ConvRot: Rotation-Based Plug-and-Play 4-bit Quantization for Diffusion Transformers

arXiv — cs.CVThursday, December 4, 2025 at 5:00:00 AM
  • The introduction of ConvRot, a rotation-based quantization method for diffusion transformers, aims to address the challenges of increasing memory usage and inference latency as model sizes grow. This method utilizes a regular Hadamard transform to effectively manage outliers and reduce computational complexity from quadratic to linear, facilitating 4-bit quantization without the need for retraining.
  • This development is significant as it enhances the practical deployment of diffusion transformers, allowing for efficient image generation while maintaining visual quality. The integration of ConvRot into existing frameworks could streamline processes in AI applications, making them more accessible and efficient.
  • The advancements in quantization and pruning techniques reflect a broader trend in AI towards optimizing model performance while minimizing resource consumption. As various methods emerge to tackle similar challenges in diffusion transformers, the focus on efficiency and scalability is becoming increasingly critical in the field of artificial intelligence, particularly in video and image generation.
