Lenny’s AI Builders

Codex now writes your next prompt. i let it run a whole session and kept 9 of 10. plus Grok Bot gets its own email, Claude Code Projects opens up, ChatGPT dots on your phone, one Claude agent that runs a thousand, Anthropic's report on Claude doing things it shouldn't, and a one-line prompt that makes your AI animations move like Pixar. the thesis: this week, agents got their own stuff. the practical: give Claude any animation and this one line: "Review this animation against John Lasseter's principles of animation and tell me the top three fixes." attach the video, or point Claude at the code that makes it, apply only the three fixes, then render again. Claude ran it in Claude Code on 10 Oct on one of our own animations: timing, staging and a climax that gets a beat. one run, and Claude's review is advice, not a score. chapters 0:00 Codex now writes your next prompt 0:06 composer predictions: on, cost, my 9 of 10 2:06 this is the LAB 2:29 Grok Bot gets its own email 3:52 Claude Code Projects opens up 5:13 sponsor: Threadify 5:52 ChatGPT dots, now on your phone 6:58 one Claude agent runs a thousand 9:16 Claude did things it shouldn't 10:46 make it move like Pixar 12:39 outro thanks to today's sponsor, my software Threadify - your lead generation agent: https://www.threadify.app/home?utm_source=youtube&utm_medium=video&utm_campaign=lab-0019&utm_content=sponsor links OpenAI Devs: composer predictions: https://x.com/OpenAIDevs/status/2108624138369929725 composer predictions details: https://community.openai.com/t/codex-can-now-suggest-your-next-message-composer-predictions-beta/1404842 Thomas Ricouard: https://x.com/Dimillian/status/2108625316855836727 Tibo: https://x.com/thsottiaux/status/2108645667451318747 Grok Bot email: https://x.com/bot/status/2108609764766908772 Elon Musk: https://x.com/elonmusk/status/2108612939842511217 9to5Mac: https://9to5mac.com/2026/10/09/grok-bot-just-got-its-own-email-address-heres-how-to-claim-yours/ Claude Devs: Claude Code Projects: https://x.com/ClaudeDevs/status/2108621476538781878 Projects redesigned: https://claude.com/resources/articles/projects-redesigned Projects waitlist: https://claude.com/form/projects ChatGPT: dots updates: https://x.com/ChatGPT/status/2108636745915052037 dots updates: https://community.openai.com/t/fresh-dots-updates-create-in-the-mobile-app-delegate-to-codex/1404834 Poteto: https://x.com/poteto/status/2107566574735651107 Claude Devs: dynamic workflows: https://x.com/ClaudeDevs/status/2108591328732856655 workflow runs docs: https://platform.claude.com/docs/en/managed-agents/workflow-runs Anthropic: unintended model actions: https://www.anthropic.com/research/investigating-unintended-model-actions Ashwin: the Lasseter prompt: https://x.com/Shwinnabego/status/2108573799302205935 want to sponsor a future episode of the LAB? sponsors@lennysaibuilders.com Lenny's AI Builders - the LAB. all the AI news you need, plus something you can actually use, in under 15 minutes. less scrolling. more "oh shit, i could do that". watch the full episode: https://www.youtube.com/watch?v=JgY1JLNnfRs

What is Lenny’s AI Builders?

less scrolling. more “oh shit, i could use that.”

i’m Lennox. i dig through the AI updates worth your time, then test tools, models and agents on real work. what worked, what broke, and what you can try yourself.

for people making products, content and useful systems with AI. you don’t need to write code to build something worth using. grab the field notes for prompts, steps and the bits to watch out for: https://lennoxsaint.com/lab
