  "account": "On Monday, Anthropic introduced Claude Fable 5.2 and Mythos 5.2, the latest updates to its top-performing models. Fable 5.2 is available across multiple platforms, including AWS, Google Cloud, and Azure, while access to Mythos 5.2 is restricted to companies within Anthropic's Cyber and Life Sciences verification programs. Despite sharing the same underlying model, Fable 5.2 comes with enhanced cybersecurity and biology protections. Anthropic's press release downplays the naming change from 5.5, instead highlighting that Fable 5.2 is designed to handle the most difficult technical challenges, while Fable 5.1 and Mythos 5.1 are better suited for general coding and knowledge tasks. One of the key features emphasized by Anthropic is the speed of Fable 5.2 and Mythos 5.2, which generate output up to 30% faster than their predecessors. Additionally, a Fast mode, which accelerates token generation by up to 2.5 times, is now available for both models through various platforms and services. In terms of pricing, Fable 5.2 has been discounted from $10/$50 per million input/output tokens to $8/$40, while Mythos 5.2 retains the same rates. Notably, Fable 5.2 outperforms Opus 5.5 in certain benchmarks, such as FrontierCode 2.0 and FrontierSWE v2, while being comparable to Opus 5.5 in other evaluations. Despite these improvements, Anthropic notes that Opus 5.5 still leads in some specific tasks, such as AutomationBench and Elo measure of AA-Briefcase v1.1. Furthermore, Fable 5.2 is designed to minimize safety blocks, with early testing showing about 55% fewer interruptions overall, including about 60% fewer cybersecurity-related blocks. Enterprise customers can also leverage Claude Security, which includes Mythos 5.2, even if they are not part of the Cyber Verification Program. Anthropic is also introducing Enterprise Frontier Safeguards in private beta, which allows customers to retain data for 30 days for safety monitoring purposes.",
