Your AI now books, buys and sends.

This week: AI assistants moved from answering questions to doing the work. Meta's Muse is a personal agent that opens a browser, fills in forms and buys on your behalf in the US, while GPT-6 Astra and Gemini 3.8 Flash both aim at computer use and security tasks rather than chat, and ChatGPT Images 2.5 brings sharper editing to the tool most people already have open. Mistral's €3 billion raise is the counterweight: open-weight models for anyone who would rather not hand the whole job to someone else's agent.
