What is VAR_CoDe?
VAR_CoDe is an innovative approach to visual auto-regressive modeling that introduces Collaborative Decoding (CoDe), a method that significantly improves the efficiency of image generation. The model cleverly partitions multi-scale inference between a large and small model, leveraging reduced parameter demands at larger scales and unique generation patterns across different scales.
Implementation Details
The model achieves remarkable efficiency improvements through its collaborative architecture, demonstrating a 1.7x speedup and approximately 50% reduction in memory usage while maintaining image quality (FID increase from 1.95 to 1.98). When configured with decreased drafting steps, it can achieve up to 2.9x acceleration, generating over 41 images per second at 256x256 resolution on a single NVIDIA 4090 GPU while maintaining a FID of 2.27.
