FreeVideo

FreeVideo is an open-source local inference engine that runs MiniMax H3 video models on consumer hardware.

FreeVideo is a local inference engine for MiniMax H3 on consumer GPUs, built on OpenVDN's 8-step VDN-H3 model with Video DeltaNet's hybrid attention. It coordinates VRAM, system memory, and disk to adapt weight placement and attention kernels to available hardware. The software runs as a ComfyUI plugin with launchers for Windows, macOS, and Linux, and supports text prompts, reference frames, images, videos, and audio. It features hardware-adaptive execution, low-memory inference, community LoRAs, and AI agent integration. Users can generate previews, edit videos on a timeline, and export results.
