Anthropic launched Claude Opus 5 across all of its platforms, the company announced. The model is the new default for Claude Max and the strongest model on Claude Pro, and developers can access it through the Claude API.

Pricing remains at $5 per million input tokens and $25 per million output tokens, matching Opus 4.8, while fast mode runs at about 2.5 times the default speed for twice the base price. Anthropic says the model leads Frontier-Bench v0.1 and more than doubles Opus 4.8's result at a lower cost per task.

The company also reports that Opus 5 scored three times as high as the next-best model on ARC-AGI 3 and beat every other model at any given cost on OSWorld 2.0. Early-access customers reported strengths in difficult debugging, analytics, financial research, genomics, legal agent work, code review, and long-running coding tasks.

Anthropic says Opus 5 is its most aligned model so far and does not move the frontier in risky dual-use capabilities. Classifiers permit vulnerability discovery in source code but block binary scanning, penetration testing, and exploit generation, with flagged requests falling back to Opus 4.8 by default.
