Anthropic Unveils New Fable, Mythos AI Models Ahead Of IPO

Anthropic PBC has introduced new versions of its powerful artificial intelligence models, Mythos and Fable. The move is aimed at strengthening the company's position as a leader in AI development just before its long-awaited stock market debut on Wall Street.

Anthropic said Fable 5.2, which is set to be released Monday, can handle harder software engineering tasks, do more work with hardware such as controlling robots, and manage projects that run for a long time. It is also designed to coordinate more than 1,000 AI agents at once. Mythos 5.2 is the same model but has fewer safety protections for cybersecurity and life sciences work. Anthropic is making it available to selected organizations through a verification program it announced earlier.

Anthropic said both models are faster than earlier versions, and Fable costs less to use.

The new releases could help Anthropic compete with rivals such as OpenAI in an increasingly crowded market. The company, which makes Claude, is getting closer to a major stock market listing that could happen as soon as this month.

However, the announcement could also bring more attention and questions about the company. People inside and outside the technology industry are warning that AI could create serious safety risks, including risks that could cause widespread harm.

The Democratic Party's strong results in the US midterm elections are also expected to increase support for stronger AI safety rules. They could also lead to new difficulties in building data centers, which are used to train and run AI models.
