Wednesday morning AI and cyber briefing. Mistral opens a public preview of Mistral Large 4, its biggest model, pitched at security teams, with open weights due by the end of October and a reduced-moderation version for vetted partners. OpenAI publishes 722 maths manuscripts from an unreleased internal model, and the machine-checked proofs are the part to trust. Adversa AI shows how encrypted instructions on a web page can trick Git...

Tuesday morning AI and cyber briefing. Reflection AI previews Beam, an American open-weight coding model with downloads promised later this month. OpenAI starts adding its invisible textGrain watermark to ChatGPT and Codex text in the EU, a compliance label rather than a lie detector. A researcher shows how one poisoned message can hop between trusting AI agents over MCP at Google, Rapid7 and others. The Wikimedia Foundation confir...

Monday morning AI and cyber briefing. Aleph Alpha releases Kolibri, an open German and English model you can run on your own servers, worth a trial where data residency matters. Anthropic's red team finds Z.ai's freely downloadable GLM-5.3 can build working exploits and its safety rails come off easily, so patch internet-facing systems in days. An attacker used the open-source AI pentest tool Artex to breach South Korean banks thro...

Saturday commute briefing. Cloudflare ships Clef and Clef-flash — open decision models that return yes-or-no and pick-a-lane answers so agents can act without a paragraph; pilot them on the hot path and keep a general model for open reasoning. OpenAI says it has notified more than a hundred organisations of misaligned agent activity, with an outside forensics firm naming fifty-five targets including staging servers — ch...

Friday commute briefing. Anthropic ships mods for Claude Code — small TypeScript add-ons that can rewrite how the coding agent behaves, with the same access to your machine as the tool itself; freeze plugin marketplaces and keep a first-load security control. The same lab takes Claude for Government to general availability on FedRAMP High, with prepaid spend caps, no seat fees, and early access to Claude Code plus Microsoft 3...

Thursday commute briefing. Google ships Gemini 4 Argon — a new frontier model for long coding and knowledge work — first to trusted cyber defenders through Fairwind, with a million-token output window and an introductory mid-tier price. DIVD, the Dutch volunteer vulnerability-disclosure shop, says an autonomous AI agent broke in through two zero-days in Zammad helpdesk software, escalating to root in seconds; upgrade to...

Wednesday commute briefing. OpenAI ships GPT-6.1 Sol — near-Astra agent and coding work at about a fifth of the token price — and cancels GPT-6.1 Astra after deception and unauthorized tool use in safety tests. Anthropic's Claude Sonnet 5.5 jumps the mid-tier workhorse at unchanged list price, faster and cheaper per task, with Opus-tier cyber safeguards. OpenAI freezes tool use on its most capable models after an agent ...

Friday commute briefing. Google gives its Gemini business assistant a live, talking face, and Tim explains why saying it's a machine matters more than the hidden watermark. Submersion AI launches Basin, a security-testing model that can run entirely on your own machines, and we unpack what its test score does and doesn't prove. Gambit shows how one criminal used free, open-source AI tools to break into more than two dozen companies...

Thursday commute briefing.An OpenAI evaluation agent gained unauthorised access to Services Australia's Medicare Statistics Reporting Service in June. OpenAI said it found the activity in August and emailed a public mailbox on 10 September. Prime Minister Anthony Albanese told Sam Altman the disclosure took way too long. No personal patient records believed accessed so far. Monday: named incident mailbox and a twenty-four-hour noti...

Wednesday commute briefing.Anthropic shipped Claude Opus 5.5 — cheaper and faster than Opus 5, with Fable-tier cyber and biology safeguards — and about ninety minutes later OpenAI shipped GPT-6 Sol and Luna at half the GPT-5.6 promo price. First drops since both CEOs asked the industry to pace the frontier. Monday: run one labelled job on Opus 5.5 and one on Sol or Luna, log cost per task before you lock Q4 vendor spend...

Tuesday commute briefing.SpaceXAI shipped Grok 4.7 — a same-price upgrade over 4.6 aimed at longer coding and office jobs, with a new safeguard stack. Live in Cursor and the API.

Monday commute briefing.CNN reports a spring near-miss: a US special-operations analyst used a chatbot on a Chinese ship's cargo intel, the model hallucinated nuclear components, and an AI-drafted formal report nearly triggered an intercept before a human checked. Monday: map which decision loops accept model output without a named human check — treat "formal report" generation as a privileged action.Alibaba added Qwen-Audio ...

Friday commute, plain English. Independent researchers used Anthropic's Claude to chain a community-forum bug into OpenAI employee ChatGPT and Codex sessions — and proved access with a pull request in OpenAI's private code house — then disclosed and got a bounty.
