CogView3

CogView3: An Advanced Text-to-Image Generation Model by Tsinghua University

CogView3

CogView3 is the base version that adopts a cascaded framework and relay diffusion technology, significantly improving the quality and efficiency of text-to-image generation. Its main features include:

• Cascaded Framework: Generates images through a multi-stage process, gradually enhancing resolution from low to high.
• Relay Diffusion: Starts with a low-resolution image, progressively de-noising and de-blurring to finally generate high-quality images.
• Performance: In human evaluations, CogView3 outperformed SDXL by 77.0%, while its inference time is only half of SDXL.

CogView-3Plus

CogView-3Plus is an enhanced version of CogView3, based on the DiT (Diffusion Transformers) framework, further optimizing model performance. Its main features include:

• Zero-SNR Diffusion Noise Scheduling: Optimizes noise scheduling to improve the quality and efficiency of image generation.
• Joint Text-Image Attention Mechanism: Enhances the association between text and images, generating images that better match text descriptions.
• Multi-Resolution Support: Supports multiple image resolutions ranging from 512x512 to 2048x2048, increasing application flexibility.
