Anthropic Unveils New Fable, Mythos Models as Competition Heats up Ahead of IPO
- Anthropic released Claude Fable 5.2 and Claude Mythos 5.2, which the company says are designed to take on "daunting" technical challenges. This update marks the second major release for the Fable model class.
- The new models show improvements in coding, reasoning, and vision, generating outputs 30% faster than the 5.1 versions of the Fable and Mythos models. Additionally, testers noted the models communicate more clearly than their predecessors.
- Complex scientific capabilities include formalizing the proof of Fermat's Last Theorem in 30 hours; Anthropic noted the model "helped our engineers complete otherwise-infeasible software migrations" while orchestrating agent teams.
- Lowering Fable's cost from $10 to $8 per million input tokens, the company also provided enterprise clients access to zero data retention policies via the Enterprise Frontier Safeguards system.
- These releases follow a report from the assessment group METR, which suggested the lab might be approaching recursive self-improvement. Anthropic maintains Mythos 5.2 cannot act covertly against users despite stronger covert capabilities.
