Briefings

Anthropic released Fable 5.2 and Mythos 5.2, marking the first major update to the Claude Fable series. The new model claims to solve two open problems in the physics of black holes, which is why it ranks first on Artificial Analysis. The user successfully ran prompts through the model, though high-level reasoning caused a token exhaustion error. Pricing dropped to $8/million input and $40/million output, a 20% discount from the previous version.
