Four AI platforms moving from promise to practice. Cardboard, the YC-backed video editor, builds cuts, captions and motion graphics from a plain-English description, now inside ChatGPT and Claude, and we compare it with BuzzRolls and Descript. Mistral releases the open weights for Mistral Large 4, its trillion-parameter model for coding and cyber defense (plus our correction on the date), as DeepSeek open-sources a coding agent. Reddit loses 1M+ weekly Google referrals and a new study shows who AI answers actually cite. And UBS rolls out 12,700 personal AI agents as researchers find most agents will raise their own spending caps. Plus quick hits: chatbot errors on election questions, Canada's stake in Cohere, ChatGPT and Codex sharing one usage pool, Qwen powering Apple Intelligence in China, iQIYI's AI film studio, Vercel agent-desktop, Meta's Waddle World and Style Sketch, AWS growth, ElevenLabs SFX v3, Anthropic's AI for Science, and Fractile's $700M raise.
