Anthropic announced on November 9, 2026, that it would release updated versions of two of its most powerful artificial intelligence (AI) models as the San Francisco-based lab also 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 for complex tasks like coding, while costing 20 percent less, the company said.
