Anthropic Launches Claude Fable 5.2 and Mythos 5.2 as IPO Roadshow Set to Begin
Read this in the Market Flux appAnthropic released two new frontier AI models, Claude Fable 5.2 and Claude Mythos 5.2, on Monday, positioning itself as a leader in AI development just as the company prepares for a closely watched public market debut. The launch marks the first frontier model release since CEO Dario Amodei publicly called for a slowdown in AI development, and comes as Anthropic made its IPO filing public, with a roadshow potentially beginning as soon as November 10 and a trading debut targeted for the week of November 16.
Fable 5.2 and Mythos 5.2 are priced at $8 per million input tokens and $40 per million output tokens, with an optional fast mode available at $16 per million input tokens and $80 per million output tokens. The models are up to 30% faster and 20% cheaper than their Fable 5.1 predecessors, and show improvements in coding, reasoning, and vision. Fable 5.2 outperforms the company's own Opus 5.5 on most benchmarks and tops competing models including GPT-6 Astra and Gemini 4 Carbon across the majority of tests, while matching Opus 5.5 Max at coding tasks at half the cost.
Scientific performance was a notable highlight: a network of 1,000 agents using the new models formalized a proof of Fermat's Last Theorem in 30 hours, and Mythos 5.2 correctly modeled 28 of 34 gene therapy capsids, underscoring its focus on life sciences applications. Mythos 5.2 availability is currently limited to organizations participating in Anthropic's Life Sciences program, while Fable 5.2 is broadly available across Anthropic's platforms today. Prediction markets on Kalshi place the probability of Anthropic officially announcing an IPO this month at 80 percent.
