What is Claude Opus?
Claude Opus is Anthropic's high-capability Claude model family designed for complex reasoning-heavy work.
When is it a good fit?
Use it for tasks like contract analysis, long-context synthesis, architecture-level problem solving, and other workflows where output quality has a narrow error margin.
Practical note
For many teams, Opus is most effective when paired with Sonnet: Sonnet handles high-volume draft generation, while Opus is reserved for final verification and refinement.
