ViTok-v2 scales to 5B parameters, advancing image autoencoder reconstruction and generation

Researchers have introduced ViTok-v2, a 5-billion parameter image autoencoder that scales to larger resolutions and parameter counts than previous models. This new model utilizes native resolution support and a DINOv3 perceptual loss to achieve better reconstruction quality across various image sizes. ViTok-v2 was trained on approximately 2 billion images and demonstrates improved performance at higher resolutions compared to existing methods. AI
