News

• 🔥 [2026/10] 🎮 StreamRender-H3 is released! A code-driven streaming render runtime connecting a controllable Three.js game engine to a multi-GPU H3 streaming renderer with browser video feedback. See Project | Code.
• 🔥 [2026/10] ⚡ Sol-H3 brings MiniMax-H3 to a single RTX 5090 or DGX Spark, now also in ComfyUI: one 1344×768 clip with audio in 35.5 s on one RTX 5090 (989.0 s for the original 50-step model). See Project | Code.
• 🔥 [2026/09] 🔍 SoL-Refiner is released! One-step refinement turns low-resolution video drafts into high-resolution video, with code and models for LTX-2.3 and MiniMax-H3. See Project | Code.
• 🔥 [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.
