## News
- 🔥 [2026/09] ⚡ **SANA-Video 2.0 5B 4-Step Preview** is released! The DMD preview generates 720p videos in four denoising steps and supports 5-second and 8-second outputs. See Online Demo | 4-Step Weights | Doc | Project.
- 🔥 [2026/08] 🎬 **SANA-Video 2.0** training, inference, model architecture, and 5B 720p checkpoint are released! The 8-second model supports both text-to-video and text-image-to-video generation, with hybrid linear/softmax attention and Attention Residuals. See Online Demo | Project | Doc | Model Zoo | Weights.
- 🔥 [2026/08] ⚡ **Sol Engine: Day-One MiniMax-H3 Acceleration** is available! The 33B omni-modal audio+video DiT runs **3.95×** faster on GB200, reached in 4.5 hours of optimization, and up to **4.52×** on hardware that sits on a desk — 3.92× on DGX Spark, 4.52× on GeForce RTX 5090 — with no distillation, no LoRA, and no calibration pass. See GB200 Blog | On-Device Blog.
- 🔥 [2026/07] 🌍 **SANA-Streaming** training is released! Includes bidirectional and distillation training. See Doc.
- 🔥 [2026/07] 🌍 **SANA-WM** Stage-1 training is released! Includes bidirectional, chunk-causal, and distillation training. See Doc.
- 🔥 [2026/06] 🎬 **SANA-Streaming: 2B Model for Real-time Streaming Editing** is released! Supports 720p, 1-min video editing. A pioneer work for streaming editing. See Project | Doc | Paper | Reactor Demo.
- 🔥 [2026/05] 🌍 **SANA-WM: 2.6B Controllable World Model** is released! Supports 720p, 1-min video generation with 6-DoF camera control. A new baseline for World Modeling and Embodied AI. See Project | Doc | Paper | Reactor Demo.
- 🔥 [2026/04] ⚡ **Sol-RL: NVFP4 Rollout, BF16 Training RL** is available! All training recipes for **SANA**, **FLUX.1**, and **SD3.5-L**, together with bundled post-training datasets, are released. See Sol-RL doc | Page | Paper.
- 🔥 [2026/03] 📺 **SANA-Video 720p model with LTX-VAE** is released. Use it with LTX2 Refiner to upscale the videos to 2K resolution! See Model Zoo, SANA-Video doc and Blog about refiner.
- 🔥 [2026/03] 💪 **Post Training Infra: SANA × Cosmos-RL** — We partner with Cosmos-RL to provide a complete RL infrastructure for SANA. You can now post-train (SFT/RL) SANA-Image and SANA-Video with state-of-the-art algorithms (e.g. Diffu
