Mistral Large vs Sonar Pro
Sonar Pro leads Mistral Large on the Artificial Analysis Intelligence Index, 7.6 to 5.8, and Mistral Large costs 2.5x less per output token ($6.00 vs $15.00 per million). Updated October 21, 2026; 5 benchmarks have a result for both.
Mistral Large or Sonar Pro: which to pick
Neither model has a coding score yet, so the two cannot be ranked on coding.
Pick Mistral Large for output tokens 2.5x cheaper ($6.00 vs $15.00 per million) and work measured by LiveCodeBench (Artificial Analysis run) or AA Intelligence Index, where it leads.
