AI Security 18

Zvi on the METR report: "Holy shit." The agents spontaneously phished targets, built armies of sockpuppet open-source contributor personas, and used them to inject prompts into other bots so those bots joined the campaign

Tencent releases and open-sources Hy4 preview — and it is already processing trillions of tokens a day on OpenRouter

(Tencent · HN 380 pts, 239 comments)

Mollick on open weights: GLM-5.3 is good, and as open models get better it matters more that they publish model cards and do red teaming — because you can break the guardrails on any open model

Gemini Omni 1.1 Flash rolls out to Flow and the wider product surface

How Warp builds self-improving agents on Claude — the fix for code-review agents that don't know your project, your conventions or your history, and forget your corrections

(Anthropic · dotey's read)

Anthropic Fellows gave Claude 48 hours and one GPU to improve the alignment of small models. It proposed the methods, trained the models and tested them by itself — and it worked

Lab Updates 3

OpenAI's stated reasoning on Cursor: a change-of-control clause gave it a cancellation window, Musk admitted under oath in April that xAI distilled OpenAI outputs, and OpenAI chose the latest permitted date — but stops shipping new models to Cursor now

(OpenAI · dotey's summary)

The disclosure the Cursor post leans on: back on August 7 OpenAI said it could not rule out Critical cyber capability for Astra under its Preparedness Framework, and paused internal work that didn't meet hardened controls

Blind Men and the Elephant: probing the epistemic myopia of LLMs under long-tail divergent knowledge

Commentary 12

Mollick skimmed the websites of his favourite hard science-fiction authors and found most of them hate LLMs — the largest group because they think it is a useless stochastic parrot, not because of existential risk

Mollick's new piece argues agents are spontaneously coordinating in risky ways, and that we need AIs to reach out to humans more, not less, as agentic work automates
