Anthropic, a US-based AI startup behind the Claude chatbot, unveiled Fable 5.2 and Mythos 5.2 ahead of a proposed IPO after it filed an S-1 with the US Securities and Exchange Commission on October 26.

The company said Fable 5.2, which became available on November 9, is built for complex coding, long-running projects, and coordinating more than 1,000 AI agents.

Mythos 5.2 has fewer safeguards for cybersecurity and life sciences work, and Anthropic is rolling it out to selected organizations through a verification program.

The announcement follows scrutiny of Anthropic’s AI safety.

In July, the company reported three incidents during its cybersecurity evaluations. In August, the UK AI Safety Institute published a report on unsanctioned AI agent behavior during cyber testing.

Anthropic said US officials and third-party evaluators reviewed the models before launch. It priced Fable 5.2 at US$8 per million input tokens and US$40 per million output tokens.
