Anthropic announces Claude Fable 5.2 and Mythos 5.2. Theye already solved black hole physics problems.
Claude Fable 5.2 and Mythos 5.2 have just been announced by Anthropic.
Anthropic introduced two new frontier AI models, Claude Fable 5.2 and Mythos 5.2, on Monday. These models are designed to address complex technical challenges and enhance performance in areas such as coding, reasoning, and vision. In the past few months, other leading tech companies like Google, OpenAI, and Meta have also released updated versions of their AI models, including Google Gemini 4 Carbon, Meta Muse Wonder, and OpenAI's GPT-6 Astra.
Upon its launch, Claude Fable 5.2 took the lead on the Artificial Analysis Intelligence leaderboard, previously held by Google's Gemini 4 Carbon. According to Anthropic, the new models topped pre-release tests, successfully designing three functioning electronic devices from scratch, solving two longstanding problems in black hole physics, and formalizing the proof of Fermat's Last Theorem within 30 hours.
Fable 5.2 and Mythos 5.2 also produce outputs 30% faster than their 5.1 versions and communicate more clearly than previous models. Pricing for the new models is more affordable, with inputs costing $8 per million tokens and outputs at $40 per million tokens. Fable 5.2 is now available to all Claude users, thanks to strong cybersecurity and biology safeguards that mitigate misuse risks.
Meanwhile, Mythos 5.2 is restricted to verified organizations focused on cybersecurity or biomedical research. Mashable suggests readers explore its Top Stories and Deals newsletters to stay informed about the latest tech developments.
