Overview

SANA is a cutting-edge, efficiency-focused codebase for generating high-resolution images and videos. It provides complete training and inference pipelines for a suite of powerful diffusion models, including SANA, SANA-1.5, SANA-Sprint, SANA-Video, SANA-WM, and Sol-RL. Engineered for speed and scalability, SANA significantly outperforms existing models in both computational efficiency and generation quality, making high-fidelity synthesis accessible on a wider range of hardware, even down to laptop GPUs with < 8GB VRAM through 4-bit quantization.

Key Features

• High-Resolution Synthesis: Generate stunning images and videos up to 4K resolution with exceptional detail.
• Unprecedented Efficiency: Achieve up to 20x smaller model sizes and 100x faster inference compared to prior state-of-the-art models like Flux-12B.
• Rapid Generation: SANA-Sprint offers near real-time image generation (0.1s per 1024px image on H100).
• Video Generation: Explore advanced capabilities with SANA-Video and LongSANA for both short clips and minute-long sequences, including controllable world models (SANA-WM).
• Scalable Training & Inference: SANA-1.5 introduces techniques for compute scaling during both training and inference, leading to improved quality.
• Advanced Techniques: Leverages Linear Attention, DC-AE (32x compression), decoder-only text encoders, Block Causal Linear Attention, Flow-DPM-Solver, and sCM Distillation for optimal performance.
• Low Resource Deployment: Models are deployable on GPUs with as little as 8GB VRAM using 4-bit quantization.
• Comprehensive Ecosystem: Includes support for LoRA fine-tuning, ControlNet integration, and compatibility with popular platforms like ComfyUI and SGLang.
• Reinforcement Learning Integration: Sol-RL provides efficient RL training for diffusion models, achieving significantly faster convergence.
