Compressing AI Art Models 4.5x With PTQ4DiT Quantization Technique
Diffusion transformer models can be compressed 4.5x with new quantization technique PTQ4DiT while preserving image quality. This makes powerful AI-driven image generation accessible on resource-constrained devices like smartphones.
This is a Plain English Papers summary of a research paper called Compress AI Art Models 4.5x While Preserving Quality with New Quantization Technique. If you like these kinds of analysis, you should join AImodels.fyi or follow me on Twitter. Overview This paper proposes a post-training quantization method called PTQ4DiT for efficiently compressing diffusion transformer models. The key idea is to quantize the weights and activations of a pre-trained diffusion transformer model without significant loss in performance. The authors show that PTQ4DiT can achieve up to 4.5x compression ra...
