MiniMax M2.7 vs Sonar
MiniMax M2.7 leads Sonar on the Artificial Analysis Intelligence Index, 22.8 to 7.7, and Sonar costs 1.2x less per output token ($1.00 vs $1.20 per million). Updated October 21, 2026; 3 benchmarks have a result for both.
MiniMax M2.7 or Sonar: which to pick
Only MiniMax M2.7 has a coding score, 36.2 on the Vibe Coding Index; Sonar has none, so the two cannot be ranked on coding.
Pick Sonar for output tokens 1.2x cheaper ($1.00 vs $1.20 per million).
