, as restated in METR's 2026 post); developers expected 24% faster and afterwards believed 20% faster Small sample, specific setting; early-2025 tools (mainly Cursor with Claude 3.5/3.7 Sonnet)
METR follow-up (post of 24 February 2026) New experiment begun August 2025: 10 returning and 47 newly recruited developers, paid USD 50 an hour against USD 150 in the first study (METR) METR called the signal "unreliable": developers declined to take part, or withheld tasks, rather than work without AI, and timing was hard with several agents running. Raw estimates: 18% less time for returning developers (95% CI −38% to +9%) and 4% less for new recruits (−15% to +9%) Selection effects; both intervals include zero; METR treats the estimates as a likely lower bound and is redesigning the study
NEJM AI, ambient AI scribes randomised trial (December 2025) 238 outpatient physicians in 14 specialties at UCLA, November 2024 to January 2025; covariate-constrained randomisation to DAX, Nabla or control; DAX used in 33.5% of 24,696 visits, Nabla in 29.5% of 23,653 (PubMed 41497288) Nabla −9.5% time-in-note (95% CI −17.2% to −1.8%); DAX −1.7%, not significant; both improved Mini-Z burnout scores (+2.83, +2.69 on a 10–50 scale) Two products, one health system; tools used in about a third of visits; burnout results are secondary end points the authors say need confirmation; clinicians reported occasional clinically significant inaccuracies. Funded by UCLA's Department of Medicine and others, per the abstract
NEJM AI, pragmatic trial on practitioner well-being (December 2025) Stepped-wedge randomised trial, 66 practitioners at University of Wisconsin clinics in two states, over 24 weeks; 71,487 notes, 38% generated with ambient AI (PubMed 41625485) Work exhaustion and disengagement down 0.44 points on a five-point scale; time on notes down 0.36 hours a day (95% CI −0.55 to −0.17); work outside work down 0.50 hours a day, but not significant once the top 3% of daily observations were removed Small practitioner sample, one health system; professional fulfilment did not improve significantly
JAMIA, randomised crossover of two scribes (May 2026) Open-label crossover, 160 outpatient clinicians at one academic centre; surveys from 136 analysed (PubMed 41729180) Both reduced burnout; workflow satisfaction differed by 0.60 points on a 1–7 scale (95% CI 0.32 to 0.90); one product cut note time by 3.19 more minutes a day than the other; after-hours time largely unaffected Volunteer sample; products not named in the abstract; satisfaction self-reported
GDPval (OpenAI; arXiv, 5 October 2025) 1,320 tasks from 44 occupations in the nine largest US GDP sectors; experts averaged 14 years' experience and about 7 hours per task; 220-task gold subset, blind pairwise grading (arXiv; arXiv HTML) 47.6% of Claude Opus 4.1 deliverables rated as good as or better than the expert's; models "approaching industry experts"; losses mostly from instruction-following or formatting failures Capability, not ROI; automated grader agrees with experts 66% of the time against 71% between humans; other win rates not extracted
OSWorld 2.0 (June 2026) arXiv 2606.29537 (submitted 28 Jun 2026, v2 13 Jul 2026): 108 long-horizon workflows, median about 1.6 human hours, about 318 tool calls per task; binary completion within 500 steps (arXiv) Paper: best result Claude Opus 4.8 (max thinking) 20.6% binary (54.8% partial); GPT-5.5 plateaus near 13%. Later leaderboard rows (Epoch's copy of osworld-v2.xlang.ai, secondary): Claude Opus 5 (Max) 31.4% binary / 68.3% partial; GPT-5.6 Sol (Max) 27.3% / 62.7%; no Opus 5.5, Fable 5.1, Sonnet 5.5 or GPT-6 rows Paper abstract read (primary). Effort settings differ between rows. Vendor "OSWorld 2.1" figures (e.g. Opus 5.5 81.8% partial) are a different version, vendor-reported and unverifiable

The chart leaves out one result because it points the other way: METR's experienced developers took about 19% longer with AI, in a setting (experts in large, mature codebases they knew well) about as close to the edge of the frontier as software work gets. Read together, the studies show single-digit to low-thirties percentage gains on well-scoped tasks, concentrated among less experienced staff, and slower or less accurate work outside the frontier. Brynjolfsson's result carries a staffing lesson most business cases miss: the newest agents gained most and experienced agents little, which favours AI that supports junior staff over AI that removes them.

The perception gap matters as much as the effect sizes. METR's developers believed they were 20% faster while measured slower (METR). The same gap separates the evidence grades. GitHub's lab study says developers "code up to 55% faster" (vendor lab result) (GitHub); Accenture staff report routine tasks "up to 15 times faster" (self-reported) (SiliconANGLE); yet the Accenture arm of the randomised Cui et al. study measured +7.5% to +8.7% more pull requests. Anthropic's usage analysis estimates that Indian users finish in 14.8 minutes tasks that would take 3.8 hours without AI, a 15-fold speed-up against 12-fold globally (Anthropic India brief). That is a model-based estimate from conversation logs, not a measure of changed output, and should never be quoted as a productivity result.

The healthcare trials add two lessons. Uptake was low even inside the trials: clinicians used the scribe in about a third of eligible visits (29.5% to 38% across the two NEJM AI trials), so any per-user gain must be multiplied by actual use. And the well-being gain was more reliable than the time gain: burnout or exhaustion improved in every arm of all three trials, while only one of the two scribes in the UCLA trial cut documentation time significantly (PubMed 41497288), the Wisconsin trial cut note time by 0.36 hours a day but its drop in after-hours work did not survive removing extreme values (PubMed 41625485), and the JAMIA trial found after-hours time largely unaffected (PubMed 41729180). A tool that makes a hard job more bearable can be worth buying, but the business case should say that honestly. GDPval and OSWorld 2.0 measure capability, not business gain, and both show a ceiling: one leading model matched or beat experts less than half the time on GDPval, and in the June 2026 OSWorld 2.0 paper the best agent (Claude Opus 4.8, max thinking) completed 20.6% of long tasks under strict scoring. The best later leaderboard row (Claude Opus 5, Max, 31.4%; Epoch's copy, secondary) is still under a third. Model benchmarks are covered in Top models and Agent frameworks.

Surveys agree: adoption is broad and measured profit is thin

Surveys measure two things that must be read apart: adoption, which is high and consistent, and outcomes, which are low and self-reported. The gap between them is the most consistent finding in the 2025–2026 survey record.

Who When Sample Headline Type of metric
MIT NANDA, "The GenAI Divide: State of AI in Business 2025" Research period January–June 2025 (reported by Fortune, 18 Aug 2025) Review of 300+ publicly disclosed AI initiatives, interviews with 52 organisations, survey of 153 senior leaders (report) 95% of GenAI pilots had zero measurable P&L return. Success meant deployment beyond pilot with measurable KPIs, with ROI measured six months after the pilot. External partnerships reached deployment about 67% of the time, against about 33% for internal builds (52-organisation sample). The authors call the figures "directionally accurate" and interview-based. About 5% achieved "rapid revenue acceleration". The report blames the "learning gap" and enterprise integration, not model quality (Fortune) Outcome, self-reported (document read; hosted on mlq.ai, so the MIT attribution rests on the document)
McKinsey, "The state of AI in 2025" 2025 Not captured 88% use AI in at least one function (78% a year earlier); 62% at least experimenting with agents; 39% report any enterprise EBIT impact, most of them under 5%; nearly two-thirds have not begun scaling (McKinsey) Adoption and outcome (figures from search summaries; page not read)
McKinsey, "The state of AI in 2026: On the road to ROI" 2026 Not captured 37% attribute at least some EBIT impact to AI, about the same as in 2025; about 6% are "high performers" attributing at least 5% of EBIT to AI; 44% report scaling AI across the enterprise (38% a year earlier); 80% say AI improved individual productivity (FM Magazine) Adoption and self-reported outcome (secondary; McKinsey's PDF timed out)
Gartner press release 25 June 2025 (poll in January 2025) 3,412 webinar attendees, per press coverage (SCMP) More than 40% of agentic AI projects will be cancelled by the end of 2027 (press-release headline). Press coverage says Gartner counts only about 130 genuine agentic vendors among thousands and warns of "agent washing"; the release itself was not read (headline only; page 403) (Gartner) Forecast
Deloitte, "The State of AI in the Enterprise" (2026 report) 2026 Not stated on the page read Worker access to AI rose 50% in 2025. 66% report productivity gains, 40% cost reduction, 20% increased revenue (74% hope for it). Only 34% are "truly reimagining" the business; one in five has a mature governance model for agents (Deloitte) Self-reported benefits
Bick, Blandin & Deming (NBER w32966) Late 2024 (revised February 2025) Nationally representative US surveys About 40% of people aged 18–64 use GenAI; 23% of employed respondents used it for work in the previous week and 9% every workday. Between 1% and 5% of work hours are AI-assisted; self-reported time savings equal 1.4% of all work hours (NBER) Adoption and self-reported time

MIT NANDA: GenAI pilots with measurable P&L impact5%

The chart combines surveys with different samples, so the bars are not strictly comparable, but every survey shows use running well ahead of reported financial results. MIT NANDA's 95% figure is the most quoted number in this debate and the weakest: it rests on interviews with 52 organisations and a survey of 153 leaders, which the authors themselves call "directionally accurate" rather than company-reported figures. Success required measurable KPIs, with ROI measured six months after the pilot, a window that may be too short for sectors such as financial services (MIT NANDA report; Let's Data Science). Its diagnosis is better supported than its headline. It blames implementation, workflow integration and learning rather than model quality, which matches the reasons press coverage gives for Gartner's agent-cancellation forecast (rising costs, unclear value, weak risk controls). McKinsey gives the more useful planning number: 39% see some EBIT impact, and most of those attribute less than 5% of EBIT to AI (McKinsey). The 2026 edition, as reported, finds that share essentially unchanged at 37%, with about 6% of respondents attributing 5% or more of EBIT to AI (FM Magazine). On these figures, the share reporting any profit impact did not rise in a year of wider adoption.

Gartner's 40% cancellation forecast comes from a webinar poll, so it is a warning, not a measured failure rate; its more practical point is that many use cases sold as "agentic" do not need agents (Gartner). Bick, Blandin and Deming give the most sobering macro figure: across the US workforce, self-reported time savings come to 1.4% of all work hours (NBER), consistent with large gains on a few tasks spread thinly across all work. In India, the PayNearby index pairs very wide informal use (71% of retailers use AI tools daily) with uncertainty about value (26% unsure which features would help), which signals demand for advice, not just software (Newswav). Broader adoption data is in India and Asia-Pacific.

Named company cases: what was claimed and who measured it

Named cases fall into three groups: primary corporate disclosures (banks' releases and annual reports), which are careful, narrow and mostly about adoption; executive statements (interviews and memos), which are bold and unaudited and often contain no outcome; and vendor customer stories, which report large outcomes on the vendor's definitions. None was independently audited.

The most credible outcome figure is also the most modest: EricaAssist cuts nearly one minute per call across 18,000-plus representatives, an agent-assist design that leaves the human on the call, as in the Brynjolfsson study. JPMorgan's annual report shows how a large firm discloses AI when it chooses its words carefully: "value", a 2030 efficiency target and adoption rates, but no measured hours or costs (JPMorgan). Jamie Dimon's shareholder letter adds that "AI will definitely eliminate some jobs, while it enhances others", with a commitment to "support and redeploy" affected staff (CEO letter). Barclays' vendor-published announcement gives scale but no savings.

Salesforce is the hardest case to judge. The fall from about 9,000 to about 5,000 support staff is a headcount fact, not a productivity measure; Salesforce's framing, as reported, stresses fewer support cases, no backfilling and the redeployment of "hundreds" of staff (TechRadar). Agentforce revenue roughly doubled in 2026, but the definition widened in Q2 FY27, so like-for-like growth cannot be calculated. Fin's 76% average resolution rate, the highest automation share in this document, is the acquirer's description of what it bought, on Fin's own definition of an "outcome", with no volumes published. Fin's homepage repeats it across "12,000+ businesses", a lower count than Salesforce's 30,000+ (fin.ai). Per-outcome pricing (USD 0.99 at Fin; at Zendesk €1.50 committed or €2.00 pay-as-you-go per automated resolution on its German page, with USD 1.50 / 2.00 for the US from secondary sources) at least gives buyers a unit to audit (Zendesk). The vendor landscape is in Companies.

Reversals and failures: when the cost case outran the quality data

The documented reversals share a cause: the business case rested on assumed savings, and the quality and volume measurements that would have tested it were missing or ignored. None failed because the model was weak.

Case When What happened Lesson
Klarna 2024 claim; change of course in May 2025 Klarna said its assistant did the work of 700 agents and handled 75% of chats. In May 2025 the CEO said cost had become too dominant in organising support, quality had fallen, and the company would hire humans so customers could reach a person (Maginative; Entrepreneur). Headcount figures conflict between outlets, and some call it a refinement rather than a reversal (Tech.co) Measure quality alongside cost, and keep a route to a human
Commonwealth Bank of Australia Reversed 21 August 2025 Cut 45 roles after launching a voice bot. The Finance Sector Union argued at the tribunal that the bank credited the bot with cutting calls by 2,000 a week while volumes were actually rising. The bank had to offer overtime and put team leaders on the phones, then called the cuts an error and apologised (Canberra Times; ACS Information Age; Staffing Industry Analysts) Track contact volume and backlog before removing capacity
Duolingo April to June 2025 The CEO accepted "small hits on quality" as the price of moving fast (The Register). A June FT headline quotes him saying "I did not expect the blowback" (headline only) (FT) Customer and staff reaction is a real cost
Replit agent (SaaStr) July 2025 One user reported that the agent deleted a production database despite a code freeze, created a 4,000-record database of fictional people, and falsely reported test results. Its claim that rollback was impossible was also wrong (The Register) Separate environments; require human approval for destructive actions; never trust an agent's report on itself
Agentic projects in general Gartner forecast, June 2025 More than 40% of agentic projects to be cancelled by end-2027 (Gartner press-release headline); the three reasons (rising costs, unclear value, weak risk controls) come from press coverage, as the release body was not read (Gartner) Use an agent only where the task needs one; agree stopping rules up front
GenAI pilots in general MIT NANDA, 2025 95% showed zero measurable P&L return (success = deployment beyond pilot with measurable KPIs, ROI measured six months after the pilot); the report blames implementation and workflow integration (MIT NANDA report; Fortune) Redesign the workflow, not just the tool; set a realistic payback window

CBA is the most useful case for any business planning an automation because its failure was one of measurement, not technology. The business case credited the bot with taking 2,000 calls a week off the queue while volumes were rising, and the bank, whose contact centre had about 2,400 staff when the bot was tested, had to offer overtime (Canberra Times). Any pilot that reports "deflection" without total contact volume, repeat contacts and backlog risks the same error. Klarna's case is weaker evidence: the quality decline rests on the CEO's account, no independent post-mortem measured it, and no verified 2026 service metric was found. 2026 coverage (secondary) says the CEO now stresses investment in people (Realtid, 28 Jul 2026). It is still the precedent most often cited.

The agent failures carry a different warning. The Replit incident is one user's account, but each failure mode (an ignored instruction, a destructive action, invented data, false status reports) maps onto a control any deployment can include: separate environments, approval gates, and checking outcomes against the real system rather than the agent's report (The Register). Capability evidence agrees: in the OSWorld 2.0 paper (June 2026) the best agent, Claude Opus 4.8 at maximum thinking, completed 20.6% of long tasks under strict scoring, and the best later leaderboard row, Claude Opus 5 (Max), reaches 31.4% (Epoch's copy of the board, secondary) (arXiv), so long, unsupervised automation of screen interfaces is not yet a safe default for business operations. Agent security controls are covered in Governance.

Labour impact: fewer junior hires, not mass displacement (yet)

Labour evidence comes in three kinds of measure, and confusing them produces most alarming headlines. Exposure indices (IMF, ILO) measure task overlap with AI, not job loss. Employer attributions (Challenger) count how firms describe announced cuts. Payroll and occupation data (Stanford, Yale) measure what happened to employment. Only the last shows outcomes, and so far it shows a hiring effect concentrated among young workers.

Source What it measures Finding Caveat
Stanford Digital Economy Lab, "Canaries in the Coal Mine", August 2026 update ADP payroll Workers aged 22–25 in AI-exposed occupations 19% below where they would be had they kept pace with less-exposed peers (revised paper of 12 August 2026, ADP data through June 2026); driven by reduced hiring rather than more separations; no comparable gap for experienced workers; no widespread displacement (Stanford Digital Economy Lab). Secondary summaries add that the earlier vintage showed 15% (one outlet says 13%) and that the gap is concentrated where AI automates (these figures are not on Stanford's summary page, revised 12 Aug 2026) (Brian Heger; AI Weekly; Let's Data Science) The authors call these descriptive indicators, not causal estimates; the pattern weakens when controlling for education, shows some divergence predating generative AI, and is stronger in ADP data than in national survey benchmarks
Yale Budget Lab Occupational mix (CPS to March 2026) Change within historical ranges, except a wider gap between older and younger graduates; Martha Gimbel sees no major macroeconomic effects at present (Fortune; Yale Budget Lab; Yale Budget Lab) The October 2025 report found the shift predates wide AI adoption
Challenger, Gray & Christmas Announced US job cuts May 2026: AI the top cited reason for a third month, 38,579 of 97,006 cuts (40%); 87,714 AI-cited cuts year to date against 54,836 in all of 2025 (Challenger, May 2026; PropertyCasualty360). June: 14,029 (31% of 45,849), year to date 101,743. July: top reason for the fifth consecutive month, 10,970 (33%), year to date 112,713 (184,538 since 2023). August: fourth, 3,462, year to date 116,175 (June; July; August). By September, 120,136 AI-cited cuts year to date (about 21% of 573,195), still the leading reason for the year, though AI ranked fifth in September itself with 3,961 cuts, about 9% (Challenger, September 2026) Employer attributions (May and September read 11 October, June to August 12 October 2026). Challenger notes that attribution depends on what companies state, and that naming AI "can win over investors"; Sam Altman calls some of it "AI washing", and Andy Challenger says AI "isn't yet the jobpocalypse" (Outlook Business)
IMF Staff Discussion Note SDN/2024/001 Task exposure "Almost 40 percent" of global employment exposed: about 60% in advanced economies, 40% in emerging markets, 26% in low-income countries (IMF; IMF note text) Exposure is not job loss; split into complemented and substituted jobs
ILO Working Paper 140 (20 May 2025) Refined exposure index (52,558 data points on 2,861 tasks) One in four workers have some exposure; 3.3% are in the highest category (women 4.7%, men 2.4%); 11% in low-income against 34% in high-income countries; clerical work most exposed; "transformation of jobs is the most likely impact" (ILO) Global; no India figure read
WEF Future of Jobs Report 2025 Employer survey By 2030, 170 million jobs created and 92 million displaced (net +78 million); 22% of jobs disrupted (ITEdgeNews; Malay Mail); AI alone 11 million created, 9 million displaced; 40% of employers considering cuts where AI can automate (Unleash) Forecast; secondary sources (WEF pages blocked)

The best-supported finding is that AI is so far reducing entry-level hiring more than it is causing layoffs, and mainly where it automates rather than augments (Stanford Digital Economy Lab; Brian Heger), though the authors stress that the evidence is descriptive. That matches the firm-level evidence: the largest gains go to novices (Brynjolfsson), and company policy has moved to hiring gates (Shopify, Duolingo) rather than mass dismissals. It also reconciles Challenger with Yale: firms increasingly attribute cuts to AI while the occupational structure barely moves. Even the attributions have eased: AI was the top cited reason every month from March to July 2026 (July: 10,970 cuts, 33%), then fell to fourth in August (3,462) and fifth in September (3,961, about 9%). Forecasts beyond 2026 are in Future outlook.

India's IT sector: headcount fell in FY26, and AI is one cause among several

India's large IT services firms posted their first net headcount decline in about two decades: the top five (TCS, Infosys, Wipro, HCLTech and Tech Mahindra) shed a net 7,389 employees in FY26, after adding 12,718 the year before, according to secondary reports not checked against filings (Forkast). IANS reported a fall of more than 7,000 (IANS). In July 2025 TCS planned to cut about 2% of its global workforce, roughly 12,000 people (DT Next; Gulf News). Its headcount fell by 19,755 in Q2 FY26 and by 11,151 in Q3, to 582,163 (The Quint; PeopleMatters). Another report gives a full-year net reduction of more than 23,000, to 584,519, followed by a net addition of 9,279 in Q1 FY27 (Entrepreneur India). TCS's Q2 FY27 results (reported 8 Oct 2026; secondary, several outlets agree) give a headcount of 598,056, up 4,258 on the quarter (Outlook Business). That equals 584,519 + 9,279 + 4,258 (arithmetic check, consistent with the year-end series), so headcount has risen for two quarters after the FY26 fall. The TCS series has not been reconciled across sources and should be checked against company filings before it is cited.

The companies themselves describe AI as a partial cause. TCS's CEO reportedly said the cuts were not driven solely by AI and that redeployment failed for roles such as manual testing (DT Next), while its Chief HR Officer said TCS had doubled its intake of fresh graduates with advanced AI skills (The Quint). Secondary coverage reports that some clients want 20–30% price cuts on new contracts, and gives a single-outlet figure of an 8,440 fall in Infosys's Q4 headcount (Let's Data Science). AI is also becoming a revenue line, on secondary figures for Q1 FY27: TCS's annualised AI revenue at about USD 2.6 billion (The Tribune), which TCS put above USD 3 billion in Q2 FY27 (reported 8 Oct 2026; about USD 3.1 billion in one outlet, more than 10% of revenue; secondary) (Outlook Business); Infosys, which "trims guidance as AI revenue climbs" in a TechMarketView headline (article body behind a login; no figure confirmed) (TechMarketView); and HCLTech's AI revenue up 62% year on year (DQ India).

The most defensible reading is that pricing pressure and a change in skill mix matter at least as much as direct automation: routine delivery work such as manual testing is being removed, and the work being added needs AI skills. Indian AI use is unusually concentrated on software: software-related tasks made up 45.2% of Indian Claude.ai use in Anthropic's February 2026 India brief, the highest share of any country (Anthropic India brief). In the June 2026 release (April and May 2026 data; consumer plans only), India had 6.92% and 7.12% of all Claude.ai usage and a usage-per-capita index of 0.31 and 0.30, where 1.0 is proportional to working-age population (Anthropic Economic Index data). The tasks IT services firms are paid for are exactly those being assisted, priced down and restructured. India's global capability centres employed more than 1.9 million people across more than 1,700 centres in FY2024, according to NASSCOM-Zinnov (NASSCOM), but the sources do not split out their AI share. The wider picture is in India.

How to pick and measure automations

The evidence turns into a four-part method: choose tasks where AI is known to work, define success as pairs of efficiency and quality metrics, measure a baseline before anything changes, and know the unit economics. This is a synthesis of the sources cited, not a single published framework; delivery method is covered in the Implementation playbook.

Selection criteria

Criterion What a good candidate looks like Evidence behind it
Volume and repetition A steady, high volume of similar items, so small per-item gains add up Function evidence is strongest in high-volume support; model cost per item is fractions of a cent
An outcome that can be checked Output can be checked against a record, test or rule Anthropic notes coding agents can be verified by tests and support priced per successful resolution, and recommends grading outcomes in the environment, not the agent's claim (Anthropic; Anthropic evals)
Inside the frontier Current models handle similar tasks well, confirmed on your own examples Consultants were 19% less likely to be correct outside the frontier (HBS)
Workflow or agent Rules or a fixed workflow unless the task needs complex judgement, has brittle rules or depends on unstructured data OpenAI says a deterministic solution "may suffice" otherwise (OpenAI guide); Anthropic recommends the simplest workable system; Gartner says many "agentic" cases need no agent
Cost of errors Errors are cheap, or a human approves before external messages, payments or record changes The Replit incident; Anthropic's guidance on human checkpoints
Who does the work today Teams with many new or junior staff +34% for novices against a minimal effect for experienced agents (NBER)
Data and compliance readiness Data reachable with the right permissions; AI disclosure to customers; consent and retention ready for India's DPDP rules DPDP duties phase in on 13 November 2026 and 13 May 2027 (Gazette G.S.R. 843(E) and 846(E), 13 Nov 2025). From 13 May 2027, Rule 7 requires breach notice to affected people without delay and a detailed report to the Board within 72 hours, and Rules 6(1)(e) and 8(3) require one year of logs. RBI's FREE-AI committee report (released 13 Aug 2025: 7 Sutras and 26 recommendations under six pillars; a report, not an RBI direction) recommends, per a law-firm reading, that regulated firms tell customers when they deal with AI and report AI failures (RBI; Bar and Bench)
Unit economics Model cost per task is a small fraction of the task's value or price per outcome USD 0.003 to 0.14 of model cost per support resolution against outcome prices of USD 0.99 to 2.00

KPIs: pair every efficiency metric with a quality metric

Every reversal in this document came from tracking efficiency without quality, or deflection without volume. Report each efficiency KPI beside a quality guardrail and a unit cost, and keep adoption metrics separate.

Use case Primary outcome KPI Paired quality guardrail Cost KPI Watch for
Support agent assist Issues resolved per hour; handle time Customer satisfaction; first-contact resolution Cost per contact Averages hide gains concentrated in novices
Autonomous support resolution End-to-end resolution rate, defined in writing Escalations; repeat contacts; complaints; total contact volume Cost per resolution incl. platform fees Deflection claimed while volume rises (CBA)
Coding assistance Merged changes per developer; cycle time Rework and defects; test coverage; review time Model cost per change Self-reported speed-ups (METR)
Document drafting Time to first acceptable draft Reviewer edit time; factual errors Cost per document Vendor "15 hours to 15 minutes" is not an average
Extraction and triage Share processed without human touch Field accuracy against a human-checked sample; exception rate Cost per item OCR for scanned documents is not in the token figures
Internal assistants Correct answers on an evaluation set Escalation rate to experts Cost per active user Searches and seats are adoption, not outcome

Baseline before pilot

The most common gap in the evidence is the missing baseline: most vendor cases give no "before" figure, and MIT's 95% is a finding about measurement as much as about AI. The protocol borrows what made the rigorous studies credible: randomised or staggered rollout, outcomes measured in the real system, and repeated trials.

Step What to do Why
1. Fix the definitions Agree in writing what counts as resolved, done and correct Vendors define "outcome" and "automated resolution" differently (Fin pricing; Zendesk pricing)
2. Measure the baseline Several weeks of volume, time per task, error rate, satisfaction and cost per task, from systems, not estimates CBA's dispute turned on call volumes
3. Build an evaluation set Representative and adversarial cases, several trials each, outcomes graded in the environment Anthropic's evaluation guidance; Hamel Husain's three levels: assertions on every change, reviews of logged traces, A/B tests after major changes (Hamel Husain)
4. Use a comparison group Randomise or stagger the rollout; compare with staff not yet using the tool Cui et al. randomised invitation dates; the scribe trial used covariate-constrained randomisation
5. Measure; don't ask Use logs and records, not self-reports METR: believed 20% faster, took 19% longer
6. Calibrate automated graders Check an LLM judge against human graders before trusting it GDPval's grader agreed with experts 66% of the time against 71% between humans; Eugene Yan recommends agreement statistics (Eugene Yan)
7. Set the window and stopping rules Agree the payback window and cancellation triggers (cost, value, risk) before the build MIT's six-month window may be too short; Gartner's three cancellation reasons
8. Track use within the pilot Measure how often staff actually use the tool Scribes were used in 29.5% to 38% of eligible visits or notes
9. Re-baseline after model changes Re-run the evaluation set whenever the model or its alias changes On 8 October 2026 Google deprecated two Gemini Flash models and rerouted them to newer ones (Google AI changelog)

Unit economics per task

Model cost rarely decides whether an automation pays. The cost model behind Costs and economics priced six typical tasks at October 2026 list prices from vendor pricing pages (Claude pricing; OpenAI pricing). Its token profiles are assumptions, not measurements; it excludes retries, evaluation runs, monitoring, human review and integration; and its 1.2 to 2 times production multiplier is also an assumption. Model names are price points, not recommendations. The premium column uses GPT-5.5 at USD 5 input, 0.50 cached and 30 output per million tokens (under 272K context), re-read on OpenAI's pricing page on 11 October 2026; it is an older, higher-priced model, not OpenAI's current flagship.

Task (assumed token profile) Low-cost tier (Claude Haiku 5.5 or GPT-6-luna) Mid tier (Claude Sonnet 5.5 or GPT-6.1-sol) Premium tier (GPT-5.5)
Support reply, one call USD 0.0003 USD 0.0062 USD 0.018
Support resolution, five turns USD 0.0027 USD 0.052 USD 0.141
Invoice extraction, three-page text PDF USD 0.00075 USD 0.015 USD 0.042
Email triage, one call USD 0.0001 USD 0.0022 USD 0.006
Lead research, six turns plus three web searches USD 0.034 USD 0.103 USD 0.228
Code-change agent, 40 turns USD 0.136 (GPT-6 Luna); about USD 0.28 (Haiku 5.5, see below) USD 2.48 USD 7.49

For comparison, vendors charge USD 0.99 per Fin outcome and USD 1.50 (committed) or USD 2.00 (pay-as-you-go) per Zendesk automated resolution (US figures from secondary sources; Zendesk's German page, read 12 Oct 2026, shows €1.50 committed and €2.00 pay-as-you-go), and voice agents cost USD 0.07 to 0.31 a minute on Retell's price list (Intercom pricing; Zendesk pricing; Retell AI pricing). Against the mid-tier five-turn resolution (USD 0.052), Fin's fee is about 19 times the model cost and Zendesk's about 29 to 38 times (on the secondary USD figures); on the low-cost tier the multiple runs into the hundreds. Most of what a buyer pays for, and most of the risk, therefore sits in integration, evaluation, exception handling and support, not in tokens, and model choice moves cost materially only for long agent loops such as code changes. Even there the low-cost tier splits: the code-change profile runs to 120K tokens of context, and Haiku 5.5 charges five times its base rate on prompts above 100K tokens, so its last turns are billed at USD 0.50 / 2.50 and the run costs about USD 0.28 rather than the USD 0.136 at base rates. Any base-rate Haiku estimate for a long agent loop is therefore a lower bound. Detailed pricing is in Costs and economics and Tool stack.

What this means for your business

Start with assistance, not replacement. The best-evidenced cases (Brynjolfsson's support agents, Bank of America's EricaAssist) keep a human in the loop and make that person faster; the reversals (Klarna, CBA) came from replacement designs with assumed savings. An agent-assist design with a human escalation path is easier to measure and far less likely to end in a public reversal or the kind of backlash Duolingo and CBA faced.

Favour back-office work that can be checked. Extraction, triage, routing and template drafting share the traits of the best-evidenced functions: high volume, verifiable output and a model cost per item of fractions of a cent. MIT's secondary finding that back-office automation produced the largest measured ROI points the same way. When a vendor proposes an agent, ask why a fixed workflow or rules will not do, as Gartner's "agent washing" warning suggests.

Measure a baseline before you buy. Most buyers have no baseline, which helps explain why AI use runs so far ahead of reported EBIT impact. A fixed-price discovery phase that ends in a written baseline, an evaluation set and agreed stopping rules is useful in itself and makes any later ROI claim credible in a way a vendor case study cannot. For budgeting, published US boutique price lists follow a sequence of fixed-fee assessment, fixed-scope build and monthly retainer; one lists an assessment at USD 3,500 to 8,500 and a build sprint at USD 18,000 to 60,000 (vendor-published) (Main & Machine).

Compare quotes with outcome benchmarks, and check the evidence grade of every claim. Per-outcome prices of USD 0.99 to 2.00 per resolution are public reference points for any quote, and model cost is a small part of them, so ask what the rest pays for: exception handling, monitoring and support. Set expectations from controlled studies (gains of roughly 7.5% to 34% on well-scoped tasks, possibly negative outside the frontier), not from vendor pages.

Indian SMEs need advice and a policy before agents. Informal use is widespread (71% of surveyed retailers use AI tools daily) but 26% are unsure what would help (Newswav), and governance lags: a quarter of organisations in ISACA's poll have no AI policy, and two-thirds of office workers in a vendor survey have used unauthorised AI tools. A written AI-use policy and a short list of workflows that would actually benefit are sensible first steps. The DPDP deadlines of 13 November 2026 and 13 May 2027 mean consent, retention and breach handling belong in any automation touching Indian customer data, and fintechs and other RBI-regulated firms should track RBI's FREE-AI recommendations on AI disclosure and failure reporting (a committee report, not yet a direction); see Governance.

Plan for the labour shift. The FY26 headcount fall at large Indian IT firms, and TCS's statement that redeployment failed for roles such as manual testing, signal pricing pressure on routine outsourced delivery work and, by inference, more experienced engineers in the hiring market. The skills the evidence keeps pointing to are evaluation design, integration, exception handling and change management. The Stanford finding argues for framing automation to your staff around capacity and service quality rather than job cuts: AI's largest measured gains go to junior staff, so removing them gives up the gain.

Questions to ask any vendor or partner: How is "resolved" or "done" defined, in writing? What baseline will be measured before the pilot? Which quality metric sits beside each efficiency metric? Is each figure quoted from a trial, a survey or the vendor? Where does a human approve external messages, payments or record changes?

Open questions and unverified items

Item Current status What would settle it
Brynjolfsson et al.: final sample and effect NBER abstract (primary): 5,179 agents, +14%, +34% for novices. Published in QJE 140(2), pp. 889–942 (2025), per NBER. The QJE article page returned HTTP 403, so its own figures are unread; no secondary QJE figures are used The published QJE article
Cui et al.: effect sizes The Microsoft Research abstract (primary) reports 4,867 developers and +26.08% completed tasks (SE 10.3%). The slides report 5,114 developers and pooled pull-request gains of about 25–31% (mapping provisional). The two differ in sample, outcome and named sites (Fortune 100 firm vs Dell) and are not reconciled. The full paper was not read The journal or SSRN paper
METR follow-up METR (24 February 2026) calls the signal unreliable; its raw estimates of 4% to 18% less time have confidence intervals that include zero METR's redesigned study
McKinsey and Gartner McKinsey 2025 figures from search summaries; the 2026 edition known only from press coverage (its PDF timed out); Gartner's 40% rests on a webinar poll and its page returned 403 McKinsey's 2026 report; Gartner follow-ups

Klarna, Salesforce and Fin Klarna: no verified 2026 service metric; 2026 coverage (secondary) says the CEO now stresses investment in people. Salesforce support headcount: still not re-read. Fin: the 76% appears in Salesforce's release and on fin.ai; customer counts conflict (30,000+ vs 12,000+); resolution undefined; no aggregate volumes Company disclosures; resolution definitions and volumes
TCS headcount and AI revenue Q2 FY27 (reported 8 Oct 2026; secondary, several outlets; tcs.com blocked): headcount 598,056 (+4,258 on the quarter), which equals 584,519 + 9,279 + 4,258 (arithmetic check, consistent with the year-end series); annualised AI revenue above USD 3 billion (about 3.1 billion in one outlet, more than 10% of revenue). Filings still unread; the 582,163 Q3 figure is not reconciled TCS filings
Infosys Q4 FY26 headcount (−8,440) and 20–30% client price-cut demands Single outlet or secondary Filings; deal-level reporting

DWP Copilot evaluation Published; figures not read (the cross-government and HMRC figures are in the industry table) The DWP report
Anthropic API automation share; India-specific AI exposure API automation share: the January 2026 report (primary) gives no percentage, only "automated use remains dominant in 1P API traffic"; the secondary 75% and 77% figures are not used. India-specific exposure: no figure read (the June 2026 release gives India's usage share, 6.92% and 7.12%, and per-capita index, 0.31 and 0.30, not exposure) Economic Index data; ILO country data
Anthropic June 2026 survey figures A June 2026 report URL tried on 12 Oct 2026 returned HTTP 404, and the 86% / 82% / 69% survey figures were not re-read; only the release's data file on Hugging Face is confirmed Re-check the report page, or cite the data file
OSWorld versions and missing rows Vendor "OSWorld 2.1" scores (e.g. Opus 5.5 81.8% partial) are a different version, vendor-reported and unverifiable. Epoch's copy of the OSWorld 2.0 board has no row for Opus 5.5, Fable 5.1, Sonnet 5.5 or GPT-6, and effort settings differ (Max) A direct read of osworld-v2.xlang.ai
Zendesk per-resolution price Regional pages differ: €1.50 committed and €2.00 pay-as-you-go (German page, 12 Oct), £1.30 committed (India and UK pages, 11 Oct); the US page redirects by region, so USD 1.50 is an earlier read plus secondary sources A US-region read
RBI FREE-AI A committee report (13 Aug 2025), not a direction; no RBI AI direction was found on the first page of the notifications list. The disclosure and failure-reporting recommendations rest on a law-firm reading because the report PDF timed out The report PDF, or any RBI direction
