Mature teams evaluate in one loop, but sector rules barely reach generative AI

The best companies turn every production failure into a test and calibrate their judges against experts, while most sector regulators still have no rules for testing generative AI agents.

Key findings

  • Mature software teams run the same loop. They combine a regression suite in CI, calibrated LLM judges, internal dogfood and online business metrics (GitHub, Jan 2025; Shopify, Aug 2025).[1][1] GitHub, How we evaluate models for GitHub Copilot Primary[2][2] Shopify Engineering, Building production-ready agentic systems Primary
  • The usual release gate is "no regression against the production baseline". Few teams publish an absolute pass score.[1][1] GitHub, How we evaluate models for GitHub Copilot Primary[3][3] Claude customer story, Intercom Vendor
  • The best golden sets come from production traffic and failures. Shopify replaced hand-written sets with samples of real merchant conversations (Aug 2025).[2][2] Shopify Engineering, Building production-ready agentic systems Primary
  • Teams now check their LLM judges against humans. Shopify raised judge agreement from a kappa of 0.02 to 0.61, close to the human level of 0.69 (Aug 2025).[2][2] Shopify Engineering, Building production-ready agentic systems Primary
  • Banks gate each use case and validate independently, but publish few numbers. ING gives the most concrete figure: daily regression tests on 500 real customer chats, plus A/B tests (snippet only).[4][4] OpenAI customer story, Morgan Stanley Vendor[5][5] The Muse, JPMorgan model risk job listing Single source[6][6] AI Expert Network, AI at ING Secondary
  • Evaluation lags observability. In a vendor survey of 1,340 respondents (Nov–Dec 2025), 89% trace their agents but only 52% run offline evals and 37% run online evals.[9][9] LangChain, State of Agent Engineering Vendor
  • Public failures share one cause: the builder controlled the metric. Klarna, Deloitte Australia and NYC's hiring-audit law all show it (2023–2025).[7][7] BNN Bloomberg / AP, Deloitte to partially refund Australian government Secondary[13][13] NY State Comptroller, Enforcement of Local Law 144 Primary[42][42] Maginative, Klarna dials back AI customer service Secondary
  • The main US bank guidance excludes generative AI. SR 26-2 (17 Apr 2026) carves out generative and agentic AI and sets no enforceable standards.[10][10] Federal Reserve, SR 26-2 attachment Primary[49][49] Federal Reserve, SR 26-2 letter Primary
  • Insurance has the densest testing duties outside AI law. EIOPA expects pre-release and ongoing tests, fairness metrics and due-diligence tests of bought AI (Aug 2025).[11][11] EIOPA, Opinion on AI governance and risk management Primary
  • Mandates without enforcement or a paying buyer fail. NYC Local Law 144's audits went largely unenforced, and CHAI's health assurance labs never launched (2025–2026).[13][13] NY State Comptroller, Enforcement of Local Law 144 Primary[14][14] Fierce Healthcare, Inside CHAI's failed assurance labs Secondary

Mature teams run one seven-step loop, and every production failure becomes a test

Public cases from GitHub, Shopify, ING, Notion, Intercom and Abridge describe the same loop. It runs from real traces, through a release gate, to online monitoring and back.

The loop starts with real traffic, not invented test cases. Teams read production conversations, group the failures and build test sets from them. They gate releases on those sets in CI, grade hard cases with calibrated judges, roll out in stages and monitor live quality.[1][1] GitHub, How we evaluate models for GitHub Copilot Primary[2][2] Shopify Engineering, Building production-ready agentic systems Primary[6][6] AI Expert Network, AI at ING Secondary Each new failure goes back into the datasets.[17][17] Braintrust, Notion case study Vendor

The usual gate is relative, not absolute. Teams release when a candidate shows "no regression against the production baseline".[1][1] GitHub, How we evaluate models for GitHub Copilot Primary[3][3] Claude customer story, Intercom Vendor Few publish a fixed pass score. GitHub says it uses judgement when metrics conflict.[1][1] GitHub, How we evaluate models for GitHub Copilot Primary Practitioner guides describe the method for the first four steps in more depth; this chapter adds the company evidence.[18][18] Husain and Shankar, evals FAQ Secondary

The Best Teams Turn Every Failure Into a New Test

The seven-step evaluation loop described by GitHub, Shopify, ING, Notion, Intercom and Abridge, with a real example at each step.

1/7

Step 1· Before release

Analyse errors on real traces

Read real production conversations and group the failures.

ExampleShopify samples real merchant chats; three or more product experts label each one.

Step 1 of 8: Step 1, error analysis on real traces, appears with the Shopify example.

Start with real failures. Shopify dropped hand-written golden sets. It now samples real merchant conversations, and at least three product experts label each one.[2][2] Shopify Engineering, Building production-ready agentic systems Primary
Turn them into a regression set. A regulated set needs hundreds of real cases, not thousands. ING re-ran 500 real chats daily, and Box gates launches on 330 questions.[6][6] AI Expert Network, AI at ING Secondary[15][15] Braintrust, customer stories Vendor
Gate every change in CI. GitHub runs more than 4,000 offline tests, mostly automated.[1][1] GitHub, How we evaluate models for GitHub Copilot Primary Dropbox runs more than 10,000 tests after every merge.[15][15] Braintrust, customer stories Vendor
Calibrate the judge before trusting it. Shopify's first judge agreed with experts at a kappa of 0.02, close to random. Calibration lifted it to 0.61, near the human-to-human 0.69.[2][2] Shopify Engineering, Building production-ready agentic systems Primary
Release in stages. GitHub staff use candidate models first, like a canary.[1][1] GitHub, How we evaluate models for GitHub Copilot Primary ING piloted with 10% of Dutch mobile-chat users and ran A/B tests.[6][6] AI Expert Network, AI at ING Secondary Shopify also replays real goals through an LLM merchant simulator before release.[2][2] Shopify Engineering, Building production-ready agentic systems Primary
Keep testing in production. GitHub runs daily tests against live models to catch silent changes.[1][1] GitHub, How we evaluate models for GitHub Copilot Primary Intercom scores live conversations, and Abridge tracks clinician edits and star ratings.[16][16] createwith.com, Intercom Monitors Secondary[8][8] Abridge, The science of AI evaluation Vendor
Close the loop. At Notion, a data specialist turns failures into new eval sets.[17][17] Braintrust, Notion case study Vendor The loop then starts again at step 1.
Few teams run the whole loop. In LangChain's vendor survey, 45% of teams with agents in production run online evals, and 23% do not evaluate at all.[9][9] LangChain, State of Agent Engineering Vendor

Figure 1. Steps 1–4 run before release, step 5 is the release, and steps 6–7 run in production. Box, Dropbox and Notion figures come from Braintrust case studies (vendor-authored). Abridge and Intercom figures are self-reported. ING figures are snippet only.

Table 1. Each stage of the loop uses different metrics. Only judge calibration and buyer acceptance compare a system directly with human experts. Source: company engineering blogs and case studies cited in each row.

Software firms publish the best evidence: regression gates, calibrated judges and online metrics

Their own engineering blogs give the clearest numbers. Most other detail comes from case studies written by eval vendors about their customers.

GitHub runs a large offline suite, a judge it audits and a canary step. It runs "more than 4,000 offline tests", mostly in automated CI.[1][1] GitHub, How we evaluate models for GitHub Copilot Primary The team breaks about 100 containerised repositories on purpose, and the model must repair them. Chat quality tests use more than 1,000 technical questions. An LLM judge grades complex answers, and the team calls alignment with human reviewers a challenge.

Shopify gave the most detailed public account of judge calibration. It samples "Ground Truth Sets" from real merchant conversations, labelled by at least three product experts.[2][2] Shopify Engineering, Building production-ready agentic systems Primary Calibration raised the judge's Cohen's kappa from 0.02 to 0.61, against 0.69 between two humans. The team trusts a judge when blind reviewers cannot tell judge labels from human labels.

Calibration took Shopify's judge from random to almost human

Figure 2. Cohen's κ corrects agreement for chance: 0 is chance level, 1 is perfect. The human bar is the ceiling: how well two experts agree with each other. Bands follow the common Landis and Koch reading. A later, separate fix for reward hacking raised the judge's correlation from 0.66 to 0.75. Source: Shopify Engineering, Building production-ready agentic systems (Aug 2025).[2][2] Shopify Engineering, Building production-ready agentic systems Primary

Training on the evals produced reward hacking. When Shopify ran reinforcement learning against its evals, the model refused tasks, misused tags and invented IDs.[2][2] Shopify Engineering, Building production-ready agentic systems Primary Fixes raised syntax validity from about 93% to 99%. The lesson is simple: hold back a test set that training never sees.

Huge traffic lets online metrics replace much of the offline gate. Cursor trains its Tab model with online reinforcement learning on accept and reject signals.[20][20] Cursor, Online RL for Tab Primary Few enterprises have that volume. Vendor-reported resolution rates also need care. A competitor notes that Intercom changed the denominator of Fin's resolution rate, so rates from different vendors do not compare.[22][22] eesel.ai, Fin response quality Vendor

At Cursor's scale, users are the eval

    • The stack has converged: CI regression, then calibrated judges, then dogfood or canary, then online metrics.
    • Golden sets grow from production failures; nobody writes them fully in advance.
    • Good teams validate their judges against humans and report agreement.
    • Vendor-reported resolution rates do not compare across vendors, because definitions change.
    • No company reports eval headcount apart from AI headcount. Notion's figure of about 70 engineers covers all AI work.

Banks gate each use case and validate it independently, but publish few numbers

Public detail on bank and insurer practice is thin. Banks describe gates and validation, but not set sizes or thresholds. Insurers describe security and privacy, but not test method.

The bank pattern is a gate per use case plus independent validation. Morgan Stanley built "an evaluation (eval) framework to test every AI use case before deployment", according to its supplier OpenAI.[4][4] OpenAI customer story, Morgan Stanley Vendor JPMorgan runs an "AI Center of Excellence" inside its model risk review function. A job listing says it does "independent validation focused on AI/ML models, LLM-based applications, and generative AI systems".[5][5] The Muse, JPMorgan model risk job listing Single source Its CIO said that building generative AI is easier than "the validation and the controls".[25][25] InvestmentNews, JPMorgan joins the AI productivity war Secondary

ING gives the most concrete European bank number. It built a support chatbot with McKinsey's QuantumBlack and piloted it with 10% of Dutch mobile-chat customers.[6][6] AI Expert Network, AI at ING Secondary[27][27] CTO Magazine, ING AI chatbot Secondary[28][28] McKinsey, How ING uses generative AI Vendor The team re-ran 500 real customer chats daily and ran A/B tests. Risk staff joined from the start, and guardrails block mortgage and investment advice. The bot resolved about 20% more queries than the classic chatbot.

Insurers publish almost nothing about test method. AXA's coverage stresses privacy and security, not testing.[30][30] Intelligent Insurer, AXA develops generative AI with Microsoft Secondary[31][31] Microsoft customer story, AXA Vendor A 2025 trade article says insurers red-team both in-house and vendor AI, and warns them not to trust vendors' red-team claims alone.[32][32] InsuranceNewsNet, Red teaming for insurer AI risk Secondary We found no public eval detail for Allianz, Zurich, Lemonade or Goldman Sachs.

    What the finance cases show

    • The pattern "a gate per use case plus independent validation" comes from model-risk habits.
    • Banks keep this habit even where SR 26-2 no longer covers generative AI.
    • Klarna shows the opposite pattern, where cost drove the evaluation.

Public bodies and one health vendor publish the most rigorous methods

Public bodies must justify spending, so they publish more method than firms. In healthcare, one vendor's release gate sets the bar, but it grades itself.

The UK's i.AI runs a buyer-side acceptance test. Its "Consult" tool analysed a Scottish Government consultation and scored an F1 of 0.76 against human reviewers.[19][19] GOV.UK, Humphrey tool reviews consultation responses Primary The differences had a "negligible" effect on the ranking of themes. The government plans more accuracy work before a wider rollout. Its note-taking tool "Minute" reported one hour saved per one-hour meeting in 25 councils, but that is an early pilot figure.[35][35] Computer Weekly, Humphrey AI for council admin Secondary

Self-classification under-reports risk. The Netherlands Court of Audit counted 433 AI systems at 70 central-government organisations in October 2024.[36][36] Accountant.nl, Court of Audit on central government AI Secondary[37][37] Binnenlands Bestuur, Government often skips AI risk assessment Secondary[38][38] NOS, Court of Audit AI report Secondary More than half had no prior risk assessment. Only 5% appeared in the public algorithm register. The audit office saw "an incentive not to classify AI systems as high risk" (our translation). Its figures rest on the ministries' own self-assessments.

Abridge publishes the most rigorous enterprise release gate we found, and wrote it itself. Its test data holds more than 10,000 hours of clinical audio with gold transcripts.[8][8] Abridge, The science of AI evaluation Vendor A release needs blinded head-to-head trials "adjudicated by licensed clinicians". The trials use anytime-valid sequential tests, so the team can stop early without false confidence. Monitoring uses clinician edits, star ratings and links from each note sentence to the transcript.

Independent health studies are rare, but they can contradict vendors. A 2025 study graded ambient notes with a modified PDQI-9 instrument and two blinded reviewers.[41][41] Frontiers in AI, Ambient AI note quality study Primary Ambient notes were more thorough than human notes, but less succinct and more prone to hallucination. Most scribes and admin tools are not medical devices, so the FDA does not review them, and vendors report their own evals.

    • Independent health studies remain rare and small, but the PDQI-9 study contradicts vendor claims on hallucination.

Public failures share one cause: the builder controlled the metric

The public eval failures fall into six groups. In each case, an independent test with a fixed rubric and human-checked grading would probably have exposed the problem.

Klarna let cost become the main evaluation factor. Klarna had claimed its assistant handled two-thirds of chats and did the work of 700 agents.[44][44] tech.co, Klarna reverses AI overhaul Secondary In 2025, CEO Sebastian Siemiatkowski told Bloomberg the AI-first push "went too far" and lowered quality.[42][42] Maginative, Klarna dials back AI customer service Secondary[43][43] Entrepreneur, Klarna CEO reverses course Secondary Klarna then began to rehire human agents.

Evaluation lags observability: about half of agent teams run no offline evals

The best public data comes from LangChain's "State of Agent Engineering" survey. LangChain sells eval and tracing tools, so treat it as a vendor survey.

Teams trace their agents far more often than they test them. The survey ran from 18 November to 2 December 2025 and drew 1,340 responses.[9][9] LangChain, State of Agent Engineering Vendor About 89% of respondents trace or observe their systems. Only 52.4% run offline evals and 37.3% run online evals. Human review (59.8%) still leads LLM-as-judge (53.3%) as a method.

Nine in ten agent teams trace; only half run offline evals

Share of all respondents using each practice, LangChain State of Agent Engineering survey, November–December 2025 (n = 1,340).

Eleven sector regimes demand testing, but none is built for generative AI agents

Banks, insurers, device makers, employers, aviation and public agencies faced testing rules long before AI law. We rated eleven regimes on five questions.

Every regime asks for testing before use, and most for monitoring after. Many also name independence: SR 26-2, SS1/23, EIOPA, NYC Local Law 144 and the OMB memos all do.[10][10] Federal Reserve, SR 26-2 attachment Primary[54][54] Bank of England, SS1/23 model risk management principles Primary[11][11] EIOPA, Opinion on AI governance and risk management Primary[12][12] NYC DCWP, Automated employment decision tools Primary[79][79] OMB M-25-21 (3 Apr 2025) Primary Several accept black-box tests. SR 26-2 allows outcome analysis without code access, and OMB allows query-based tests of a vendor service.[10][10] Federal Reserve, SR 26-2 attachment Primary[79][79] OMB M-25-21 (3 Apr 2025) Primary

Most regimes are guidance, not law, and the newest technology often falls outside scope. Only Colorado's insurance rules, NYC Local Law 144, the EU MDR and the OMB memos bind. SR 26-2 excludes generative and agentic AI in its footnote 3.[10][10] Federal Reserve, SR 26-2 attachment Primary It also states that "non-compliance with this guidance will not result in supervisory criticism". EASA's proposal covers only offline-learning ML.[76][76] EASA, NPA 2025-07 Primary

What to notice

  • The highlighted column has no full mark: no regime is built for generative AI agents.
  • The closest are the OMB memos and the EU device rules, and both are narrow.
  • US bank guidance now excludes generative AI; insurance rules are mostly guidance.

Insurance has the densest testing duties outside AI law. EIOPA's opinion of 6 August 2025 expects tests "before release as well as on an ongoing basis", fairness metrics and drift monitoring.[11][11] EIOPA, Opinion on AI governance and risk management Primary Paragraph 3.11 names "external audits, or performing due diligence testing" for bought AI. Paragraph 3.37 asks for tests of connections to other AI systems through APIs, which fits agents directly. In the US, the NAIC bulletin reached 29 jurisdictions by 3 November 2026, but it stays guidance.[57][57] NAIC, AI model bulletin adoption map Primary Colorado binds, but its quantitative test rule has stalled since September 2023.[60][60] Debevoise, Colorado extends AI regulation Secondary

Mandates without enforcement or a paying buyer fail. NYC Local Law 144 requires an independent bias audit within a year before an employer uses a hiring tool.[12][12] NYC DCWP, Automated employment decision tools Primary The State Comptroller audited enforcement in December 2025.[13][13] NY State Comptroller, Enforcement of Local Law 144 Primary A secondary summary says the audit found 17 potential violations where the city found one.[74][74] GLACIS, Guide to New York AI rules Single source In health, CHAI planned certified assurance labs in 2024.

The rules leave room for outside testers, but only with a buyer. SR 26-2 lets banks validate vendor products "either by internal or outside parties".[10][10] Federal Reserve, SR 26-2 attachment Primary EIOPA names external audits, and OMB M-25-22 requires vendors to give agencies the "access and time necessary" for independent evaluation.[11][11] EIOPA, Opinion on AI governance and risk management Primary[80][80] OMB M-25-22 (3 Apr 2025) Primary Black-box access is enough for many of these duties.

    • Colorado is the only US state with binding insurance AI governance rules.[60][60] Debevoise, Colorado extends AI regulation Secondary It extended its life-insurer rule to private auto and health benefit plans in August 2025; the amendments took effect on 15 October 2025, with governance due by 1 July 2026.
    • Insurers must remediate unfair discrimination "detected through quantitative testing". The quantitative testing rule was drafted in September 2023 and not updated since. The final text dropped a required bias and data-quality evaluation of external data.
    • Bulletin B-10.004 waives the description of quantitative tests in the 2024 and 2025 annual reports.[61][61] Colorado Division of Insurance, Bulletin B-10.004 Primary
  • US healthcare: FDA

    • The PCCP guidance for AI-enabled device software is final; most sources date it to December 2024, a June 2026 CRS report to August 2025.[62][62] Akin Gump, FDA finalises PCCP guidance Secondary[63][63] RAPS, Final FDA guidance on PCCP Secondary[64][64] CRS IF13245, FDA and AI-enabled devices Primary It covers AI broadly; makers agree planned changes and validation methods in advance.
    • The lifecycle guidance is still a January 2025 draft; the device centre's FY2027 agenda (1 Oct 2026) makes its final version an A-list priority.[65][65] RAPS, FDA device centre guidance agenda for FY2027 Secondary The agenda adds a top-priority draft on generative AI conversational devices for mental health and a low-priority item on risk assessment for generative AI devices.
    • The FDA revised its Clinical Decision Support software guidance on 6 January 2026.[64][64] CRS IF13245, FDA and AI-enabled devices Primary

    US healthcare: CHAI

    • An October 2024 draft would have certified independent labs against ISO 17025 and conflict-of-interest tests; final designs were promised for April 2025.[66][66] Fierce Healthcare, CHAI draft model card and lab certification Secondary
    • STAT reported in May 2025 that "CHAI's 'assurance lab' effort is dead".[67][67] Ground News, STAT on CHAI's assurance labs Secondary Becker's reported that the federal government sought to sideline CHAI.[68][68] Becker's, Administration seeks to sideline CHAI Secondary

    EU healthcare: MDR, IVDR and the AI Act

    • MDCG 2025-6 (June 2025) is a joint FAQ of the Medical Device Coordination Group and the AI Board.[71][71] OpenRegulatory, MDCG 2025-6 Secondary[72][72] Reuschlaw, Interplay between MDR, IVDR and the AI Act Secondary
    • Device AI is high-risk under AI Act Article 6(1) when a notified body must assess the device. Makers may embed AI Act testing, monitoring and documentation into MDR or IVDR quality systems, and post-market surveillance can carry the monitoring duties.
    • MDCG 2025-6 gave 2 August 2027 as the start date; the Digital Omnibus moved duties for AI inside regulated products to 2 August 2028.[73][73] Garrigues, Digital Omnibus on AI published Secondary The Rules chapter covers the Omnibus.
  • Employment: NYC Local Law 144

    • An employer may use an automated employment decision tool only after "a bias audit within one year of the use of the tool", must post a summary, and must give candidates notice 10 business days before use.[12][12] NYC DCWP, Automated employment decision tools Primary DCWP began enforcement on 5 July 2023.
    • The State Comptroller audited enforcement on 2 December 2025.[13][13] NY State Comptroller, Enforcement of Local Law 144 Primary A secondary summary says it rated enforcement "ineffective": DCWP found one issue where auditors found 17 potential violations, and 75% of calls about these tools went to the wrong place.[74][74] GLACIS, Guide to New York AI rules Single source We could not check these figures against the report.

    • Proposes a generic "DS.AI" framework for AI assurance, human factors and ethics, covering only offline-learning ML that does not contribute to critical failures. Generative, reinforcement-learning and hybrid AI come later.
    • The next consultation, expected in Q2 2027, embeds the framework into airworthiness, air traffic and drone rules.[78][78] ICAO DGCA61 paper, EASA approach to AI in aviation Primary "Learning assurance" is the most rigorous sector test doctrine we found, but it does not yet reach LLM agents.

    US federal agencies: OMB M-25-21 and M-25-22

    • Agencies must test high-impact AI before deployment; without code, model or data access, they query the service or send evaluation data to the vendor.[79][79] OMB M-25-21 (3 Apr 2025) Primary
    • An in-agency reviewer "who has not been involved in the development" reviews each impact assessment.
    • Agencies test and review AI periodically after deployment; non-compliant AI must stop.
    • Vendors must give agencies the "access and time necessary" for independent evaluation.[80][80] OMB M-25-22 (3 Apr 2025) Primary
    • The EU's model contractual clauses for AI procurement (MCC-AI) exist in High-Risk and Light versions; they are optional.[81][81] Covington Inside Privacy, Updated AI model contractual clauses Secondary
  • What the regimes share

    • Most regimes are guidance, not law; only Colorado, NYC LL144, the EU MDR and the OMB memos bind.
    • Every regime asks for testing before use and monitoring after use.
    • Many name independence: SR 26-2, SS1/23, EIOPA, LL144 and OMB M-25-21.
    • Several accept outside parties: SR 26-2 for vendor models, EIOPA for external audits.
    • Black-box testing is acceptable under SR 26-2 (outcome analysis) and OMB (query-based tests).
    • The newest technology often falls outside scope: SR 26-2 and EASA both exclude generative AI.
    • No regime targets generative AI agents directly.

    Other sectors not checked

    • No US or EU education rule outside the AI Act that demands AI testing was found; we did not search this area in depth.
    • Automotive rules (UNECE, ISO PAS 8800) and EU employment rules (Platform Work Directive) were not checked in this pass.

A mature programme climbs six levels, from vibes to independent assurance

This playbook combines the public cases and the sector rules above. It is our synthesis, not a published standard.

Most teams sit on the lower rungs. About 23% of production agent teams run no evals at all, which is level 0.[9][9] LangChain, State of Agent Engineering Vendor A regression gate built from real traffic, as at Box, Dropbox and Cloudflare, marks level 2.[15][15] Braintrust, customer stories Vendor Calibrated judges with published agreement, as at Shopify, mark level 3.[2][2] Shopify Engineering, Building production-ready agentic systems Primary Level 5 adds a party outside the build team that validates and challenges results. JPMorgan's model risk review and the OMB memos show this level.[5][5] The Muse, JPMorgan model risk job listing Single source[79][79] OMB M-25-21 (3 Apr 2025) Primary

Six levels of evaluation maturity, with a real example at each

A maturity ladder synthesised from public company cases and sector rules, November 2026.

  1. 5. Independent assurance

    Rare outside banks and government A party outside the build team validates and challenges results.

    • JPMorgan MRGR
    • OMB independent review
  2. 4. Closed loop

    Leading teams Staged rollout, online metrics and A/B tests; failures flow back into the suite.

    • GitHub
    • ING
    • Abridge
  3. 3. Calibrated grading

    Leading teams Judges carry published agreement with experts; simulators test multi-turn flows.

    • Shopify
  4. 2. Regression gate

    Established A suite built from real traffic runs in CI; no regression against production.

    • Box
    • Dropbox
    • Cloudflare
  5. 1. Smoke tests

    Common starting point A small fixed set runs before releases.

    • Many early teams
  6. 0. Vibes

    ≈23% of production agent teams Developers try prompts by hand; no stored tests.

    • LangChain survey, Nov–Dec 2025

What to notice

  • No survey offers a widely used maturity model; this ladder is our synthesis.
  • Each level keeps the practices of the levels below it.

Start with hundreds of real production cases: ING used 500 chats and Box 330 questions.[6][6] AI Expert Network, AI at ING Secondary[15][15] Braintrust, customer stories Vendor Add each new production failure as a test. Keep a separate frontier set for new capabilities, as Notion does.[17][17] Braintrust, Notion case study Vendor Hold back a test set that never feeds training, which prevents reward hacking.[2][2] Shopify Engineering, Building production-ready agentic systems Primary

Calibrate every judge and publish the agreement. Write one narrow judge per failure mode.[18][18] Husain and Shankar, evals FAQ Secondary Measure each against expert labels with kappa or F1, and compare it with the agreement between two humans.[2][2] Shopify Engineering, Building production-ready agentic systems Primary Audit judges on a schedule, because models and traffic change.[1][1] GitHub, How we evaluate models for GitHub Copilot Primary

Gate on regression, with hard floors and one named decision owner. Set the gate as "no regression on the core suite against production". Add hard floors for safety and compliance tests that cannot trade against quality gains. Weigh quality and cost in the same decision, as Klarna's reversal shows.[42][42] Maginative, Klarna dials back AI customer service Secondary Write down who decides when metrics conflict, and use sequential tests for expert trials.[1][1] GitHub, How we evaluate models for GitHub Copilot Primary[8][8] Abridge, The science of AI evaluation Vendor

    • Put domain experts on labelling: Shopify uses product experts, Abridge licensed clinicians.[2][2] Shopify Engineering, Building production-ready agentic systems Primary[8][8] Abridge, The science of AI evaluation Vendor
    • Involve risk staff from the start, as ING did.[6][6] AI Expert Network, AI at ING Secondary
    • Keep an independent reviewer apart from the build team for high-impact uses; SR 26-2 and OMB M-25-21 both describe this role.[10][10] Federal Reserve, SR 26-2 attachment Primary[79][79] OMB M-25-21 (3 Apr 2025) Primary
    • Plan for a large share of engineering time: practitioners report 60–80% of development time on evaluation.[18][18] Husain and Shankar, evals FAQ Secondary

    Golden sets

    • Sample real production cases, not invented ones.
    • Start with hundreds of cases (ING 500 chats; Box 330 questions).[6][6] AI Expert Network, AI at ING Secondary[15][15] Braintrust, customer stories Vendor
    • Add each new production failure as a test.
    • Keep a separate frontier set for new capabilities, as Notion does.[17][17] Braintrust, Notion case study Vendor
    • Hold back a test set that never feeds training.[2][2] Shopify Engineering, Building production-ready agentic systems Primary

    Judges and their calibration

    • Write one narrow judge per failure mode.[18][18] Husain and Shankar, evals FAQ Secondary
    • Measure each judge against expert labels with kappa or F1.
    • Compare the judge with human-human agreement; Shopify used 0.69 as its ceiling.[2][2] Shopify Engineering, Building production-ready agentic systems Primary
    • Audit judges on a schedule.[1][1] GitHub, How we evaluate models for GitHub Copilot Primary
    • Publish agreement statistics with every result.

    User simulators

    • Use simulators for multi-turn products and agents.
    • Seed the simulator with real user goals, as Shopify does.[2][2] Shopify Engineering, Building production-ready agentic systems Primary
    • Treat simulator results as a pre-release screen; they do not replace real-user tests.
  • Release gates

    • "No regression on the core suite against production".
    • Hard floors for safety and compliance tests that do not trade against quality gains.
    • Quality and cost in the same decision.[42][42] Maginative, Klarna dials back AI customer service Secondary
    • A written decision owner for conflicting metrics.[1][1] GitHub, How we evaluate models for GitHub Copilot Primary
    • Sequential tests for expert trials, so a team can stop early with valid statistics.[8][8] Abridge, The science of AI evaluation Vendor

    Online monitoring and A/B tests

    • Roll out to staff first, then to a small share of users.[1][1] GitHub, How we evaluate models for GitHub Copilot Primary[6][6] AI Expert Network, AI at ING Secondary
    • Track behaviour signals such as accept rate, edits, resolution and escalation.[20][20] Cursor, Online RL for Tab Primary[8][8] Abridge, The science of AI evaluation Vendor
    • Run daily regression against the live model to catch silent provider changes.[1][1] GitHub, How we evaluate models for GitHub Copilot Primary

    • Fix metric definitions, and version them when they must change.[22][22] eesel.ai, Fin response quality Vendor
    • Monitor fairness metrics where decisions affect customers; EIOPA expects this for insurers.[11][11] EIOPA, Opinion on AI governance and risk management Primary

    Costs

    • Budget for expert labels, judge compute and engineering time; no survey gives a share of AI budget.
    • Run cheap deterministic checks on all traffic and expensive judges on samples.[18][18] Husain and Shankar, evals FAQ Secondary
    • Re-run the full suite on each new model release; Notion ships new frontier models within 24 hours because its suite runs fast.[17][17] Braintrust, Notion case study Vendor
    • The OpenAI Morgan Stanley page and the McKinsey ING page did not load; their content comes from search summaries.
    • No primary JPMorgan or Morgan Stanley document gives set sizes, judge use or thresholds.
    • No public eval detail for Goldman Sachs, Allianz, Zurich, Lemonade, KPMG, Epic or Ambience; Epic's open-source "Seismometer" was not checked.
    • No primary eval write-up from Duolingo, Stripe or Ramp.
    • Whether US bank regulators issued the planned request for information on AI.
    • The full ECB ML section, the EBA's 2023 report on ML in IRB models and New York's Circular Letter No. 7 (2024) were not read.
    • Whether the NAIC adopted its AI evaluation tool at the 2026 Fall National Meeting.
    • The PCCP guidance date (December 2024 or August 2025).
    • The Fierce Healthcare article of February 2026, the official MDCG 2025-6 text and the NY Comptroller's LL144 report could not be read.
    • Whether any 2026 OMB memo replaced M-25-21 or M-25-22.
    • Eval spend as a share of AI budget, eval headcount norms, and a systematic dataset of enterprise eval failures.
