Anthropic just released the most capable AI model ever made available to the public — and most Scrum teams don't know it exists yet.

Yesterday, June 9, Anthropic launched Claude Fable 5. It's the first "Mythos-class" model the company has made publicly available. Until now, Mythos was restricted to a small group of government-approved cyberdefense partners. Now it's in your hands.

What makes it different? Fable 5 can work autonomously for days — not minutes. It can plan, delegate to sub-agents, check its own work, and iterate without human input at every step. Stripe reported it compressed months of engineering work into a single day on a 50-million-line codebase.

For Scrum teams, this isn't just a better chatbot. It's an agent that can take a Sprint backlog item and run with it. That changes what "done" looks like — and it changes what your team needs to know.

If you work in Scrum, Agile, or product development, understanding Fable 5 isn't optional. It's your next Sprint priority.
