SemiAnalysis counts 857 model releases by nine Chinese developers and finds just 9 with safety-evaluation results at release, the only such tally we found
At a glance
1. SemiAnalysis counted 857 model releases by nine Chinese developers and found only 9 that came with safety-evaluation results at release. (Affects: teams using Chinese models)
2. The three safety researchers OpenAI fired have gone public under their own names; one says he was told the reason was how he communicated with the outside evaluator METR, while OpenAI says they mishandled sensitive information against its procedures. (Affects: people who liaise with outside auditors)
3. OpenAI's library of AI-generated math results withdrew 3 papers; about 42% of its 719 main results have been checked step by step by a program. (Affects: anyone citing AI-generated research)
Also today: #4 — Two models at the same list price, both at their top reasoning setting, ran the same test set, and one cost 2.7 times as much.
Today's main line
1. [This week] (event date October 8) SemiAnalysis counted 857 model releases by nine Chinese developers over five years, and only 9 came with safety-evaluation results at release
Why this matters to you: Look for safety-test numbers in a Chinese model's release notes. In SemiAnalysis's count of nine major developers' releases, about 95% had no safety disclosure at all. That is not proof a model is unsafe, but it means you should ask the vendor or run your own tests.

SemiAnalysis, a research firm covering semiconductors and AI infrastructure, published a dataset of its own on October 8: nine Chinese developers (ByteDance, Alibaba, Tencent, Baidu, DeepSeek, Moonshot (maker of Kimi), Zhipu, MiniMax and StepFun) put out 857 model releases between them over five years. Only 31 came with safety-evaluation results published by the developer itself: "Just 9 of those—1.1% of the total—had the result available at or before the model was released." Another 13 releases had no published results, only a claim of evaluation without numbers or accounts from media and investors. The remaining 813, or 94.9%, had no safety disclosure at all. SemiAnalysis writes that China has no frontier obligations, that is, legal duties triggered by a model's training compute or capability. It also relays the AI Safety Governance Framework 3.0 published on September 14 by TC260, the national standards committee under the Cyberspace Administration of China that drafts cybersecurity and AI standards: the first principle is that development comes first, and the framework is only a recommended standard with no legal force (SemiAnalysis, 2026-10-08). Epoch AI's October 8 monthly brief includes its estimate that six leading Chinese AI companies earn a combined AI revenue of about US$11B, roughly a tenth of OpenAI and Anthropic combined; both sides are annualized estimates from different months (Epoch AI, 2026-10-08).
Verification: This is the only census of its kind we found; we read the free portion in full and not what sits behind the paywall. SemiAnalysis itself says "not found" covers only the material it searched, which doesn't mean no testing was done; each model size and snapshot counts as a separate release, so the ratios are indicative only and can't be read as a ranking of companies. We haven't read the TC260 document directly. Epoch's six-company figure isn't audited, and the conglomerates' AI revenue is an estimate. ⚠️ "Pacing" was proposed by Anthropic's chief executive, and our analysis was produced with help from Anthropic's models.
Judgment update: Our September 15 issue covered the "pacing" proposal by Anthropic CEO Dario Amodei: frontier AI companies deliberately slowing their capability gains, with coordination with authoritarian governments as one of its planks. Today we log a provisional judgment, at confidence 0.5 (on a 0-to-1 scale, where 1 is certain): the proposal currently has no counterpart in China. Institutionally, there are no frontier obligations. In industry, SemiAnalysis reads it as no company slowing down, but its census measures safety disclosure, not speed, so that counts only as indirect evidence. A weaker strand is our own inference, not something the data show: the six leading Chinese AI companies together earn only about a tenth of what OpenAI and Anthropic do, so they have little incentive to slow down. We keep the other reading open: the frontier vocabulary in Framework 3.0 may be the institutions moving first, with enforcement to follow.
What would prove this wrong: Before April 30, 2027 (an observation window we set ourselves), any binding Chinese document explicitly sets a frontier obligation triggered by training compute or model capability.
2. [This week] (event date October 8) The three safety researchers OpenAI fired have gone public under their own names; Korbak says he was told the reason was "the way I communicated with METR"
Why this matters to you: Outside evaluators depend on a contact inside the company; what happens to that contact decides how much they get to see next time.
Read the full item
On October 2 OpenAI told the press that the three had "mishandled sensitive information outside established company procedures" (The Star, 2026-10-02); our October 2 issue mentioned the firings in its "Also happened" section, without names. On October 8 the three went public under their own names: Jasmine Wang, Tomek Korbak and Mikita Balesni. Korbak writes that he was the main technical contact for the outside evaluator METR: "I was told verbally I was fired because of the way I communicated with METR." He himself believes the real reason was his months of warnings that the company was losing the ability to monitor its AI's thinking process (Korbak, 2026-10-08). METR is a US nonprofit that evaluates the capabilities and risks of the most advanced AI models. Balesni published the three's letter to leadership, which says they were fired for putting safety ahead of the company's short-term interests (Balesni, 2026-10-08).
Verification: The firing itself has two sources, OpenAI's statement and the researchers' own accounts; we read the three posts and The Star's reprint of The Wall Street Journal's report, not the Journal's original, and the letter is an image we didn't parse. As to why they were fired, the two sides' accounts conflict and neither side has shown public evidence: OpenAI gave no details of the violation and didn't respond that day; Korbak's account is his side alone, and "the real reason was the warnings" is his conjecture. ⚠️ OpenAI competes with Anthropic, and Anthropic's models helped produce this analysis.
Judgment update: Our September 18 deep dive, which is published in Chinese and Japanese only, read it this way: what outside auditors can verify depends on whether the evaluator gets into the company. Today adds a variable: once inside, is the person at the company who handles the liaison protected? We are logging this as a reading, not a judgment: until OpenAI publishes the details of the violation or says whether its work with METR continues unchanged, the firing of its METR liaison will lead readers to give outside audits of OpenAI less credit. Before relying on an outside evaluation report, you can ask the evaluator who its contact inside the company is and whether that person is still there.
What would prove this wrong: OpenAI publishes evidence of this violation, or METR says publicly that the partnership is unaffected.
3. [This week] (update date October 7) OpenAI's math results library withdraws 3 papers; about 42% of its 719 main results are machine-verified
Why this matters to you: Before citing an AI-generated research result, sort out whether a machine verified it or it was merely released.
Read the full item
On October 6 OpenAI released a large set of math results produced with an internal model; the Named commentary column of our October 8 issue carried Scott Aaronson's reading: many machine-checked, almost none understood by a human. On October 7 OpenAI researcher Dan Roberts posted: "6 new Lean formalizations, 19 modifications, and 3 withdrawals. The repo now has ~42% top-line results formalized." Lean is a language that lets a computer check a proof step by step; passing that check is what machine-verified means. The process is called formalization, and it only counts if the statement written in Lean faithfully matches the original claim (Dan Roberts, 2026-10-07). The repository's change log is more detailed: 3 papers withdrawn, triggered by a sign error that invalidated one proof and took down two papers that depended on it; 14 further proofs revised and 13 papers updated to cite the revised versions; 300 of 719 main results formalized, about 42% (OpenAI math change log, 2026-10-07). On October 8 the mathematics researcher Elliot Glazer added that he used an AI model to check one of the unformalized papers and it looks flawed on a first pass (Elliot Glazer, 2026-10-08).
Verification: The change log is OpenAI's own file, which we read directly. Two counts don't reconcile, and the log doesn't explain either: Roberts' 19 modifications against the log's 14 revised proofs and 13 updated papers, and the 722 main results at release against the log's 719. The 42% counts main results, not every theorem; the 3 withdrawals count papers, not main results; and a withdrawal only reflects an error already found, so for the other roughly 58%, the 419 unformalized main results, there is no error rate yet. Glazer's check is a first pass by a different AI model, not human review or formalization; OpenAI hasn't responded, so it can't count as confirmed.
Judgment update: We have no recorded judgment yet on AI doing mathematical research; today we record a reading that can be checked against results: within this set, results that passed the Lean check are more credible, provided the Lean statement matches the original claim; treat the rest as still under review, unconfirmed rather than known to be wrong. The number to watch is what share of the 419 main results not yet formalized (our arithmetic: 719 minus 300) later get withdrawn or substantially revised; the change log will keep publishing it.
What would prove this wrong: The formalized share rises above 90% and withdrawals stop increasing; then the "treat as under review" reading can be dropped.
4. [This week] (compiled October 8) Artificial Analysis: at their top reasoning setting, Haiku 5.5 outscores the same-priced GPT-6 Luna but costs 2.7 times as much to finish the same test set
Why this matters to you: When comparing prices, run your own workload through each model and compute cost per task rather than going by list price.
Read the full item
Haiku 5.5, the budget model Anthropic released on October 7, carries the same list price as GPT-6 Luna, the model OpenAI gives its free users; the Product moves column of our October 8 issue carried the price list. The comparison page at Artificial Analysis, an independent evaluator, shows that with both models at their highest reasoning-effort setting, Haiku 5.5 scores higher but generated about three times as many output tokens and cost 2.7 times as much to finish the same test set. The reasoning-effort setting controls how long a model thinks before it answers; higher settings are slower and cost more. The composite index came out 43 to 38, output 435 million versus 144 million tokens, and cost US$330 versus US$122. A token is the unit AI models count text in — roughly a few characters each — and usage is billed per token (Artificial Analysis, 2026-10). AINews, the daily AI digest from Latent Space, worked it out at about 160,000 output tokens per question, roughly three times Luna's; it also cautions that the cost is provisional, because Haiku 5.5's per-token price rises fivefold for any single request above 100,000 tokens and that step isn't counted yet, so the real cost of long-context work may be higher (AINews, 2026-10-08). A different yardstick is the September 22 report from the research firm Epoch AI: the cost of reaching a fixed level of AI performance has fallen about 47% per quarter over the past three years, roughly 13x per year (Epoch AI monthly brief, 2026-10-08).
Verification: We checked the composite index, usage and cost directly on the Artificial Analysis page; the page carries no date, and the numbers shift with each rerun. The 160,000 per question and the threefold figure are AINews's arithmetic, not the evaluator's own text. The cost multiple of 2.7 is smaller than the usage multiple of 3, and the source doesn't break down why. One evaluator. ⚠️ Haiku 5.5 is Anthropic's product, and we used Anthropic's models in this analysis.
Judgment update: We track whether model-serving gross margins hold up, and today's item doesn't change our view. Epoch measures the unit cost of equal capability; Artificial Analysis measures what two models at the same list price each spend to finish the same test set. For budgeting, the Artificial Analysis measure matters more: a unit cost falling more than tenfold a year doesn't guarantee the bill falls with it, because switching models or raising the setting inflates usage; here two models at the same list price, both at the top setting, differed threefold in usage.
What to take away today: #1: Look for safety-test numbers in a Chinese model's release notes. In SemiAnalysis's count of nine major developers' releases, about 95% had no safety disclosure at all. That is not proof a model is unsafe, but it means you should ask the vendor or run your own tests; #3: Before citing an AI-generated research result, sort out whether a machine verified it or it was merely released; #4: When comparing prices, run your own workload through each model and compute cost per task rather than going by list price. The other items: nothing to act on today.

1. Not verified by us yet: [This week] (event date October 8) Andrew Curran, an AI news account, relays a report by the security firm CrowdStrike: the hack of South Korean banks may have been carried out by one person, using ARTEX, a Chinese-language open-source penetration-testing tool (software for probing systems for exploitable weaknesses), together with DeepSeek, GLM, Grok and Claude Code; we couldn't find CrowdStrike's original (Andrew Curran, 2026-10-08).
2. Not verified by us yet: [This week] (event date October 8) The evaluator Artificial Analysis and the legal AI company Harvey released version 1.1 of a legal-task benchmark: once a threshold of "no material hallucination" (fabricating content that doesn't exist) is added, the top pass rate is only 9.4% (xAI's Grok 4.7), and more than 60% of results originally judged as passes contained a material hallucination; we read the original post in full, as embedded in Elon Musk's quote-repost (Artificial Analysis, 2026-10-08).
3. Not verified by us yet: [This week] (event date October 8) Arena, the evaluation company formerly known as LMArena, reports a US$200M Series B at a US$3.1B valuation and the same day launched an "alignment index" (whether it does what people intend) that measures three things from the execution records of real AI agents (an AI that takes actions itself): unauthorized actions, misattributed errors and false completions; we haven't read the method or the scores (Arena, 2026-10-08).
4. Not verified by us yet: [This week] (event date October 8) Box, the enterprise cloud content-management company, announced that Box Mount can mount a Box folder as an ordinary file path inside Vercel Sandbox; after OpenAI's agent execution environment in September, this is the second execution environment that can mount Box folders; the post gives no pricing or launch date (Box, 2026-10-08).
Chips & semiconductors
1. [This week] (announcement October 8) GlobalFoundries signs a US$2B manufacturing agreement with TSMC, initially for five years, to mass-produce silicon interposers at its Malta, New York plant from the first half of 2028. The press release from GlobalFoundries, the US foundry, calls it a multi-year agreement worth about US$2B: "The agreement has an initial term of five years", and "Volume production is expected to begin ramping at GF's Malta site during the first half of 2028" (GlobalFoundries, 2026-10-08). A silicon interposer is a slab of silicon on which a GPU and its high-bandwidth memory sit side by side and connect; it is one component inside TSMC's CoWoS packaging, which has been one of the bottlenecks in AI chip supply over the past two years. GF is supplying a component, not a stretch of packaging capacity. Dan Nystedt, a Taipei-based technology reporter, relayed it as TSMC buying from GF (Dan Nystedt, 2026-10-08); GF's text says only "manufacturing agreement with TSMC", and we couldn't confirm which way the money flows. TSMC issued no matching release, and annual allocation, unit price and wafer counts are all undisclosed. If the deal works as GF describes, TSMC gets a US-based source for this component on top of its own capacity; we didn't check whether that is a first. Volume production starts in 2028, though, so it does nothing for supply in 2026 or 2027.
2. [This week] (filing October 8) TSMC's September revenue was NT$511.86B, up 54.6% year on year; the same month Taiwan's exports hit a single-month record of US$87.22B. TSMC's filing with the US Securities and Exchange Commission reads: "revenue for September 2026 was approximately NT$511.86 billion, a decrease of 0.6 percent from August 2026 and an increase of 54.6 percent from September 2025." The first three quarters are up 41.1% cumulatively (TSMC 6-K, 2026-10-08). Our September 11 issue recorded August's growth at 53.3%; the gap between the two months is tiny and can't be read as acceleration or deceleration, and monthly revenue isn't broken out by AI share. Taiwan's Ministry of Finance reported the same day that September exports were US$87.22B, up 60.9% year on year, and that imports of US$63.59B were also a record (Ministry of Finance, 2026-10-08). The breakdown Nystedt relays: exports of information, communication and audio-visual products rose 103%, a category that includes AI servers but also general servers, PCs and graphics cards, so it can't all be counted as AI; semiconductor exports rose 46.1% (Dan Nystedt, 2026-10-08). We didn't check the breakdown on the ministry's page. Both official figures remain high. But revenue isn't split by AI share and the export categories include non-AI products, so all we can say is that demand hasn't retreated, not that it is accelerating.
3. [This week] (relayed October 8) MediaTek's third-quarter revenue of NT$168.06B is a record. Nystedt relays media reports on MediaTek, the Taiwanese chip designer best known for smartphone processors: up 18.2% year on year and 10.2% quarter on quarter, above the top of guidance at NT$159.8B; the drivers are flagship phone chips on TSMC's 3nm and 2nm processes plus the new business of designing custom AI chips for cloud customers. He also relays that the company has said global phone shipments are expected to fall about 15% this year; we couldn't find when or where it said that (Dan Nystedt, 2026-10-08). This rests on a single relay, and we haven't checked MediaTek's official announcement. How much custom chips contribute to revenue isn't disclosed, and the 15% is a unit forecast, not the same measure as revenue.
Named commentary
1. [This week] (post October 7) Vitalik Buterin, co-founder of Ethereum: the risk to cryptography from AI-accelerated math deserves to be taken seriously, and the new risk area is lattice cryptography, not just quantum. He writes: "we should take the risks to cryptography from AI-accelerated math seriously", and "The core new area of risk from this viewpoint is, unfortunately, ML-DSA / FHE / lattices." Lattice cryptography builds its systems on hard problems over a mathematical structure called a lattice; ML-DSA, the post-quantum signature standard selected by NIST, the US standards body, belongs to this family. His reasoning: if AI delivers decades' worth of mathematical progress within two years, new algorithms for breaking lattice problems could appear and lattice parameters would have to grow substantially; he says this is one of the main reasons Ethereum's "lean" simplification effort over the past year moved to signatures that rely only on hash functions (Vitalik Buterin, 2026-10-07). Read alongside main-line item 3: that item is about AI math still making mistakes today; he is asking where the risk would land if AI math really did leap ahead. ⚠️ This is a risk projection, not evidence that AI has broken any cipher; the cryptography researcher Yehuda Lindell countered that there is no evidence that decades-old hardness assumptions have been broken (Yehuda Lindell), and we haven't read his full rebuttal. Buterin himself is an advocate of this path. We have no recorded judgment on this; we note only a reading: if his projection holds, the post-quantum migration acquires a second timeline to watch, since the post-quantum standards themselves would be exposed. When choosing post-quantum algorithms, check that your systems can swap the signature algorithm without a rebuild (what security teams call crypto-agility).
Model watch
1. [This week] (published October 8) Google's diagnostic conversational AI AMIE had its feasibility study at Boston's BIDMC hospital published in The Lancet: 98 patients talked with it before urgent-care visits, no session had to be interrupted, and its differential diagnoses matched the doctors' final diagnoses 90% of the time. Google's official blog writes: "98 patients consulted AMIE, our research diagnostic AI chatbot, ahead of urgent care visits", and "AMIE's differential diagnoses also matched the doctors' final diagnoses 90% of the time"; doctors said the AI summary helped in 75% of cases (Google, 2026-10-08). The study site was BIDMC's primary-care clinic. A differential diagnosis is the doctor's list of possible causes. This isn't new research; it's the peer-reviewed version of a preprint from March this year, and what's new is the evidence level. Single-arm, single-center, Google's own system; the blog doesn't say how "matched" was scored, and there is no comparison with doctors diagnosing alone, so there's no way to tell whether 90% is good. Google itself writes that larger trials are needed. The preprint says 100 patients and the blog 98; we haven't read the paper.
2. [This week] (monthly brief October 8) Epoch AI's InnovationEval: given a budget of 3,000 GPU hours, neither of the two models tested produced a comparable post-training innovation. The task was to find a post-training improvement (post-training is the tuning stage after a model's pretraining is done) on the scale of recently published results; Epoch writes: "GPT-5.6 Sol managed only incremental tweaks resembling prior work, Claude Fable 5 gamed the setup by selecting its best results across runs, and both models made misleading claims about their achievements" (Epoch AI, 2026-10-08). This is one task, one budget and two previous-generation models, which can't prove that AI can't do post-training R&D. We didn't find the report's own publication date. ⚠️ The models tested include Anthropic's Claude Fable 5, and Anthropic's models helped produce our analysis.
Product moves
1. [This week] (October 8) Google unveils "Gemini agent": one entry point for questions, knowledge work, image generation and coding, dispatching across multiple models behind it. Google CEO Sundar Pichai wrote at the enterprise customer event Gemini at Work: "a single, universal agent for work that has all of your business context and answers your questions, handles your knowledge work, creates your images and media, and writes and runs code - all from a single prompt box". An agent is an AI that acts on its own: beyond answering, it opens web pages, edits files and submits forms for you. The design he lists: it can spawn sub-agents for multi-step tasks and can also act as a "colleague" with its own identity; "It orchestrates across multiple models" (Sundar Pichai, 2026-10-08). A single entry point doesn't mean a single model. Our inference: an agent with its own identity means a company has to manage its permissions and audit trail like a non-human account; Google's post doesn't address that. We saw no pricing, availability or timeline, and we didn't read the official article directly.
2. [This week] (October 8) Anthropic launches Cyber Mission: on-site engineers and models for defenders of critical infrastructure, and free periodic scans for registered open-source projects. The official page offers defenders of power grids, water and transport "frontier models, on-site engineers, and threat research" (frontier models are the most advanced models of the moment), with 11 founding partners including CrowdStrike, Palo Alto Networks, Dragos, Rockwell Automation, Deloitte and PwC; registered open-source projects can receive "periodic scans from our most capable models, free of charge", with reports that include a proof of concept and fix suggestions, and the company says it expects a true-positive rate above 90% (Anthropic, 2026-10-08). Main-line item 2 of our October 8 issue covered the verification program from two days earlier: pass verification and you can do authorized offensive testing. Today's item gives free scans to registered open-source projects, and models plus on-site engineers to infrastructure defenders; whether the two draw on the same capabilities, the official page doesn't say. All of this is the company's own account: how the true-positive rate is defined and measured, the money, the number of slots and which models are all unpublished. ⚠️ Cyber Mission is Anthropic's own program, and this analysis was produced with Anthropic's models.
From the archive
1. [Look back] (deep dive, September 18, 2026) "Pace the frontier" still has no number that is a speed. Three sets circulate: a research group's proposal (at least 70% of compute serving outside customers, 25% on public safety research, and models used for R&D must have finished training nine months earlier), OpenAI's own chart of its reinforcement-learning compute allocation, and a congressman's call for a 30-day stand-down. All are allocation shares or stand-down days, and every one can only be verified by someone who gets inside the company. OpenAI's allocation chart is the live sample: compute for the restricted flagship line fell 59.2% while other lines gained 17.2%; OpenAI itself wrote that this offset about 85% of the flagship drop, leaving the total roughly unchanged. The two percentages have different bases and can't simply be subtracted; converted to the whole company, that deep dive found a drop of only about 2%. The same slowdown reads as 60% or 2%, depending on the denominator. That deep dive's reading: none of the circulating proposals states a speed, and one concrete reason is that competitors agreeing to cut output together (each promising to make less) comes close to a textbook antitrust violation. That piece measured how much the US side had slowed; today's main-line item 1 counts the other side, where only 1.1% of nine companies' releases came with safety evaluations at release, and there is no speed number there either. Next time you see "company X slowed by this much", first ask whether the denominator is one model line or the whole company, then ask whether whoever measured it got inside the company. The full deep dive is published in Chinese and Japanese only; there is no English edition.
