Anthropic Releases Claude Fable 5.2 and Mythos 5.2

On Monday, November 10, 2026, Anthropic released two new models, Claude Fable 5.2 and Claude Mythos 5.2. According to The Verge, Anthropic said both models show improvements over the previous 5.1 generation in coding, reasoning, and vision capabilities, while also generating output faster. TechCrunch later covered the release as well, with content consistent with The Verge; TechCrunch's headline mentioned "Fable gets a price cut and speed boost," but the article did not give specific figures. Early that same day, the AWS Machine Learning Blog published first-hand news announcing that both models are now available on Amazon Bedrock and Claude Platform on AWS. A latest report from The Decoder filled in the previously missing pricing and performance details: Fable 5.2 pricing dropped from the previous generation's $10/$50 per million tokens to $8 for input and $40 for output, with output speed up to 30% faster; the report also said the release is intended to "regain the performance lead ahead of the IPO." With this, the previously undisclosed pricing details are now clear.
