Anthropic unveils two new AI models ahead of planned IPO

Anthropic on Monday unveiled two new artificial intelligence models, Claude Fable 5.2 and Claude Mythos 5.2, as the OpenAI rival seeks to strengthen its position in the growing AI market ahead of a planned initial public offering (IPO).

The company said Claude Fable 5.2 is designed for coding, reasoning and AI agent tasks, while Claude Mythos 5.2 is intended for approved cybersecurity and life-sciences research applications.

Access to Claude Mythos 5.2 will be restricted to organisations approved through Anthropic’s verification programmes for cybersecurity and life-sciences research. Claude Fable 5.2, meanwhile, will be available to a wider range of users.

Anthropic said the new models generate outputs up to 30 per cent faster than their Claude 5.1 predecessors and offer clearer communication with users.

The company has set prices at $8 per million input tokens and $40 per million output tokens, lower than the rates for previous Fable and Mythos releases.

The launch follows Anthropic’s introduction of Claude Haiku 5.5 in October, as the AI company expands its product range ahead of its planned IPO.

Competition in the artificial intelligence industry has intensified, with OpenAI, Google parent Alphabet and Meta Platforms introducing new models focused on coding, reasoning and AI agents to attract developers and enterprise customers.
