GLM-4.7-Flash vs Aion-2.0

Side-by-side benchmark comparison across agentic, coding, multimodal, knowledge, reasoning, and math workflows.

GLM-4.7-Flash is clearly ahead on the aggregate, 62 to 58. The gap is large enough that you do not need to squint at the spreadsheet to see the difference.

GLM-4.7-Flash's sharpest advantage is in coding, where it averages 45.9 against 33.2. The single biggest benchmark swing on the page is Terminal-Bench 2.0, 64 to 48. Aion-2.0 does hit back in instruction following, so the answer changes if that is the part of the workload you care about most.

GLM-4.7-Flash is the reasoning model in the pair, while Aion-2.0 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-4.7-Flash gives you the larger context window at 200K, compared with 128K for Aion-2.0.

Quick Verdict

Pick GLM-4.7-Flash if you want the stronger benchmark profile. Aion-2.0 only becomes the better choice if instruction following is the priority or you would rather avoid the extra latency and token burn of a reasoning model.
