Elon's Grok Bot will use Claude | LAB 0017

Elon says his own bot will use Claude. plus Claude's new Haiku 5.5, monthly API credits for Max plans, GPT-6 in ChatGPT, and i test Haiku 5.5 against GPT-6 Luna on BuilderBench, live. the thesis: competition is great - builders are cashing in. the practical: i ran BuilderBench v3 on Haiku 5.5 and GPT-6 Luna (8 Oct 2026, 4 hours, extra high) and rated every job blind before i knew which model made it. GPT-6 Luna 44.58, Haiku 5.5 39.18 (out of 100, final personal scores, partial evidence). run cost estimates: Luna $1.47 (short-context scenario), Haiku $37.39 (provider-reported). these are API-equivalent estimates, not bills, and the methods differ. one run, my jobs, my taste. try it: pick three jobs you really do, give both models the same brief, and rate the work blind. thanks to today's sponsor, my software Threadify - your lead generation agent for Threads: https://www.threadify.app/home?utm_source=youtube&utm_medium=video&utm_campaign=lab-0017&utm_content=sponsor links Elon on Grok Bot's back-end models: https://x.com/elonmusk/status/2107724314451878104 xAI: Grok Bot now works with X: https://x.ai/news/grok-bot-and-x X API pricing: https://docs.x.com/x-api/getting-started/pricing Claude: introducing Claude Haiku 5.5: https://x.com/claudeai/status/2107894039626277339 Anthropic: Claude Haiku 5.5: https://www.anthropic.com/claude-haiku-5-5 Claude Devs: monthly API credits for Max and Team: https://x.com/ClaudeDevs/status/2107895957933408429 Claude help: monthly API credits: https://support.claude.com/en/articles/17154008-monthly-api-credits-for-max-and-team-plans OpenAI: GPT-6 and Intelligent UI in ChatGPT: https://x.com/OpenAI/status/2107894997538525580 Karpathy: ask for visuals, not text: https://x.com/karpathy/status/2105819303471976479 Tibo: day 3: https://x.com/thsottiaux/status/2107913674593644711 OpenAI help: ChatGPT Pro tiers: https://help.openai.com/en/articles/9793128-about-chatgpt-pro-tiers Theo: tsc-rs: https://x.com/theo/status/2107789940482621795 tsc-rs repo: https://github.com/pingdotgg/ts-rust want to sponsor a future episode of the LAB?
