Anthropic’s Fable 5 model is the company’s most capable widely released Claude model. The company has also made it clear that it will also be its most expensive model with the most safeguards.

Anthropic launched Claude Fable 5 on Tuesday, a Mythos-class model with safeguards blocking cybersecurity and biology queries, priced at $10 per million input tokens.

It says new safeguards make it possible to release a Mythos-class model it previously said was too risky to make public.
