What? Quantization converts AI model weights (the numbers that take up most of the model size) from relatively large and high-precision numbers (FP 32) to relatively small and low-precision numbers (FP16 or INT8) for performance (inference speed) improvements.

Why? AI models can be cumbersome to run within limited RT3D/game processor budgets, yet inference speed is still very important... it’s why you are running your model locally in the first place. Quantizing can increase the performance dramatically, and we’ll provide some benchmarks once this can be validated across our model test suite. The downside of quantization is quality loss. Calculating quality loss is tricky and subjective, so it’s best to test your results thoroughly to see if the degradation is acceptable. A good rule of thumb is that larger models degrade less with quantization.
