The verdict
These two models don't yet share verified results on the benchmarks we track, so judge them on specs, pricing and intended use. Command A is about 2.3x cheaper per blended million tokens (3:1 input:output mix). Command A also takes 262K of context versus 200K for Claude Opus 4.5. And Command A is open-weights (CC-BY-NC 4.0), so it can be self-hosted — a structural advantage if data control or vendor independence matters.
