GLM-4.7-Flash vs GPT-4o mini

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

GLM-4.7-Flash is clearly ahead on the aggregate, 64 to 43. The gap is large enough that you do not need to squint at the spreadsheet to see the difference.

GLM-4.7-Flash is the reasoning model in the pair, while GPT-4o mini 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 GPT-4o mini.

Quick Verdict

Pick GLM-4.7-Flash if you want the stronger benchmark profile. GPT-4o mini only becomes the better choice if coding is the priority or you would rather avoid the extra latency and token burn of a reasoning model.
