MiniMax H3 Turbo Merge GGUF (8-step LoRA baked-in)

The MiniMax H3 FL2VA (pruned) DiT with the LightX2V Turbo 8-step v1.0 LoRA baked in.

and

The MiniMax H3 REF2VA (pruned) DiT with the LightX2V Turbo 4-step v1.0 LoRA baked in.

Modes: img2video, txt2video, FL2VA / T2VA / I2VA / REF2VA.

Samples (4B vs 8B Text Encoder)

Both samples use the same turbo Q4_K_M turbo GGUF diffusion model, prompt, and settings, only the text encoder changes (4B vs 8B).

4B Text Encoder + ClipProj (8-steps)

Notes

—Known Limitations Here
—ComfyUI + 4B/8B: matching mmh3-*-ClipProj-celeb-mlp is REQUIRED for small TEs.
—Audio is first-class on H3 — sample mp4s include stereo AAC.
—Frame grid: num_frames % 17 == 5 (90 and 124 are valid).
—MiniMax H3 — custom / other terms; read upstream before commercial use.
—LightX2V turbo LoRA — see lightx2v/Minimax-h3-Turbo and ModelTC/Minimax-H3-Turbo.
—Qwen3-VL — Apache-2.0 (Alibaba).
—ClipProj — MIT code (nicolab28/ComfyUI-ClipProj); matrices per NicoLab’s card.
