The text encoder also needs to be quantized. From Comfy’s repository, it appears to be a version fine‑tuned by Minimax.

UNET will probably work (untested)?
GGUF from realrebelai(https://huggingface.co/realrebelai/MiniMax-H3_GGUFs/tree/main) is in ComfyUI format, so it doesn't need mmproj.
General GGUF (like unsloth, etc.) will probably need mmproj (untested).

Anyway, maybe because using FL Unet or because of a prompt issue, the style has changed.
but, realrebelai's TE seems to be working.

@m8rr Perhaps the TE could try using int4_convrot — it should be more convenient than Q4_K_M.gguf, since it’s natively supported by Comfy Core.
