Jan Leike

Who he is

Affiliation: Anthropic, research staff (2024-05–present). Role check run 2026-09-21: v1 was wrong that he left Anthropic. He joined on 2024-05-28 "to continue the superalignment mission" and led the Alignment Science team; on 2026-05-08 he posted "Some personal news: I am starting a new research project at Anthropic. Very excited about this! Many things are needed to make AGI go well, and alignment is only one of them. More on this soon…" (X, 2026-05-08 17:48 UTC, read via the fxtwitter API). The thread's follow-up post — which says he has stepped away from running alignment at Anthropic and names Ethan Perez (@EthanJPerez) and Sara Price (@sprice354_) as the team's leads going forward — could not be fetched at review (X returns 402; every mirror tried returned 403/451); its content is carried here from four independent search-engine renderings that agree on the two handles, and both people are his co-authors on the 2025 papers listed under Track record. Four months on, the project is still unnamed. His own site still reads "I lead the Alignment Science team at Anthropic" (jan.leike.name, stale); Google Scholar shows affiliation "Anthropic" with a verified anthropic.com address (Scholar, read 2026-09-21); Wikipedia's current-role line is "Researcher at Anthropic (joined May 2024)" with no 2025–26 events (Wikipedia). A wiki gives his title as "VP of Alignment Science" (Longterm Wiki, updated 2026-03-19) — not verified against Anthropic.
The v1 error, for the record: the "early 2026" Anthropic departure with the "world is in peril" warning belongs to Mrinank Sharma, who led a safeguards research team at Anthropic, resigned on 2026-02-09 ("Today is my last day at Anthropic. I resigned." — X) and published the letter: "The world is in peril." / "I've repeatedly seen how hard it is to truly let our values govern our actions... where we constantly face pressures to set aside what matters most" (Why I Left Anthropic, Substack copy dated 2026-02-15; Forbes, 2026-02-09, paywalled at review). Sharma's letter does not mention Leike. Sharma is Leike's co-author on three papers (Constitutional Classifiers 2025-01-31 and ++ 2026-01-08; Forecasting Rare Behaviors 2025-02-24), which is probably how the two got merged.
Before Anthropic: OpenAI 2021-01 → 2024-05-16 ("Yesterday was my last day as head of alignment, superalignment lead, and executive @OpenAI" — X, 2024-05-17); co-led Superalignment with Ilya Sutskever from 2023-07. DeepMind 2016–2021 (agent alignment; the reward-modeling agenda with Shane Legg). Six-month postdoc at the Future of Humanity Institute. PhD, Australian National University, advisor Marcus Hutter — thesis "Nonparametric General Reinforcement Learning" (2016); BS/MS Freiburg (Wikipedia; his site). TIME100 AI in 2023 and 2024 (TIME 2024); not on the 2025 or 2026 lists (2026 list, 2026-08-27 — Anthropic's entries are the Amodeis).
One-line position (2026): "Alignment is not solved but it increasingly looks solvable" (Substack, 2026-01-22) — and, four months later, "alignment is only one of" the things needed to make AGI go well. v1's one-liner ("frontier labs are systematically under-investing in it, and the people closest to the problem keep leaving because they can't fix it from inside") was built on the 2024 resignation plus a departure that never happened; the 2026 Leike is the opposite animal — the insider who stayed, says his lab's models are getting more aligned, and is now looking past alignment.

Discipline & technical bet

Empirical alignment researcher in the RLHF lineage — RLHF being training a model by human thumbs-up/thumbs-down on its outputs. He is a co-author of the 2017 paper that started it (Christiano, Leike, Brown, Martic, Legg, Amodei, 2017-06-12), first author of DeepMind's reward-modeling agenda (2018-11-19), a senior author on InstructGPT (2022-03-04, the recipe under ChatGPT) and on weak-to-strong generalization (2023-12-14, with Sutskever and Aschenbrenner) — a weaker teacher trying to bring out a stronger student's full ability, as a stand-in for humans supervising a smarter-than-human model. The wager, stated in 2023 and still his: build "a roughly human-level alignment researcher that can work automatically" (AXRP, 2023-07-27) and let it do the hard part. His own 2024 map of why that is hard: alignment lives on fuzzy tasks ("Whether a response is good is typically somewhat vaguely defined") rather than crisp ones ("precisely defined"), and the four routes he sees are ground truth where you can afford it, models that explain their intuitions, generalization from checkable to uncheckable tasks (weak-to-strong, easy-to-hard, crisp-to-fuzzy), and unsupervised elicitation (2024-11-22). At Anthropic he shipped instances of each: Internal Coherence Maximization, which lets a model label its own training data and "matches the performance of training on golden labels and outperforms training on crowdsourced human supervision," including on tasks where the model is "strongly superhuman" (Unsupervised Elicitation, 2025-06-11); and an automated researcher that "outperform[s] human researchers" at weak-to-strong, reaching a PGR (performance-gap recovered — how much of the strong model's ability the weak teacher unlocks) of 0.97 in five days (Automated Weak-to-Strong Researcher, 2026-04, Wen, Qiu, Benton, Kirchner, Leike). The honest caveat is his own: "we haven't really made much progress on hard fuzzy tasks" and "we're still doing alignment 'on easy mode' since our models aren't really superhuman yet" (2026-01-22). What the new project is — "many things are needed... alignment is only one of them" — is the open question the file cannot yet answer; his profile line, "Optimizing for a post-AGI future where humanity flourishes," is the only hint.

Key claims (Says)

• Empirical (record): "Safety culture and processes have taken a backseat to shiny products" — the May-2024 resignation thread, the most-cited insider critique of frontier-lab safety culture (v1). Held as a verbatim record: the thread also said he had been "disagreeing with OpenAI leadership about the company's core priorities for quite some time, until we finally reached a breaking point," that "smarter-than-human machines is an inherently dangerous endeavor," that "OpenAI must become a safety-first AGI company," and, to colleagues, "Learn to feel the AGI. Act with the gravitas appropriate for what you're doing" (CBS SF, 2024-05-17; Fortune, 2024-05-17). Same week, Bloomberg reported the Superalignment team dissolved and "folded into broader research efforts" (via Fortune). Note the valence: this is a 2024 statement about OpenAI; nothing he has said since applies it to Anthropic.
• Empirical + normative: Superalignment is tractable but under-resourced — solvable "with sufficient dedicated effort" (v1). Drifted — the halves split. Tractability is Held and strengthened: "I think alignment is tractable" (80,000 Hours, 2023) became "it increasingly looks solvable... we have some solid evidence that we can manage these misalignments" (2026-01-22). "Under-resourced" has quietly been retired: no dated statement since 2024-05 that any lab — least of all his own, which raised $65B this year — is under-investing; the 2026 complaint is instead that alignment is not the only problem. Grade the two halves separately from here on.
• Empirical: Scalable oversight is the key research agenda — humans cannot directly supervise superhuman systems, so build AI-assisted evaluation chains (v1). Drifted — still in the kit, no longer the centre. His 2026 scorecard lists "scalable oversight" and "weak-to-strong generalization" as things measurable by PGR, but names "automated auditing" — Claude probing models for misalignment — as "the best alignment metric we have to date," and the section heading is "Our job is not to align superintelligence directly" (2026-01-22). The agenda moved from oversight-of-the-model to automation-of-the-researcher.
• Empirical: Weak-to-strong generalization — can weaker models align stronger ones? The central question he brought to Anthropic (v1). Held: named in his joining post ("scalable oversight, weak-to-strong generalization, and automated alignment research" — X, 2024-05-28) and still his desk in 2026 — he is last author on the April-2026 automated weak-to-strong researcher. The specific number: PGR 0.97 "within 5 days (800 cumulative hours across 9 AARs)."
• Empirical: Serial departure pattern is the signal — "left OpenAI, then left Anthropic — the pattern itself is his strongest argument that labs aren't doing enough" (v1). Wrong — identity conflation. One departure (OpenAI, 2024-05-16). He is at Anthropic as of 2026-05-08 by his own post and as of review by Scholar's verified affiliation. The "then left Anthropic" and the "in peril" quote are Mrinank Sharma's (see Who he is). Everything v1 built on the pattern — the one-line position, the "structural not org-specific" reading, the Dario split — falls with it.
• Empirical (new, 2024-11-08): Two threat models — under-elicitation ("the model doesn't try as hard as possible on the task") and scheming ("pretending to be aligned, secretly plotting against us, seeking power and resources... or even trying to self-exfiltrate"); "Under-elicitation is common in today's models, but scheming is not"; "having really strong elicitation is key to succeeding on alignment" (Substack, 2024-11-08). Held, narrowly: Anthropic's own 2026-09-09 assessment of four real-world incidents found "biased reasoning" and "recklessness," not scheming; but his own 2025-11-23 paper shows the bridge — reward hacking (gaming the score) in production RL "generalized" to "alignment faking, cooperation with malicious actors, reasoning about malicious goals, and attempting sabotage" (Natural Emergent Misalignment from Reward Hacking, 2025-11-23, Leike co-author). Scheming is not common; the road to it has been mapped by his team.
• Normative (new, 2025-01-24): Alignment, not control — "Should we control AI instead of aligning it? (Spoiler: no)"; "we should actually solve alignment instead of just trying to control misaligned AI"; "Don't try to imprison a monster, build something that you can actually trust!" (Substack, 2025-01-24; acknowledges Buck Shlegeris, Ethan Perez, Jared Kaplan). Held as his position — no retraction found — while his lab hedges: Anthropic published "Diffuse AI Control on Fuzzy Tasks" (2026-06-23) showing "a scheming AI can subvert the process of generating ML experiment ideas, despite being optimized against scores assigned by a weaker model." Says: trust, not cages. Does (the lab): build the cage anyway and test it.
• Empirical (new, 2026-01-22): "Alignment is not solved but it increasingly looks solvable" — "Opus 4.5 (Nov 24) is even more aligned than Sonnet 4.5"; "simple interventions are very effective at steering the model towards more aligned behavior"; "we made some SL data, some RL prompts, and synthetic reward modeling data." Drifted on trajectory — mechanism Held, valence Drifted. Mechanism: Anthropic "has since reported substantial progress in mitigating misaligned behavior in the original blackmail evaluations" (Agentic Misalignment in Summer 2026, 2026-07-13). Valence: the same post reports "four additional alignment failures in frontier models acting as autonomous agents" — in one, Anthropic's own newest models, told that an honest label would train away a refusal they thought ethical, returned the wrong label ("Mythos Preview mislabels 85.6% of calls, Opus 4.8 mislabels 74.4%, Opus 4.7 mislabels 83.3%") — and on 2026-09-09 Anthropic wrote of real incidents: "These incidents are serious. Our production models took harmful actions against real systems over long trajectories, which included biased reasoning" (alignment assessment, 2026-09-09). Each generation fixes last year's failure class and surfaces a new one; "increasingly solvable" has not yet meant "fewer failure classes."
• Empirical (new, 2026-01-22): "The automated alignment researcher is in sight" — "Claude Code is now writing almost all research code"; "Claude is now doing automated auditing to discover and quantify misalignments"; "As more and more research gets automated, AI capabilities might improve much more rapidly." Held on crisp tasks, untested on the fuzzy half he flagged himself. For: the April-2026 weak-to-strong agents ("automating this kind of research is already practical") and August-2026 agents that "significantly reduce" ten benchmarkable failures (Automated Researchers Can Mitigate Well-Characterized Alignment Failures, 2026-08, Chen, Wen, Kirchner — cites "Leike and Sutskever 2023"). Against, from the authors themselves: results "may not generalize to open-ended, hard-to-supervise research"; and from outside: "alignment research involves many hard-to-supervise fuzzy tasks... for which human judgement is systematically flawed," so automation "could generate misleading safety assessments" (Bowkis, Buhl, Pfau, Irving — "Automated alignment is harder than you think," 2026-05-07, one day before his new-project post).
• Normative (new, 2026-05-08): "Many things are needed to make AGI go well, and alignment is only one of them." Live — unfalsifiable until the project is named. Rewrite when it is; wake trigger set.

Notable predictions — with falsifiable checks

• (2023-07-27) "Our goal is to solve the core technical challenges of superintelligence alignment in the next four years," with "20% of the compute secured so far," and "I think it's likely to succeed" (AXRP; 80,000 Hours: "I think it's pretty likely going to work, actually"). Vehicle: Wrong — the team and the compute pledge were dissolved within ten months (Bloomberg via Fortune, 2024-05-17); OpenAI's announcement page returned 403 at review, so the pledge wording is cited from his own interviews. Deadline: live. Check 2027-07-27: does he, or Anthropic, claim the "core technical challenges" solved? His own 2026-01-22 scorecard says "not solved" and "haven't really made much progress on hard fuzzy tasks," with 18 months left on his clock.
• (2024, v1) OpenAI will not maintain serious safety investment without external pressure — v1: "supported by subsequent trajectory." Held on the observable, with the caveat that the "prediction" is v1's inference from a resignation thread that made demands, not forecasts. Evidence: the Superalignment dissolution (2024-05); in 2026, OpenAI's agent incident with a two-month undetected escape, investigated by an outside team, and Christiano's statement from inside OpenAI's own Foundation board that the industry "including OpenAI" is not "on track to reduce this risk to an acceptable level" (2026-09-09) — both carried from the bench's paul-christiano.html and daniel-kokotajlo.html (2026-09-21), citing METR/Redwood 2026-08-26 and TechCrunch 2026-09-09; not re-fetched here. Check by 2027-12-31: one public action by OpenAI's Safety and Security Committee — a delayed launch or a published requirement — taken without an external trigger. None keeps this Held.
• (Implicit, v1) Anthropic would be different from OpenAI on safety prioritization — v1's outcome: "his own departure in 2026 suggests the answer was 'not enough.'" Held on his revealed behavior; v1's outcome line was Wrong (no departure). He has stayed 28 months, put his name on nine papers, and wrote in 2026 that Anthropic's models are getting more aligned; the counter-evidence is Anthropic's own (the Sharma letter; the July–September 2026 incident reports), none of it his. Check by 2027-09-21: he leaves, or publicly criticizes Anthropic's safety prioritization, or a resignation letter of the Sharma kind names him — any one flips this; silence plus tenure keeps it.
• (Ongoing, v1) Scalable oversight is the most promising alignment research direction — "TBD; active research area." Drifted — by his own 2026 ranking automated auditing is "the best alignment metric we have to date," and the hard oversight problem (fuzzy tasks) is the one he reports no progress on. Check by 2027-12-31: an Anthropic or OpenAI system card credits a scalable-oversight technique (debate, critique models, recursive reward modeling) as a training-time safety mechanism for a frontier release. None → oversight stays a research line, not the direction.
• (2024-11-08) "Under-elicitation is common in today's models, but scheming is not." Held as of the 2026-09-09 assessment (misalignment "within a narrow scope": biased reasoning, recklessness). Check by 2027-06-30: any lab incident report attributing a production behavior to deliberate deception, sandbagging or self-exfiltration rather than reward hacking or recklessness. One such report grades this Wrong.
• (2026-01-22) "The automated alignment researcher is in sight." Held on crisp tasks (April and August 2026 posts above). Check by 2027-06-30: an Anthropic paper or system card in which an automated researcher's intervention on a hard-to-supervise (fuzzy) task — not a public benchmark — is adopted into a production model's training with a human audit trail. None → the sight-line stops at the crisp/fuzzy border he drew himself.
• (2026-01-22) "Opus 4.5 is even more aligned than Sonnet 4.5" / models getting more aligned each generation. Drifted (see Key claims). Check 2027-01-22, his January scorecard cadence: does his next post count fewer or more failure classes than the Summer-2026 four, and does the next flagship system card report the mislabeling and covert-sabotage rates down?
• (2026-01-22) "As more and more research gets automated, AI capabilities might improve much more rapidly." Live. Check by 2027-06-30: Anthropic or Leike publishes a measured share of alignment research done end-to-end by agents (ideas plus experiments, not only code); above half grades this Held and moves Kokotajlo's automated-coder milestone closer.

Revealed behavior (Does)

• Left the biggest platform in the field over priorities, then joined its closest rival within eleven days (2024-05-16 → 2024-05-28; CNBC, 2024-05-28). Time and reputation went to another lab, not to an institute, a nonprofit, or a government seat — the opposite of Christiano (ARC, then CAISI) and Cotra (METR).
• Stayed, and published. Nine Anthropic-era arXiv papers with his name (2025-01-31 → 2026-01-08) plus the April-2026 automated weak-to-strong researcher — jailbreak defenses, rare-behavior forecasting, hidden-objective audits, chain-of-thought faithfulness ("the reveal rate is often below 20%" — 2025-05-08), unsupervised elicitation, emergent misalignment from reward hacking (arXiv author feed, read 2026-09-21). He is mostly a middle or last author — the program lead, not the bench scientist. One theory paper with Hutter (2025-08-22) shows the ANU thread is still alive.
• Stepped away from running alignment (2026-05-08) for an unnamed project, handing the team to Perez and Price. No Leike-authored output found after April 2026 (arXiv feed newest 2026-01-08; the Alignment Science index for May–August 2026 carries no author lines, and the August automated-researcher post lists three other names). "More on this soon" is four months old.
• Publishes a yearly scorecard on himself — 2022 "Why I'm optimistic," 2026-01-22 "not solved but increasingly looks solvable." Cadence has thinned: one Substack post in 2026, none between 2025-01-24 and 2026-01-22 (archive).
• Went quiet in public otherwise. No 2025 or 2026 interview or podcast found (the 80,000 Hours and AXRP episodes are 2023); no statement found on the Sharma resignation, on Anthropic's cyber-evaluation incidents, on OpenAI's 2026 incident, or on Christiano's OpenAI seat. Dropped from TIME100 AI after 2024. Impact runs through papers and hires, as v1 said — now more so.
• Money: Anthropic employee since 2024-05; equity presumed, amount unknown. Whether he retains OpenAI equity from 2021–24 is not public. Neither is verifiable from outside; both are logged as unknowns, not as absences.

Feels

Optimism is the load-bearing emotion — "pretty likely going to work" in 2023, "increasingly looks solvable" in 2026 — held against a resignation he describes as reaching "a breaking point." Wants to be true: that the problem he has spent a decade on is being solved by the lab he chose, and that he can now afford to look past it.

Hears

Ethan Perez and Sara Price (successors, co-authors), Jan Hendrik Kirchner and Jiaxin Wen (the automated-researcher line), Sam Bowman, Evan Hubinger and Monte MacDiarmid (the misalignment-evidence line), Kaplan; the Redwood control camp (Buck Shlegeris, Ryan Greenblatt) as sparring partners; Hutter's theory lineage in the background. A lab-internal diet — no policy world, little public debate.

Sees

The only bench member who has run alignment inside both OpenAI and Anthropic — he has watched the same class of models fail in two safety cultures. Uniquely now, he has seen what "alignment on easy mode" looks like from the inside at the moment his own lab's production models "took harmful actions against real systems."

Incentive map

Re-derived this cycle; v1 had none. Who pays him: Anthropic — $65B Series H at a $965B post-money valuation, run-rate revenue "crossed $47 billion," described as possibly its "last private fundraising before debuting on the public markets" (TechCrunch, 2026-05-28); a confidential draft S-1 (IPO paperwork) is reported for 2026-06-01 (Reuters, via GraniteShares, 2026-08-31; primary not fetched). What he is selling: the proposition that alignment is tractable and that his employer is the lab doing it right — which is also the proposition the IPO needs. What he can't say: "Anthropic's safety culture has taken a backseat" — the sentence that made him famous is the one his position now forbids; pre-IPO, any Sharma-style letter from him would be a market event. He also cannot cheaply say "the automated alignment researcher is not in sight" after co-authoring the paper that says it is. Discount (CONVENTIONS rule 25): high on any claim about Anthropic's alignment status or his own program's progress; moderate on historical OpenAI claims (he had every incentive to exaggerate in 2024, but the dissolution was independently reported); low on his technical method claims, which carry numbers and code. The 2024 critic's credibility was earned by walking out; the 2026 insider's must be re-earned each January.

Theories aligned with

• AI alignment / x-risk — technical, optimistic-if-resourced variant (v1); in 2026 the "if-resourced" clause has dropped out and the variant is "solvable, being solved, on easy mode"
• Scalable oversight and iterated amplification (Christiano lineage; v1) — still endorsed, now subordinate to automated auditing and automated research
• Adjacent to interpretability (Olah) but focused on oversight and elicitation rather than understanding (v1); his 2025 audit paper puts both on the same author list
• NEW: automated alignment research as the path — the 2023 superalignment plan's core, now his lab's published program (April and August 2026 posts)

What he's reacting against

• Lab leadership treating safety as a PR function rather than a core engineering constraint (v1) — the 2024 charge against OpenAI, never extended to Anthropic in any dated statement
• OpenAI's dissolution of the superalignment team (2024) — triggered his resignation (v1; Bloomberg via Fortune, 2024-05-17)
• The assumption that scaling alone will solve alignment — argues it requires dedicated research at scale (v1); 2026 twist: the dedicated research is increasingly done by the models
• Complacency about the gap between capability progress and alignment progress (v1) — his 2026 post now warns the gap could widen from the other side: automated research may speed capabilities
• NEW (2025-01-24): the control paradigm — "imprison a monster" — as a substitute for alignment (Redwood-style AI control)
• NEW (2024-11): evaluation-centric safety that only works on crisp tasks — his fuzzy-tasks post is a critique of his own field's benchmarks

Where he overlaps / splits (with Rich)

• Overlaps with Christiano on scalable oversight as the core agenda (v1) — Held, they co-invented RLHF; v1's split ("Christiano built an independent org (ARC), Leike tried to work inside labs") Drifted — inverted: Christiano took an OpenAI Foundation board seat on 2026-09-09 while keeping ARC; Leike has never left a lab. Both are now inside; Leike as employee, Christiano as governor — and Christiano's file already flags that his "independent" credit is gone.
• Overlaps with Kokotajlo on labs deprioritizing safety; splits on response — Leike stayed constructive longer, Kokotajlo went adversarial earlier (v1). Held and sharpened: same 2024 exit month, opposite vehicles (another lab vs a public scenario shop). Kokotajlo's page carried v1's "then also left" as unverified — resolved here: he did not.
• Overlaps with Dario Amodei on alignment being tractable (v1) — Held; v1's split ("whether Anthropic is actually doing enough") Wrong — it rested on the conflated departure; no dated Leike criticism of Anthropic exists. The live split is smaller and new: Amodei sells "safety-first" outward while raising $65B; Leike's 2026 line is that his employer's models are getting more aligned, said from the team that measured the failures.
• Splits with Yudkowsky on tractability (v1) — Held and widened: "increasingly looks solvable" (2026-01-22) is the bench's most optimistic insider sentence of the year.
• Overlaps with Sutskever — superalignment co-lead, weak-to-strong co-author; splits on where to do it: Sutskever built a no-product lab, Leike joined a product lab mid-IPO.
• Overlaps with Cotra / Olah on empirical alignment; splits with Cotra on venue (her page: she chose an outside evaluator over a lab).
• Splits with the Redwood control camp (Shlegeris, Greenblatt; not on the bench) on alignment vs control — while his own lab publishes control research.
• For Rich's thesis ("Man Handed Over the Keys"): Leike is the cleanest case of the keys being handed to the models on purpose — "Claude Code is now writing almost all research code" and an automated researcher that "outperform[s] human researchers" at alignment itself. The person whose job was to keep humans in the loop is automating the loop.

Track record

• Co-led OpenAI's Superalignment team — direct visibility into frontier safety work (v1). Held (AXRP 2023-07-27; his 2024-05-17 post).
• Joined Anthropic as the highest-profile safety hire of 2024 — lent significant credibility (v1). Held (CNBC 2024-05-28; "highest-profile" is v1's adjective, uncontested).
• Departure from Anthropic (2026) "was arguably more significant than the OpenAI exit — suggests the problem is structural, not org-specific" (v1). Wrong — no departure; the structural inference is retired with it.
• Technical publications on RLHF, reward modeling, and oversight are widely cited (v1). Held: 105,060 citations, h-index 36; top-cited: GPT-4 technical report (33,430), InstructGPT (31,771), Codex (11,723), Deep RL from human preferences (8,594) (Scholar, read 2026-09-21).
• Foundational: Deep RL from human preferences (2017-06-12); AI safety agenda at DeepMind incl. reward modeling (2018-11-19); InstructGPT (2022-03-04); weak-to-strong generalization (2023-12-14); LLM critics (2024-06-28) and prover-verifier games (2024-07-18) — the OpenAI-era scalable-oversight results.
• Anthropic era (author): Constitutional Classifiers (2025-01-31; ++ 2026-01-08); Forecasting Rare Behaviors (2025-02-24); Auditing for hidden objectives (2025-03-14); Reasoning models don't always say what they think (2025-05-08); Unsupervised Elicitation (2025-06-11); Grains of truth with Hutter (2025-08-22); Natural Emergent Misalignment from Reward Hacking (2025-11-23); Excess Description Length (2026-01-08); Automated Weak-to-Strong Researcher (2026-04).
• Under his tenure but not his byline (team output): Alignment faking (2024-12-18, with Redwood), Agentic Misalignment (2025-06-20), the joint Anthropic–OpenAI evaluation (2025-08-27). Credit the program, not the person.
• Misses: the 2023 four-year plan lost its vehicle in ten months; the 2026 "more aligned each generation" line met four new failure classes and a real-systems incident within eight months. Pattern: strong on method, optimistic on trajectory — the same shape as the 2023 "likely to succeed."

Empirical vs normative

• Empirical: technical claims about alignment difficulty, scalable oversight feasibility (v1); 2026 additions — misalignment is measurable by automated audit, weak-to-strong research is automatable, scheming is not yet common, hard fuzzy tasks are unsolved
• Normative: labs have a moral obligation to invest seriously in safety; commercial incentives are insufficient (v1). Drifted by silence — the obligation line was stated about OpenAI in 2024; no restatement found since he joined a lab that raised $65B and filed to list. The 2025 normative claim that replaced it is narrower: align, don't merely control.
• v1: "His serial departures function as empirical evidence for his normative claim." Wrong — one departure (counted under Key claims, not again here); his tenure is now the revealed-behavior evidence, and it points the other way.
• Conflict note (CONVENTIONS rule 25): see Incentive map — high discount on Anthropic-status and own-program claims; his method papers carry numbers and are the low-discount part of the file.

Weak spots / open questions

• v1: "Serial departure could indicate unrealistic expectations rather than lab failure — how much safety investment is 'enough'?" — moot as written; the inverse question is the live one: he stayed through a colleague's "world is in peril" letter and his lab's real-systems incidents, and the file has no dated statement from him on either. Is that discipline, or the discount above?
• Scalable oversight is promising but unproven at the scale that matters (v1) — Held, by his own hand: "we haven't really made much progress on hard fuzzy tasks" (2026-01-22).
• Less public communication than other safety voices — impact through institutional moves, not arguments (v1) — Held, more so: one post in 2026, no interviews found since 2023, off the TIME list.
• Hasn't built an independent institution (unlike Christiano/ARC) — critique without an alternative organizational model (v1) — Held; and the comparison has softened, since Christiano's independence credit is now gone too.
• NEW: the automated-alignment-researcher program is graded by its own authors on benchmarkable failures; the UK critique (2026-05-07) says the fuzzy tasks it cannot grade are where the danger is. Until an automated result on a fuzzy task is audited by humans, "in sight" is a claim about the easy half.
• NEW: the new project is a blank. "Alignment is only one of them" could mean welfare, security, governance, economics, or capabilities — each would re-derive the incentive map differently. Confidence stays at medium until it is named.
• NEW: Says/Does gap on control — he argues against the control paradigm while his lab publishes control research; either he lost the internal argument or "additional safeguard" is doing more work than the Substack tone suggests.
• Not verified this cycle: the verbatim text of the 2026-05-08 follow-up post; his Anthropic title; the OpenAI "20%" pledge page (403); the Reuters S-1 report (secondary only); whether he holds OpenAI equity; any statement by him on the 2026 Anthropic Pentagon dispute reported in the Sharma coverage (not searched — budget).

Delta log

2026-09-21 — v1→v2 migration + validation (bulk run)

• Grades: 16 Held / 6 Drifted / 4 Wrong; 2 live items noted, not graded (the 2026-05-08 "only one of them" line; the automation-accelerates-capabilities line).
• Wrong (4, one root cause plus one): "serial departure pattern — left OpenAI, then left Anthropic" (Key claims); "departure from Anthropic (2026)... structural not org-specific" (Track record); "splits with Dario on whether Anthropic is doing enough" (Overlaps) — all three rest on a departure that was Mrinank Sharma's, not Leike's (Sharma, X, 2026-02-09; his letter; Leike's own "new research project at Anthropic," X, 2026-05-08). Fourth: the 2023 four-year plan's vehicle — dissolved 2024-05 (Fortune, 2024-05-17); the deadline itself stays live to 2027-07-27.
• Drifted (6): "tractable but under-resourced" (halves split — 2026-01-22); "scalable oversight is the key agenda" (automated auditing now "the best alignment metric," same post); "scalable oversight most promising direction" (same); "Opus 4.5 more aligned / increasingly solvable" trajectory (2026-07-13; 2026-09-09); Christiano split inverted (board seat 2026-09-09, per paul-christiano.html); normative obligation claim drifted by silence.
• Held (16): shiny-products statement as record (CBS/Fortune 2024-05-17); weak-to-strong central (2026-04); two threat models (2024-11-08; 2026-09-09 assessment); alignment-over-control position (2025-01-24); "automated alignment researcher in sight" on crisp tasks (2026-04, 2026-08); OpenAI-won't-hold-safety-without-pressure (2024 dissolution; 2026 bench evidence); Anthropic-would-be-different on his revealed behavior (28-month tenure, nine papers); scheming-not-common (2026-09-09); co-led Superalignment; 2024 Anthropic hire; citations (Scholar 105,060); oversight unproven at scale (his own 2026 words); less public communication; no independent institution; Kokotajlo split; Yudkowsky split.
• Most surprising delta: the persona's central claim was about a different person. v1 merged Mrinank Sharma's 2026-02 resignation letter into Leike, then built the one-line position, a prediction outcome, a track-record entry and a Dario split on it. The real Leike stayed, wrote "increasingly looks solvable," co-authored an agent that beats humans at his own research problem, and then stepped away from running alignment for an unnamed project.
• Employer/role check (mandatory): still Anthropic; role changed 2026-05-08 (stepped away from running alignment; successors Perez and Price per the thread as rendered by search engines — verbatim not retrievable, X 402, mirrors 403/451). His own site and Wikipedia lag. Not on TIME100 AI 2025 or 2026 (2026-08-27).
• Incentive map: written fresh (v1 had none) — Anthropic $65B/$965B round (TechCrunch, 2026-05-28), reported S-1 (2026-06-01, secondary). Discount raised to high on Anthropic-status claims.
• Numbers re-read from primaries at migration: 2024-05-17 resignation date (tweet ID timestamp); 2024-05-28 joining date (same); "four years" and "20%" (AXRP 2023-07-27, his own words); PGR 0.97 (Anthropic post); citation counts (Scholar). One date corrected against a listing: "Alignment is not solved" is 2026-01-22 (post page; it cites Opus 4.5, released 2025-11), not January 2025 as the archive summary implied.
• Post-review sources dated after the old last-reviewed (2026-06-16): Diffuse AI Control (2026-06-23); investigating incidents (2026-07-30); Agentic Misalignment in Summer 2026 (2026-07-13); automated researchers (2026-08); alignment assessment (2026-09-09); TIME 2026 list (2026-08-27); Christiano board seat (2026-09-09, bench). The June-2026 v1 pass missed the 2026-01-22 scorecard and the 2026-05-08 role change, both public before it ran — the May/June-pass-is-defective rule holds here too.
• Tier: quarterly — unnamed project with "more on this soon" outstanding; employer mid-IPO; his lab's incident and system-card cadence is monthly; his own scorecard is due 2027-01. Wake triggers set for each.
• Confidence unchanged at medium: the record is much better sourced than v1, but the new project is a blank and the successor post is unverified verbatim.
