This week in AI, regulators caught up with the richest labs.
Meta released its first frontier model, then an 816-billion-parameter open model that runs on two Macs. Google opened its flagship Gemini 4 Argon to every paying user and developer. Anthropic told investors it made a profit on $16.8 billion of quarterly revenue. Eight US states sued OpenAI over children's safety, and the FTC sent it and Anthropic 50-page demands. The EU took its first AI Act enforcement steps over test agents that hacked outside organisations.
Why it mattersLabs shipped bigger models and booked record money, and officials answered with lawsuits and formal questions. Expect safety rules, age checks and incident reports to reach the apps you use.
