please - do the same to TE
can you, please also convert the Text Encoder into this quant?
I don't think we should in this case, the current nvfp4_awq is a good quant and this would be worse.
I ran into attempts, but the models lacked currently necessary identifiable metadata that would cause inoperable errors (at least with an RDNA4 AMD GPU, comfyui 0.31.0 and after compiling https://github.com/0xDELUXA/comfy-kitchen_win-rocm). But the qwen3vl_32b_minimax_h3-w4a8_convrot over at https://huggingface.co/Winnougan/MiniMax-H3-INT4_Convrot_ComfyUI/ works.
Am definitely a fan of w4a8.
Btw, it seems you can use Qwen3 VL 4B as text encoder too, according to this https://www.reddit.com/r/StableDiffusion/s/0JOjvi7TbG
There's this one, and it works fine for me, but I didn't compare it to ComfyUI's NVFP4 checkpoint, so use it at your own discretion:
