Command A vs Sonar Pro
Command A leads Sonar Pro on the Artificial Analysis Intelligence Index, 13.1 to 7.6, and Command A costs 1.5x less per output token ($10.00 vs $15.00 per million). Updated October 21, 2026; 5 benchmarks have a result for both.
Command A or Sonar Pro: which to pick
Neither model has a coding score yet, so the two cannot be ranked on coding.
Pick Command A for output tokens 1.5x cheaper ($10.00 vs $15.00 per million) and a larger context window (256K against 200K tokens).

Benchmark by benchmark
First the score: boards each model leads, per category, where both have a result. Then every board, a category to a fold; bars are each result on a 0 to 100 scale, so compare the two in a row, not one row with another.

What each workload costs
Three fixed token mixes at each model's listed price, so per-token rates become a bill.
Chat turn
1K input + 500 output tokens
Command A costs less
Repository review
50K input + 3K output tokens
Command A costs less
Agent loop
200K input + 10K output tokens
Command A costs less
Listed OpenRouter rates, without cache or batch discounts. A workload that does not fit a model's context window would need splitting.

Questions
Is Command A better than Sonar Pro for coding?
Neither model has a coding score yet, so the two cannot be ranked on coding. Pick Command A for output tokens 1.5x cheaper ($10.00 vs $15.00 per million) and a larger context window (256K against 200K tokens).
Which is cheaper, Command A or Sonar Pro?
Command A costs $2.50 per million input tokens and $10.00 per million output tokens; Sonar Pro costs $3.00 and $15.00. Cost per solved task is known for Command A only.
Which has the bigger context window, Command A or Sonar Pro?
Command A, with 256K tokens against 200K.
How many benchmarks is the Command A vs Sonar Pro comparison based on?
5 benchmarks have a result for both models as of October 21, 2026. Command A's coding index rests on 1 independent benchmark and Sonar Pro's on 0. Where only one model has a result, the page says so instead of naming a winner.
