Just ran and scored 63 3d model generations (via code) across high and no reasoning. 3D Modeling benchmark quickly shows spatial, logic and code performance of the model so I think it's a very good indicator of the quality.

Here are the results compared to Gemini 3.5 Flash:

    Model + config          CodeErr/gen   Cost/gen   Median time   Quality
    gemini-3.5-flash, low      0.71        $0.18        68s       baseline
    GLM 5.2, reasoning high    0.61        $0.18       289s         -6.0%
    GLM 5.2, reasoning off     1.52        $0.10       126s        -13.6%

Although it is cheaper, it is significantly slower, and results are worse overall. Surprisingly - high reasoning produces less code errors than gemini 3.5 flash, but when I actually look at the models they are worse.

Edit: I recently ran evals with Kimi 2.7 and MiniMax-M3 and this is clearly open source SOTA model, by far.
