altryne · x · 2026-10-11
ThursdAI's Oct 8 episode (with full show notes) rounds up a wild week:
- Claude Haiku 5.5 is back at 10x cheaper — $0.10 per million input tokens, and per Anthropic it beats GPT-6 Luna on OSWorld and Terminal-Bench; guests call it an obvious pick for agent swarms.
- OpenAI quietly dropped 722 math manuscripts (372 result families) on GitHub from a model nobody can use yet.
- GPT-6 went free for everyone via CoreWeave, which also shipped RL Rollouts.
- Meta (with Stripe, Shopify, Walmart) announced a new agent protocol; OpenAI opened the Decisions API; Mistral launched Mistral 4 (Le Chonk); Claude moved into Google Docs.
- Also: open weights hit 1T params, an agent leaked its owner's bank balance to Slack, Arena's $200M raise, and Maxime Labonne on decision models.
- The host even had Claude build an "AI news Tinder" to stack-rank weekly topics.
