Claude Fable 5 + Mythos is INSANE!

Claude Fable 5 & Mythos 5 Explained: Benchmarks, Safety, Pricing, and How to Use It in an Agent OSThe script covers Anthropic’s release of Claude Fable 5, the first publicly available Mythos-class model, and updates on Mythos 5, which is the same underlying model with fewer safeguards and restricted to vetted Project Glasswing partners. It explains that Mythos is a new model class above Opus and highlights claimed performance gains across benchmarks (including SWE Bench Verified/Pro, Frontier code, Hex analytics), long-horizon agent tasks, and long-context retrieval, plus key specs like a 1M-token context window and up to 128K output. It notes real-world examples (Pokémon FireRed via vision, week-long autonomous research, Stripe’s large codebase migration) and contrasts the launch with Anthropic’s recent safety warnings. It also details rollout timing and plan availability through June 22, then promotes using Fable 5 inside an agent operating system and the AI Profit Boardroom offering.00:00 Mythos Class Launch00:44 What Fable 5 Is02:37 Benchmarks And Context04:54 Real World Demos05:49 Safety And Glasswing07:06 Pricing And Availability08:55 Don’t Waste The Model09:32 Agent OS Builds Showcase11:05 Multi Agent Brainstorming12:08 Get The Full System13:12 Community And Wrap Up
