MiniMax open-sources FastH3: 720p audio-video streaming at $0.007/second
Scobleizer · x · 2026-09-03
Reactor launched MiniMax's latest open-source model FastH3, which streams 720p video with synchronized audio at $0.007/second and supports first-frame image control.
A demo app showcases an infinitely continuing AI cooking show: FastH3 generates audio-video into a live WebRTC track while the app keeps a seamless clip queue, applying late prompts and image-based props without stalling playback. The example is open-sourced in the reactor-cookbook repo.
