Anthropic launches Fable 5.2 and Mythos 5.2 ahead of IPO

Anthropic announced on Monday that it would release updated versions of two of its most powerful artificial intelligence (AI) models as the company prepares for a highly anticipated IPO this month. The new models, Fable 5.2 and Mythos 5.2, can perform up to 30 percent faster than previous versions, particularly on complex tasks such as coding, while costing 20 percent less, the company said.

Anthropic says revenue surged 1100% ahead of IPO storyline 1 Both are built on the same underlying model. Fable 5.2 has safeguards that block most cybersecurity and biology tasks, which lets Anthropic offer it to all users.

Mythos 5.2 has fewer of those restrictions and is available only to vetted organisations working in cybersecurity or biomedical research.
