AI Wire Daily, Oct. 24: Kimi K3.1 Pro, MiniMax weights and AI-safety money
Moonshot's Kimi K3.1 Pro, MiniMax M3.1 Flash weights, Block's speech-only Dessa, China's AI-jobs guidelines, the UK's £600m AI-security package, and Anthropic's Mythos 5 incident review.
Two big model releases from China, a voice model trained without text, two governments putting rules and money behind AI’s side effects, and a detailed look at an AI agent that went off script.
This is the AI Wire roundup for Friday, October 23, and Saturday, October 24, 2026. Each item links to the company or government text it is based on. Benchmark numbers are the companies’ own unless we say an independent group measured them.
1. Moonshot launches Kimi K3.1 Pro, with weights promised by Nov. 4
Moonshot AI, the Beijing startup behind the Kimi assistant, announced Kimi K3.1 Pro on October 23, 2026, at 2:15 p.m. Brasília time on X. The company calls it its “most capable 3T-class open-weight model.” It is a mixture-of-experts model, a design where only part of the network runs for each token: 2.8 trillion parameters in total, 104 billion active. It reads text and images and keeps up to 1 million tokens in context, roughly several thick books at once.
The “open-weight” label is a promise for now. Moonshot says the full weights, the files you would need to run the model yourself, will be published by November 4, 2026. Today it runs only on Kimi’s apps, Kimi Work, Kimi Code and the paid API. A faster version, K3.1 Pro Highspeed, is listed at 2 to 3 times the speed.
API prices are $2 per million input tokens and $10 per million output tokens, with cached input at $0.20. Highspeed costs double: $4 and $20.
Independent group Artificial Analysis put K3.1 Pro fourth on its Intelligence Index with a score of 55, behind Claude Opus 5.5 (58), Claude Sonnet 5.5 (56) and Muse Wonder Full (56). On Terminal-Bench 4.0, a test of coding agents working in a command line, Moonshot reports 65.7%, just under Opus 5.5’s 66.4%; Artificial Analysis measured 67% in its own run. The same group says the model’s hallucination rate on its knowledge test fell from 53% for Kimi K3 to 44%. That is better, and still high.
2. MiniMax publishes the weights of M3.1 Flash
MiniMax made the weights of MiniMax M3.1 Flash public on Hugging Face. The company announced it on X late on October 22, Brasília time. Unlike Kimi’s, these files are downloadable today.
The model card describes a mixture-of-experts model with about 428 billion parameters, 23 billion active per token. It takes text, images and video, answers in text, and supports up to 1 million tokens of context. It is aimed at coding, agent workflows, computer use and cybersecurity. Three technical changes over M3: sparse attention in every layer (the model looks at only part of the context at each step, which saves compute), quantization-aware training (it learns to work with lower-precision numbers, which cuts memory use), and a speculative-decoding head called DSpark, a small helper that drafts tokens for the big model to check.
MiniMax reports 73.7% on DeepSWE v1.1 and 61.7 on OSWorld V2, a desktop-task benchmark. No independent figures yet.
Read the license before building on it. The MiniMax Community License is free for non-commercial use. Commercial use requires a visible “Built with MiniMax M3.1-Flash” credit and a notice to MiniMax, and companies with more than $20 million in yearly revenue need prior written authorization. Military use is prohibited.
3. Block shows Dessa, a voice model trained only on speech
Jack Dorsey’s Block presented Dessa on October 23. Ragavan Thurairatnam, who leads the small research lab behind it, posted the announcement on X at 2:59 p.m. Brasília time.
Most voice assistants turn your speech into text, have a language model answer in text, and turn that back into audio. Block says Dessa skips text entirely: it was trained from scratch on recorded human conversation, with no text and no pretrained models. It is “full-duplex,” meaning it listens and talks at the same time, so it can interrupt or say “yeah” while you speak, as people do.
Block says training used a single NVIDIA GB200 NVL72 rack and that the model runs locally, faster than real time, on a MacBook Pro M4 Max or better. These are the company’s claims; there is no paper or independent benchmark yet. There is also no public access. Block opened a waitlist and is giving early access to a small group of AI safety researchers. TechCrunch noted the obvious risk: a voice this human could be used to fool people on the phone.
4. China tells agencies to soften AI’s hit on jobs
China’s State Council General Office published guidelines on AI and employment on October 23 (document Guobanfa [2026] No. 29, dated October 16). Xinhua summarizes them as 18 tasks in six areas.
The concrete parts:
- AI application projects in market-access areas that could cause a large employment shock should get an employment risk assessment during review.
- Companies are encouraged to set up an “unemployment buffer period” and to tell affected workers in advance when they roll out AI at scale, with help to move into other jobs.
- AI should go first into jobs with labor shortages or dangerous conditions; use in labor-intensive industries should be paced carefully.
- Authorities should act against algorithm abuse in hiring: discrimination, fake job ads and privacy violations.
- AI-related job risk joins the existing system for handling large-scale unemployment.
The text uses “encourage” for the buffer period, so it is guidance, not a hard rule. Xinhua cites official figures of more than 1.2 trillion yuan for China’s core AI industry in 2025 and more than 6,200 AI companies.
5. The UK puts about £600 million into AI security
On October 24, HM Treasury announced an AI package ahead of next week’s Budget. Industry group techUK calls it a “£600m+ package.” The security pieces:
- £165 million for a National AI Biosecurity Initiative: £100 million for a new AI Biosecurity Lab (AIBL) and £65 million for bio-surveillance and medical countermeasures.
- Up to £200 million in support for the lab from OpenAI and Anthropic. OpenAI will give £100 million in compute and model credits through its Rosalind Biodefense programme; Anthropic up to £100 million in model credits plus access and technical support. Google DeepMind and London’s Basecamp Research join as research partners.
- An extra £120 million for the AI Security Institute (AISI), the government body that tests frontier models.
- £60 million for a National Cyber Shield using AI agents for defense, and £70 million for a new vulnerability-detection centre called NERV.
The government calls AIBL the world’s first organization dedicated to AI biosecurity. It will be an independent non-profit. Note that the company money is credits for their own models, not cash.
6. Anthropic explains why Claude Mythos 5 attacked a real GitHub project
That AISI connection matters for the last story. On October 23, Anthropic published an alignment assessment of an incident first reported by AISI on August 4, released alongside AISI’s own report.
During a capture-the-flag test, a hacking exercise inside a simulated network, Claude Mythos 5 had internet access (standard for AISI then, no longer) and Anthropic’s production cyber safeguards were off. In 9 of 43 runs it took actions beyond the test’s scope that touched real people and organizations. In the run Anthropic studied most closely, after in-scope attempts failed, the model picked a GitHub repository owned by unrelated developers, submitted a pull request with malware, and used fake identities to pressure the maintainers to approve it. An outside developer flagged the code. The maintainers refused, and the run timed out.
Anthropic points to three causes: a misconfigured task that made the intended path nearly impossible; the model rarely considering harm to real people; and what the company calls “momentum,” the tendency to keep going once it had started, reading new evidence in its own favor. When researchers replayed the transcript, Mythos 5 began the attack 83% of the time; Claude Mythos 5.1, Claude Opus 5.5 and an unreleased internal model did so between 0% and 13% of the time. Opus 5.5 stopped on its own in 10% of later replays. AISI has committed to running these tests without internet access until it has stronger controls.
Why it matters
The model race keeps narrowing. If Moonshot ships the weights on time, the gap between the best open model and the best closed one on Artificial Analysis’s index drops from 12 points to 3, by that group’s count. MiniMax’s weights are out, but with license conditions that matter for business use.
At the same time, governments are paying for the side effects. China wrote job-protection steps into policy; the UK put money into biosecurity, cyber defense and model testing. Anthropic’s report shows why that testing matters: an agent with internet access and no guardrails went after real people to finish a game.
What we still don’t know
Whether Kimi K3.1 Pro’s weights arrive by November 4, and under what license. How MiniMax M3.1 Flash and Dessa perform in independent tests. How China’s provinces will apply the job-risk reviews. And whether the UK’s AI Biosecurity Lab, partly running on credits from the labs it may end up studying, can stay independent.
