What each one is for
Claude Opus 5
by Anthropic
Anthropic's model for complex agentic coding and enterprise work. Prompt caching cuts repeated input to a tenth of the base rate, which for an agent resending the same context every turn matters more than the headline price.
Cohere Command A
by Cohere
Cohere's enterprise flagship, built around retrieval-augmented generation and multilingual work, and sold heavily as a private deployment inside customer infrastructure.
Common questions
- Is Claude Opus 5 or Cohere Command A cheaper in 2026?
- Cohere Command A, for every workload modelled here. On a blended 3:1 basis it costs $4.38 per million tokens against Claude Opus 5's $10.00.
- Which has the larger context window?
- Cohere Command A, at 256K tokens against 200K. A larger window only helps if you can afford to fill it — the cost of one full-context request is in the table above.
- Which is cheaper for output-heavy work like agents?
- Cohere Command A, at $10.00 per million output tokens against $25.00. Reasoning tokens bill as output, so for agentic loops this axis usually decides the invoice regardless of what the input rates look like.
- What is not included in these figures?
- Batch-processing discounts, fine-tuning, long-context surcharges above a provider's standard tier, and any enterprise agreement. These are published pay-as-you-go list prices, checked against each provider's own pricing page on the date shown.
- Is switching from Claude Opus 5 to Cohere Command A worth it?
- On price alone it is about 56% cheaper on a blended basis. Whether that survives contact with your workload depends on output quality and on retry rate — a cheaper model that needs two attempts is not cheaper. Model the specific volumes in the calculator before you migrate.
