Anthropic releases Claude Opus 5 with nearly equivalent capability to Fable 5

Anthropic released Claude Opus 5, a new model that performs at the level of their controversial Fable 5 across many domains and is particularly strong on complex coding tasks. Fable 5 was taken offline earlier following concerns from the U.S. government, but is now being reintroduced with improved cybersecurity measures.
