Anthropic released Claude Fable 5.2 to the public and Mythos 5.2 to vetted organisations only. The models are reported as faster and cheaper than 5.1.
Anthropic unveiled new models called Fable 5.2 and Mythos 5.2 on 9 November 2026, as reported by ThePrint and LLM trackers, in the context of competition with OpenAI before Anthropic's expected IPO. Fable 5.2 is generally available. Mythos 5.2 is limited to vetted organisations, which get looser cyber and biology safeguards. The models are reported to be about 30% faster and 20% cheaper than version 5.1, priced at $8 per million input tokens and $40 per million output tokens. Separate reports say Anthropic has also secured power generator orders for its data centres and plans to go ahead with its IPO. The details of the IPO and the pricing are reported inconsistently across lower-quality sources, so they should be treated with caution. I could not open the ThePrint article, so the facts come from search summaries; the story's wider coverage includes Reuters and TechCrunch according to Techmeme headlines.
