   FastH3-Omni brings synchronized audio-video generation to Reactor preview

   Reactor introduced FastH3-Omni in a post shared by MiniMax on X, describing it as an open-source version of MiniMax's realtime H3 post-trained by FastVideo with haoailab and nuvalab that generates video with synchronized audio from a single prompt. The model supports first- and last-frame conditioning and audio input, and is available as an exclusive preview on the Reactor API until Oct. 20, 2026. Reactor also calls it the "fastest and highest-quality" open-source realtime H3 version, but no independent benchmarks were supplied to support that claim.
