quantization
A compression technique that reduces high-precision values, such as 32-bit floating-point coordinates, to lower-precision representations, widely used in compressing 3D model geometry data to reduce file size.

When conformal prediction is used in combination with a quantized model, calibration must be performed on the quantized model, otherwise the theoretical guarantee of coverage becomes invalid.
Meshy's GLB file has an empty extensions list and can be opened without any decoder; SupaVoxel's compressed file declares two extensions, meshopt and quantization.
When choosing a quantization format, it is better to choose a slightly larger format that does not trigger CPU offloading (such as FP4) than to blindly pursue the smallest file size.
A smaller quantized model is not necessarily more VRAM-efficient or smoother to run—this is a counterintuitive trade-off.
