Qwen vs GLM: Coding reproducibility comparison
nomorebuttsplz · reddit · 2026-08-30
An unscientific comparison between Qwen 3.8 Flash Next and GLM 5.3 Flash on reproducing a reference image into a game/tech demo.
- GLM Flash: Better visual fidelity. Used Canvas 2D and iterated continuously to create a playable pixel art 'walking simulator', showing no sign of stopping improvements.
- Qwen: Wrote a software renderer from scratch. Generated an animated city in 10 mins but struggled to follow the 'continue until no improvement' instruction, often stopping too early. In another run, it iterated for 80 mins but still didn't match the reference closely.
Verdict: GLM has a slight edge in instruction following (visual fidelity), while Qwen excels at speed.
