CogView3 is an open-source AI image generation model developed by Tsinghua University and Zhipu AI. It utilizes relay diffusion technology to generate high-resolution images in stages, starting with low-resolution images and enhancing them using relay super-resolution technology. This approach improves efficiency, reduces costs, and surpasses existing open-source models like SDXL in both quality and speed. CogView3 significantly reduces inference time while maintaining image detail, making it a powerful tool for various applications.
What is CogView3?
CogView3 is an open-source AI image generation model developed by Tsinghua University and Zhipu AI. It uses relay diffusion technology to create high-resolution images efficiently and cost-effectively.
Key Features of CogView3
Relay Diffusion Technology: Generates images in stages, starting with low-resolution images and enhancing them to high-resolution.
High Performance: Surpasses state-of-the-art models like SDXL in both quality and speed.
High Efficiency: Reduces inference time significantly, with a streamlined version being ten times faster than SDXL.
Multi-Resolution Support: Generates images in various resolutions from 512×512 to 2048×2048.
Technical Principles of CogView3
Cascading Framework: Uses a multi-stage generation process to gradually increase image resolution.
Relay Diffusion: Adds Gaussian noise to low-resolution images and starts the diffusion process from a relay point.
Zero-SNR Diffusion Noise Scheduling: Optimizes noise scheduling to improve image quality and speed.
Joint Text-Image Attention Mechanism: Enhances consistency between generated images and text descriptions.
Variational Autoencoder (VAE): Compresses high-dimensional pixel space into low-dimensional latent space.
Distillation Technology: Reduces the number of sampling steps required for model inference.
