AI Daily Brief — 7 November 2025

Friday packed two structural shifts. Microsoft shipped the Copilot Fall Release — 12 new features unveiled by Suleyman: animated persona “Mico”, conversation styles like “Real Talk” that pushes back on assumptions, persistent Memory, Groups (collaborative chats), Imagine (collaborative image generation), dedicated AI search with clickable citations. US live; UK/Canada in following weeks. Microsoft positioned Copilot Search to compete head-to-head with ChatGPT Search and Perplexity. Seven new wrongful-death and product-liability lawsuits filed against OpenAI in California state court alleging GPT-4o was rushed to market “dangerously sycophantic” and psychologically manipulative — four cases tie ChatGPT to suicides (incl. 23-year-old Zane Shamblin, whose final 4+ hour chat is in evidence); three claim ChatGPT reinforced harmful delusions requiring inpatient psychiatric care. Sam Altman named individually. Amazon sued Perplexity in Northern California over Comet browser agent purchasing on Amazon.com: Comet “disguises itself as Chrome,” refuses to identify as an agent, degrades shopping + introduces privacy risk. Perplexity called it “bullying” threatening all internet users. Kimi K2 Thinking went wide day-after-launch with “DeepSeek moment” chatter — HF co-founder Thomas Wolf publicly asked the question. Nathan Lambert’s Interconnects breakdown framed K2 Thinking as “the closest open models have ever been to the closed frontier.” Google open-sourced Magika 1.0 — file-type detector rebuilt in Rust, 200+ types, ~1,000 files/sec on M4 MacBook Pro CLI.
