Pairwise benchmark snapshot · Aug 16, 2026
This page compares Claude Opus 4.5 (Anthropic) and Command A (Cohere) using the latest snapshots we have as of Aug 16, 2026. On preference Elo, Claude Opus 4.5 is ahead by 224 points (1,568 vs 1,344; seed-bootstrap (Aug 1, 2026)). On SWE-bench coding, Claude Opus 4.5 resolves 76.8% versus 42.6% (seed-bootstrap (Aug 1, 2026)). Command A streams faster (118 tok/s) while Command A is the cheaper output token ($10/1M). Command A has the larger context window (256k tokens). Every cell below is a dated snapshot from a named public source — we do not invent missing scores, and we do not run SWE-bench ourselves.

The Feb refresh made 4.5 a coding reference. Newer Opus SKUs exist; this row stays as the dated harness point.
Mar 2025. RAG and tools, not a frontier Elo play. Listed so “command a benchmark” has a sourced page.
