Pick GLM-5.2 if you want the stronger benchmark profile. GLM-4.7 only becomes the better choice if coding is the priority or you want the cheaper token bill.
GLM-5.2 is clearly ahead on the provisional aggregate, 94 to 68. The gap is large enough that you do not need to squint at the spreadsheet to see the difference.
GLM-5.2's sharpest advantage is in agentic, where it averages 81 against 45.3. The single biggest benchmark swing on the page is Terminal-Bench 2.0, 41% to 81%. GLM-4.7 does hit back in coding, so the answer changes if that is the part of the workload you care about most.
GLM-5.2 is also the more expensive model on tokens at $1.40 input / $4.40 output per 1M tokens, versus $0.00 input / $0.00 output per 1M tokens for GLM-4.7. That is roughly Infinityx on output cost alone. GLM-5.2 gives you the larger context window at 1M, compared with 200K for GLM-4.7.
GLM-5.2 is ahead on BenchLM's provisional leaderboard, 94 to 68. The biggest single separator in this matchup is Terminal-Bench 2.0, where the scores are 41% and 81%.
GLM-5.2 has the edge for knowledge tasks in this comparison, averaging 67.2 versus 60.6. Inside this category, HLE is the benchmark that creates the most daylight between them.
GLM-4.7 has the edge for coding in this comparison, averaging 70.6 versus 62.1. GLM-5.2 stays close enough that the answer can still flip depending on your workload.
GLM-5.2 has the edge for agentic tasks in this comparison, averaging 81 versus 45.3. Inside this category, Terminal-Bench 2.0 is the benchmark that creates the most daylight between them.
