Anthropic: Claude Opus 4.8
Anthropic
Opus 4.8 is Anthropic's most capable generally available model in the Opus family, built for long-horizon agentic work and complex reasoning. It supports text, image, and file inputs with text output, maintains coherence across extended sessions, and improves on Opus 4.7 with stronger judgment, honesty about uncertainty, and better end-to-end collaboration on multi-step tasks.
