Frequently asked questions
Which is cheaper, Sonar Pro or Command A?
On price Command A edges it, $4.75 per million tokens blended versus $6.60, about 28 per cent less. A single 100K-input, 10K-output job costs $0.350 on Command A against $0.450 on Sonar Pro. Blended cost weights input at 70% and output at 30%; price your own token split for an exact answer, since the cheaper model on a blended basis is not always cheaper for your workload.
Which performs better, Sonar Pro or Command A?
Capability favours Sonar Pro, ahead on 3 of 4 suites they both publish. The widest gap is on GPQA Diamond, where Sonar Pro leads by 7 points. These are the figures each provider or public leaderboard publishes, not results we re-run, and a benchmark average can hide the specific behaviour your workload depends on.
Which has the larger context window, Sonar Pro or Command A?
Command A reads more in one request: 256,000 tokens of context against 200,000. The context window caps everything in a single request: prompt, retrieved documents, conversation history and the model’s own output all share it.
Can I compare Sonar Pro and Command A on my own numbers?
Yes. Open both in the side-by-side comparison tool to see every field at once, or use the token calculator to price your actual prompt and monthly request volume against each model. Both are free and need no sign-up.
