MineBench: 3D Spatial AI Benchmark Reveals Surprises

MineBench introduces a new 3D spatial reasoning benchmark for AI models using Minecraft environments, revealing unexpected performance gaps and challenging

Someone built a benchmark that actually tests AI models on real 3D Minecraft tasks, and the results are pretty wild.

Turns out QWEN 3.5 performed close to (sometimes better than) Claude Opus 4.6, GPT-5.2, and Gemini 3 Pro on certain builds. The benchmark measures how well models handle spatial reasoning and complex instructions in a Minecraft environment.

Check it out:

The creator posted comparisons showing Opus 4.6 vs 4.5 and Opus 4.6 vs GPT-5.2 Pro with actual performance differences. Way more useful than generic “reasoning scores” since it tests models on practical 3D tasks.

Good resource for anyone picking models for spatial/gaming applications or just curious how different AI handles structured environments beyond text.
