Anthropic debuts Claude Fable, Mythos 5.2 models, priced 20% below OpenAI’s GPT-6 Astra

Anthropic has introduced Claude Fable 5.2 and Mythos 5.2, adding two models to its Claude product line as the company responds to OpenAI’s recently launched GPT-6 Astra.

The models were debuted on Monday. According to the supplied announcement, Anthropic has priced Claude Fable 5.2 and Mythos 5.2 at 20% below OpenAI’s GPT-6 Astra.

New models enter a closely watched AI market

The launch places Anthropic’s latest offerings directly alongside OpenAI’s GPT-6 Astra, which was introduced in early September. The timing makes the pricing comparison a central part of Anthropic’s announcement.

Beyond the model names and pricing difference, the supplied information does not detail the systems’ capabilities, availability, performance, intended users or commercial rollout plans.

Pricing becomes part of the model competition

By setting the new Claude models below GPT-6 Astra’s price, Anthropic is presenting them as a lower-cost alternative in the market for advanced artificial intelligence models. However, no further financial details or expected business impact were provided.

Anthropic’s announcement marks its latest disclosed response to OpenAI’s GPT-6 Astra launch. Additional information about Claude Fable 5.2 and Mythos 5.2 will be needed to assess how the models compare beyond pricing.
