 Sol-H3 produces five seconds of 1344x768 video with audio in just 1.653 seconds on Blackwell hardware.
Nvidia's Sol-H3 inference stack accelerates MiniMax-H3 video generation, producing five seconds of 1344x768 video with stereo audio in 1.653 seconds on an 8x B300 Blackwell system, beating real-time playback. It's fully open-sourced under Apache 2.0, supporting various hardware configurations.
Reactor partnered to release FastH3 via API, letting developers access the acceleration immediately without owning the GPUs themselves. Optimizations like dynamic sparse attention and fused kernels preserve quality while scaling toward interactive, 24 FPS video systems.
Key Capabilities:

• Faster Than Playback: Generates 5 seconds of video with audio in just 1.653 seconds.
• Fully Open Source: Released under Apache 2.0, supporting multiple hardware configurations.
• API Access: Available via Reactor's API, so developers don't need to own the GPUs.
