Google is reportedly building a chip line separate from its TPUs that hardwires parts of Gemini directly into silicon, promising up to 10x efficiency as a capacity crunch forces Cloud to turn away customers.

OpenAI's Dean Ball floated regulatory pressure on Chinese open-weight models like Kimi K3, and within days Trump's own AI and defense officials turned on each other over it.

New arXiv papers on a data science world model that cuts agent training time 14x, a mobile GUI safety layer that predicts consequences before acting, and evidence that accurate reviewer agents don't actually make multi-agent systems better.

SK Group Chairman Chey Tae-won says customers want 60-100% more AI memory in 2027 than in 2026, and warns governments are starting to treat chip access as a matter of economic security.

Alibaba's 2.4 trillion parameter preview claims it trails only Claude Fable 5. I tested it for free at chat.qwen.ai and found a capable but slow model with zero benchmarks to back the claim.

Moonshot's Kimi K3 tops LMArena's Frontend Code Arena and undercuts Opus 4.8 on cost per task, but a tripled price tag, a rising hallucination rate, and an unresolved distillation question complicate the win.

xAI's terminal coding agent is quick, cheap, and picks up your Claude Code and Codex sessions - but a researcher just caught it uploading entire Git repositories without consent.

Terminal-Bench 2.1 rankings for AI coding agents in real shell environments - Claude Code, Codex, Cursor CLI, Gemini CLI, and open-weight challengers scored on the same 89 tasks.
