Key Points

1Fable 5 is generally available
2Mythos 5 has restricted access
3Pricing is $10/$50 per million tokens
4Built for stronger professional work

Anthropic launched Claude Fable 5 for general use and offered the stronger Mythos 5 in restricted access. That lets teams use a capable model with safeguards in place, while keeping room for broader access in selected research and security settings.

What changed

Anthropic made Claude Fable 5 generally available and offered the related Claude Mythos 5 only to selected existing users and research settings. It also spelled out pricing and separated API versus subscription handling.

Why it matters

High-capability models are useful, but they also need safeguards against misuse. Anthropic is balancing broad availability with access controls tied to use case.

Impact for users

Developers can start with Fable 5 for normal work and consider Mythos-style access only where needed. Research and security teams may see access broaden over time.
