Price analysis
On a blended 3:1 input-to-output basis, Command A Reasoning costs about $23.18 per million tokens and DeepSeek-R1 Base costs about $10.35. DeepSeek-R1 Base is roughly 55% cheaper than Command A Reasoning. At high volume, that gap compounds quickly, so price should carry real weight unless the quality difference is decisive.
Both models list a 400,000-token context window. That is enough for long documents, large codebases and multi-step agent traces.
Verdict
Across 12 shared benchmarks, Command A Reasoning wins 6, DeepSeek-R1 Base wins 6, and 0 are tied. On the index average, Command A Reasoning leads DeepSeek-R1 Base by 0.1 points (80.2 versus 80.1).
The price picture favours DeepSeek-R1 Base. The context picture is effectively a tie. Those two dimensions often matter more than a few benchmark points once a model is good enough for the task.
If you need a single default, start with Command A Reasoning for quality-sensitive work and DeepSeek-R1 Base for high-volume, well-scoped tasks. Run both on a sample of your own traffic before locking in a choice.
Choose Command A Reasoning if
- You want the higher average benchmark score in this index.
- The workload needs multi-step reasoning.
Choose DeepSeek-R1 Base if
- Unit cost matters and you want the cheaper blended price.
- You need open weights for self-hosting or fine-tuning.
