Questions

Is MiniMax M2.1 better than MiniMax M2.5 for coding?

Only MiniMax M2.5 has a coding score, 37.2 on the Vibe Coding Index; MiniMax M2.1 has none, so the two cannot be ranked on coding. Pick MiniMax M2.1 for a lower cost per solved task ($0.59 against $0.62) and work measured by LiveCodeBench (Vals AI) or SWE-bench Verified (Vals AI), where it leads.

Which is cheaper, MiniMax M2.1 or MiniMax M2.5?

MiniMax M2.1 costs $0.30 per million input tokens and $1.20 per million output tokens; MiniMax M2.5 costs $0.30 and $1.20. Per solved SWE-bench Verified task, MiniMax M2.1 costs $0.59 and MiniMax M2.5 $0.62.

Which has the bigger context window, MiniMax M2.1 or MiniMax M2.5?

Neither: both take 205K tokens.

How many benchmarks is the MiniMax M2.1 vs MiniMax M2.5 comparison based on?

26 benchmarks have a result for both models as of October 22, 2026. MiniMax M2.1's coding index rests on 1 independent benchmark and MiniMax M2.5's on 3. Where only one model has a result, the page says so instead of naming a winner.
