GLM-5.1 has the cleaner provisional overall profile here, landing at 84 versus 82. It is a real lead, but still close enough that category-level strengths matter more than the headline number.
GLM-5.1's sharpest advantage is in knowledge, where it averages 52.3 against 48. The single biggest benchmark swing on the page is Terminal-Bench 2.0, 63.5% to 68.4%. MiMo-V2.5-Pro does hit back in agentic, so the answer changes if that is the part of the workload you care about most.
GLM-5.1 is also the more expensive model on tokens at $1.40 input / $4.40 output per 1M tokens, versus $1.00 input / $3.00 output per 1M tokens for MiMo-V2.5-Pro. MiMo-V2.5-Pro gives you the larger context window at 1M, compared with 203K for GLM-5.1.
GLM-5.1 is ahead on BenchLM's provisional leaderboard, 84 to 82. The biggest single separator in this matchup is Terminal-Bench 2.0, where the scores are 63.5% and 68.4%.
