Anthropic launched Claude Opus 5 across all platforms
Claude Opus 5 is now the default for Max, the top Pro model, and available to developers through the API.
TestingCatalog says pricing stays at $5 per million input tokens and $25 per million output tokens, with a faster mode offered at double the base price. Anthropic positions Opus 5 as a daily coding and knowledge-work model near Fable 5 capability at half the cost. The company cites gains over Opus 4.8 on several benchmarks and says early users saw strength in debugging, research, code review, and long-running coding tasks. Safety-flagged requests can fall back to another model, and Anthropic says cyber controls now allow source-code vulnerability discovery while blocking exploit-oriented work. TestingCatalog's note
