Minimax-H3-pruned is an open-weight video model from PurpleBlazey, listed in the AxForge catalogue. AxForge can bring it up on EU-owned hardware for you on request — with the licence handled where one is required.
About
Made these for personal experimentation in KoboldCPP's sdui interface: https://github.com/LostRuins/koboldcpp/releases/latest Video/Image Model Minimax H3 was quanted with sd-cli.exe: https://github.com/leejet/stable-diffusion.cpp In theory, pruning is lossless for inference, and only negatively affects training. Text Encoder/Clip-1 File Qwen3VL-32b had layers 50 to 63 pruned to save on VRAM, which are unused for video encoding. All K and IQ quants use imatrix. All UD quants use modified tensor profiles based on: https://huggingface.co/unsloth/Qwen3-VL-32B-Instruct-GGUF Image/Video VAE and Audio VAE Cloned from here for convenience: https://huggingface.co/Comfy-Org/MiniMax-H3/tree/main/vae From my testing, the Qwen3VL text encoders work surprisingly well even at UD-IQ1M. The Minimax H3 quants took at least Q3K to become usable. Q2K is a meme quant, but maybe adding enough steps can salvage something decent? After Q4K, quality bumps become less noticable. I find Q5K is the quality sweetspot while allowing VRAM room for resolution & video length. Qwen3VL-32b-Heretic is an experimental quant of https://huggingface.co/llmfan46/Qwen3-VL-32B-Instruct-ultra-uncensored-heretic I can confirm it works with Minimax H3, but I'd recommend a non-heretic version actually intended for it first.

Using it via the API
Once AxForge deploys purpleblazey-minimax-h3-pruned for you, it answers on the OpenAI-compatible API — the same base URL and keys as every other model. (purpleblazey-minimax-h3-pruned below is illustrative; you get the exact model name on deployment.)
$ curl -sS https://api.axforge.ai/v1/videos/generations \
-H "Authorization: Bearer $AXFORGE_API_KEY" \
-H "Content-Type: application/json" \
-d '{"model":"purpleblazey-minimax-h3-pruned","prompt":"a drone shot over a forest"}'
