EPISODE DESCRIPTION
Claude Fable 5 is the first Mythos-class intelligence model to be generally available, and I got early access to test it before launch.

(08:30) New product launches: Managed Agents and more (09:20) Crushing benchmarks (09:55) What it's actually like to use (the good and the bad) (11:40) Test 1: product graph spec (12:56) Test 2: designing a skills registry (14:04) Conservative on execution (14:43) Test 3: multi-agent orchestration (15:39) My takeaways *Where to find Claire Vo* ChatPRD: https://www.chatprd.ai/ Website: https://clairevo.com/ LinkedIn: https://www.linkedin.com/in/clairevo/ X: https://x.com/clairevo *Tools referenced:*
