minimax-h3-ref2va-unpruned-q4
MiniMax-H3 served by vllm.cpp, LocalAI's own C++ port of vLLM. It generates
video AND audio jointly, so a clip comes back as an MP4 with a soundtrack.
Ask for speech in the prompt and the model lip-syncs it.
Runtime: vllm.cpp (backend vllm-cpp). Partition: ref2va. DiT layout:
unpruned. Format: Q4_K_M.
This entry is the Ref2VA partition, which takes REFERENCE conditioning (reference images, clips and audio) so the subject or voice carries into the clip. It refuses plain text-to-video and first/last-frame requests: for those use the matching fl2va entry. The DiT is the original time-embedder DiT (~19.9 GB).
Render status: verified render (end to end on the vllm.cpp model page).
Do NOT use the NVFP4 Ref2VA weights: they render a multicolour patch grid.
Q3_K_M of the same DiT is verified BAD and is not offered.
The vllm.cpp page records its renders with the DiT expanded to bf16. This
entry does not expand it and keeps the quantised weights resident, so a
render in that mode is not covered by the page.
The weights are one DiT, the Qwen3-VL-32B encoder (~14.6 GB), the video VAE
(~10.4 GB), the audio VAE and the tokenizer, plus the two VAE configs that
carry the latent statistics. The default canvas is 1344x768 at 124 frames
and 24 fps, about 5.2 seconds. Generation is slow: roughly 176 s per denoise
step at that canvas on a 20-SM device. Muxing the finished frames needs
ffmpeg on the host.
