Developer stefanionescu released comfyui-reactor-connector, a ComfyUI integration adding nodes for real-time video models (FastH3, Helios, LingBot, LongLive, Visko, SANA, X2) that run on Reactor's servers — no local weight downloads. Drop the node into your graph and connect to Save Video. FastH3 is fast and costs a fraction of a cent per second of output, and a companion node lets a scene continue across multiple clips in one run for chaining longer sequences without manual stitching.
