A PyTorch implementation of Fractal Generative Models (FractalGen), enabling pixel-by-pixel high-resolution image generation. It includes pre-trained models on ImageNet 64x64/256x256, a Colab demo, and DDP training/evaluation scripts.

Use cases

• generate high-resolution images pixel by pixel
• run pretrained fractal generative models in a colab notebook
• train an autoregressive image generation model on imagenet
• reproduce results from the fractal generative models paper
• experiment with novel generative model architectures in pytorch

When to choose

• you want to reproduce or extend the FractalGen paper
• you need pixel-by-pixel high-resolution image generation with pretrained checkpoints
• you want a simple PyTorch research codebase for generative models

When to avoid

• you need production-ready image generation APIs
• you lack GPU resources for large 400M+ parameter models
• you need text-to-image or diffusion-based generation
