Pick GLM-5 if you want the stronger benchmark profile. Gemini 2.5 Pro only becomes the better choice if coding is the priority or you need the larger 1M context window.
GLM-5 has the cleaner provisional overall profile here, landing at 67 versus 64. It is a real lead, but still close enough that category-level strengths matter more than the headline number.
GLM-5's sharpest advantage is in knowledge, where it averages 70.7 against 40.8. The single biggest benchmark swing on the page is HLE, 18.8% to 50.4%. Gemini 2.5 Pro does hit back in coding, so the answer changes if that is the part of the workload you care about most.
Gemini 2.5 Pro is also the more expensive model on tokens at $1.25 input / $10.00 output per 1M tokens, versus $1.00 input / $3.20 output per 1M tokens for GLM-5. That is roughly 3.1x on output cost alone. Gemini 2.5 Pro gives you the larger context window at 1M, compared with 200K for GLM-5.
GLM-5 is ahead on BenchLM's provisional leaderboard, 67 to 64. The biggest single separator in this matchup is HLE, where the scores are 18.8% and 50.4%.
GLM-5 has the edge for knowledge tasks in this comparison, averaging 70.7 versus 40.8. Inside this category, AA-Omniscience Hallucination Rate is the benchmark that creates the most daylight between them.
Gemini 2.5 Pro has the edge for coding in this comparison, averaging 63.8 versus 63.2. Inside this category, Terminal-Bench Hard is the benchmark that creates the most daylight between them.
