Claude Fable 5 & Mythos 5 were crazy, here's why :
- Both models supported a 1M token context window & 128K token outputs, largest limits in frontier AI
- Stripe reported, Fable 5 completed a migration across a 50M line codebase in a single day, that would take a team months
- Mythos 5 was so powerful in cybersecurity that its access was limited to only 200 vetted orgs including AWS, NVIDIA, Apple, Google & etc, in Project Glasswing
- It's safety systems triggered in less than 5% of sessions, meaning most users were interacting with near Mythos-level capabilities through Fable 5
