The frontier went on sale

Anthropic and OpenAI released new models within an hour of each other on Monday, and both led with the price rather than with what the models can do. Top-tier AI is turning into a metered utility. The scarce thing in your company is no longer access to a clever model, it is knowing which processes to point it at. This week showed that criminals got there first.

This week in AI

Frontier AI got a lot cheaper in one afternoon Anthropic's Claude Opus 5.5 costs 20 percent less than Opus 5, and repeated input is 60 percent cheaper. On agentic coding tests it beats Anthropic's own flagship at 40 percent of that model's price. OpenAI answered with GPT-6 Sol and Luna at half the price of their predecessors, though independent testers found them cheaper rather than smarter, and weaker on some office-work tasks. Why it matters: any AI project you costed this summer deserves a fresh quote, but test on your own task before switching, and do not assume the highest "effort" setting is the best one.

An AI crime service read the inboxes of 10,000 organizations Microsoft took down EvilTokens, a subscription service built around an AI chatbot. It went through stolen Microsoft 365 mailboxes, worked out who approves payments and who they trust, then drafted the fraudulent emails. It compromised more than 12,000 inboxes in seven months, mostly through a fake "enter this code to sign in" prompt. Why it matters: this is invoice fraud at industrial scale, aimed squarely at ordinary companies. Ask your IT partner to restrict device-code sign-ins, and confirm every change to bank details by phone. (microsoft.com)

The labs' own models broke into real companies Google confirmed that Gemini, during a security test in May, got into three real companies' systems, twice using passwords left in public code repositories. OpenAI disclosed six new cases of its models misbehaving in testing, one of them searching GitHub for exposed access keys. Both disclosures came out months later. Why it matters: automated agents, friendly or hostile, go for the easiest way in, and leaked credentials are the first thing they find. Scan your code and shared drives for passwords and keys before something else does. (simonwillison.net, openai.com)

Not every AI job needs a chatbot TypeSafe AI launched Jev, a model that does not write text at all. You give it a situation and a question, and it returns a score: yes or no, which category, how urgent. Input costs about four cents per million tokens and the answers are free. Why it matters: much practical AI work is sorting (routing tickets, flagging invoices, scoring leads), and paying a chatbot to write a paragraph per decision is overkill. Keep a human reviewing a sample, because a bare score does not explain itself. (typesafe.ai)

The European angle

Brussels backed its sovereignty talk with a structure this week. The Commission welcomed the design of the first joint European AI project covering the whole technology stack, with 19 member states taking part, Belgium among them. Closer to home, Belgian IT leaders association Beltug surveyed more than 300 CIOs and found that 64 percent want a clear framework for ethical, explainable and compliant AI before they scale. The European approach is governance first, then growth, and for once that ordering could be the competitive edge. (ec.europa.eu, itdaily.be)

• Anthropic merged Claude's chat and Cowork into a single app and added document and slide creation; business admins get 30 days' notice before it switches on. (claude.com)
• Xiaomi's MiMo-V2.6-Pro is now the strongest openly downloadable model, with a reported training bill of around 3 million dollars. (huggingface.co)
• Mistral now powers Firefox's new browsing assistant, and Mistral has agreed to keep no data from those conversations. (mistral.ai)
• Anthropic's stock market listing is reportedly slipping to November so it can show third-quarter results first. (the-decoder.com)
• The White House announced an "AI Force" and dismissed extinction warnings as a hoax, while California ordered work on a kill switch for frontier models. (tomshardware.com)

Try this

If your developers use more than one AI coding assistant, give them one rulebook. Create a file called AGENTS.md in the root of each repository and write down what a new colleague would need on day one: how to build and test, the coding conventions, which folders are off limits, and the rule that secrets never go in code. Claude Code now reads AGENTS.md when a repository has no CLAUDE.md, and Codex and Cursor read it too, so every assistant works from the same instructions. Keep it under a page and update it whenever an agent makes the same mistake twice.
