Pick GLM-5 if you want the stronger benchmark profile. Composer 2.5 only becomes the better choice if agentic is the priority or you want the cheaper token bill.
GLM-5 has the cleaner provisional overall profile here, landing at 66 versus 64. It is a real lead, but still close enough that category-level strengths matter more than the headline number.
GLM-5 is also the more expensive model on tokens at $1.00 input / $3.20 output per 1M tokens, versus $0.50 input / $2.50 output per 1M tokens for Composer 2.5. Composer 2.5 is the reasoning model in the pair, while GLM-5 is not. That usually helps on harder chain-of-thought-heavy tests, but it can also mean more latency and more token spend in real use.
GLM-5 is ahead on BenchLM's provisional leaderboard, 66 to 64. The biggest single separator in this matchup is Terminal-Bench 2.0, where the scores are 69.3% and 56.2%.
Composer 2.5 has the edge for agentic tasks in this comparison, averaging 69.3 versus 56.2. Inside this category, Terminal-Bench 2.0 is the benchmark that creates the most daylight between them.
