A rolling page with the last seven days of AI briefings, in plain English. The weekly summary is on top; each day's full report is linked below. Updated every morning; days older than a week drop off.
This week at a glance
Four storylines ran through the week. Money: investors kept funding AI at enormous scale while starting to ask about returns - Anthropic's IPO filing showed $17 billion in quarterly revenue against about $895 billion in future compute commitments, OpenAI trimmed its next raise to $20 billion during an AI-spending selloff, China's Kling AI closed a ~$3 billion round, and inference startup Fal doubled to a $16 billion valuation on a $1.3 billion raise. Agents: software that does multi-step work kept moving into real products - Salesforce agreed to buy call-center voice-AI maker Cresta, DeepSeek open-sourced a prototype agent that manages other agents, Google set shutdown dates for its Jules coding agent, Tencent's new Hy4 learned to operate real software, and ChatGPT and Codex will share one usage allowance from December.
Rules and safety: the major labs agreed to honor one shared robots.txt switch letting websites opt out of AI training, OpenAI added teen protections and promised twice-yearly public safety reports, Canada announced up to C$1.6 billion for homegrown Cohere, and OpenAI readied a post-election policy push that includes rebranding data centers as "compute campuses." Products: Tencent launched Hy4 as the newest open-source heavyweight, Apple Intelligence finally got a China launch date with Alibaba's Qwen inside, Anthropic renamed its Claude plans and lifted a usage limit, Mistral released its largest model's weights for self-hosting, Google's research satellite answered its first prompt from orbit - and OpenAI said ChatGPT now handles a fifth as many searches as Google.
