Pick GLM-5.2 if you want the stronger benchmark profile. Qwen3.5-27B only becomes the better choice if knowledge is the priority or you want the cheaper token bill.
GLM-5.2 is clearly ahead on the provisional aggregate, 94 to 61. 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 51.6. The single biggest benchmark swing on the page is Terminal-Bench 2.0, 81% to 41.6%. Qwen3.5-27B does hit back in knowledge, 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 Qwen3.5-27B. That is roughly Infinityx on output cost alone. GLM-5.2 gives you the larger context window at 1M, compared with 262K for Qwen3.5-27B.
GLM-5.2 is ahead on BenchLM's provisional leaderboard, 94 to 61. The biggest single separator in this matchup is Terminal-Bench 2.0, where the scores are 81% and 41.6%.
