Anthropic Makes Its Latest AI Models Available Everywhere at Once

Anthropic released two upgraded AI models, Claude Fable 5 and Mythos 5, on June 9, 2026, simultaneously across all four major platforms: AWS, Google Cloud, Microsoft, and its own service. In the past, new models rolled out slowly as companies waited to integrate them. This time, the coordinated release means businesses can start using the new AI right away, whichever platform they already use.
