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

Anthropic released two new AI models, Claude Fable 5.2 and Mythos 5.2, priced 20% below OpenAI's GPT-6 Astra as the industry's price war intensifies. The company claims both models deliver superior performance at lower cost, positioning them as direct competitors to OpenAI's flagship offering. The launch comes as Anthropic moves toward an initial public offering, making pricing strategy and market share gains critical to its valuation story. The debut underscores mounting pressure on AI developers to compete on cost as well as capability. Investors will watch adoption metrics and enterprise uptake for the new models, along with any retaliatory pricing moves from OpenAI ahead of Anthropic's IPO.
