Anthropic: Claude Opus 4.6
Analysis Summary
Anthropic’s Claude Opus 4.6 is a text model that accepts images and files, with a 1M context window, tool use, and function calling. Its measured intelligence index is 38.8. The supplied data does not include coding or agentic benchmark results for this entry, so those capabilities should not be inferred from the product features alone.
The long context and file input make it a strong candidate for testing on lengthy documents, research synthesis, and client-facing writing where careful handling of source material matters. Tool integration can support workflow automation, but teams should evaluate execution reliability on their own tasks. Its listed input and output prices are 5 and 25, so the cost is better suited to high-value work than routine high-volume calls.
Use Opus 4.6 when quality and long-document capacity justify the premium. Pair it with a lower-cost model for simpler, repetitive tasks.
