What is VAR?
VAR represents a revolutionary breakthrough in visual generation, introducing a novel framework that enables GPT-style models to outperform diffusion models for the first time. The model implements a unique coarse-to-fine prediction approach, fundamentally reimagining how autoregressive learning works with images.
Implementation Details
Unlike traditional approaches that use raster-scan "next-token prediction," VAR introduces a "next-scale prediction" or "next-resolution prediction" methodology. This innovative approach allows the model to generate images in a hierarchical manner, demonstrating clear power-law Scaling Laws similar to large language models (LLMs).
