A busy day at the labs. Anthropic launched Fable 5.1 — with a restricted Mythos 5.1 variant — at sharply lower cache-read prices and a new enterprise safeguards story, which Devin quickly put numbers on. OpenAI published its pre-release safety write-up for the upcoming Astra model and shipped Epic integrations for ChatGPT for Healthcare, while Google DeepMind gave Gemini agentic video understanding. On the individual side, Simon Willison has a peek inside the Codex desktop runtime and a pointer to Graham Dumpleton’s new Python library.
