GLM 5.1 vs MiniMax M2.1
GLM 5.1 leads MiniMax M2.1 on the Artificial Analysis Intelligence Index, 26.1 to 20.9, and MiniMax M2.1 costs 3.7x less per output token ($1.20 vs $4.40 per million). Updated October 22, 2026; 26 benchmarks have a result for both.
GLM 5.1 or MiniMax M2.1: which to pick
Only GLM 5.1 has a coding score, 49.2 on the Vibe Coding Index; MiniMax M2.1 has none, so the two cannot be ranked on coding.
Pick MiniMax M2.1 for output tokens 3.7x cheaper ($1.20 vs $4.40 per million) and a lower cost per solved task ($0.59 against $0.60).

Questions
Is GLM 5.1 better than MiniMax M2.1 for coding?
Only GLM 5.1 has a coding score, 49.2 on the Vibe Coding Index; MiniMax M2.1 has none, so the two cannot be ranked on coding. Pick MiniMax M2.1 for output tokens 3.7x cheaper ($1.20 vs $4.40 per million) and a lower cost per solved task ($0.59 against $0.60).
Which is cheaper, GLM 5.1 or MiniMax M2.1?
GLM 5.1 costs $1.40 per million input tokens and $4.40 per million output tokens; MiniMax M2.1 costs $0.30 and $1.20. Per solved SWE-bench Verified task, GLM 5.1 costs $0.60 and MiniMax M2.1 $0.59.
Which has the bigger context window, GLM 5.1 or MiniMax M2.1?
Neither: both take 205K tokens.
How many benchmarks is the GLM 5.1 vs MiniMax M2.1 comparison based on?
26 benchmarks have a result for both models as of October 22, 2026. GLM 5.1's coding index rests on 3 independent benchmarks and MiniMax M2.1's on 1. Where only one model has a result, the page says so instead of naming a winner.
