Anthropic: Claude Opus 4.6
Analysis Summary
Claude Opus 4.6 is Anthropic's previous flagship, with an intelligence index of 46.5, a coding index of 47.6, and an agentic index of 66.6. It supports vision, tool use, and function calling across a 1,000,000 token context window, making it one of the most capable models for long-document analysis, complex coding, and multi-step autonomous tasks. Terminal benchmark and tau2 scores are both strong, confirming reliable agentic execution.
For businesses, Opus 4.6 is a strong fit for software engineering agents, contract and document analysis, and any workflow where answer quality and reasoning depth are critical. The 1M context window is a genuine advantage for large codebase or document tasks. Its successor, Claude Opus 4.7, now holds the flagship position, so teams starting new deployments should evaluate the newer version.
At $5.00 input and $25.00 output per million tokens, it is expensive and best reserved for high-value tasks. Existing deployments on Opus 4.6 remain well-served, but new projects should consider whether Opus 4.7 or Claude Sonnet 4.6 offers a better cost-to-capability trade-off.
