cocktailpeanut shared a "MiniMax H3 family tree" chart (research cutoff Nov 10, 2026), researched and generated by ChatGPT, mapping the open-source ecosystem that has grown since H3 (FL2VA + Ref2VA + VAE, open weights) dropped on Aug 3.
The chart categorizes branches by purpose: general/hosted (fal H3 Max, HeyGen Video 1, etc.), speed/compression (Pika H3 Flex, FastH3, DMAD 4/8-step distills and quantizations), control/world models (Fun ControlNet-Unioin, Code World Model, SolarWM), editing/refinement (H3 Turnaround, chroma-h3, various LoRAs), plus derivatives from NVIDIA, UC San Diego, Alibaba, Microsoft Research and EPFL — totaling 49 family groups and 63 descendant nodes.
