Quantized INT4 ConvRot (W4A4) text encoder weights for MiniMax-H3-Image in ComfyUI. Built for the smallest single-file size with native comfy_kitchen support (no GGUF).Files:- qwen3vl_32b_minimax_h3_int4_convrot.safetensors (13.30 GB)Main 50-layer text encoder. 51% smaller than int8_convrot (27.14 GB) and smaller than nvfp4_awq (15.69 GB).- qwen3.5_9b_int4_convrot.safetensors (5.42 GB)Optional Qwen3.5-9B prompt enhancer for the Generate Text node.Setup:1. Drop the .safetensors file(s) into ComfyUI/models/text_encoders/2. Main encoder: load qwen3vl_32b_minimax_h3_int4_convrot.safetensors in CLIPLoader (type: minimax) and connect to MiniMaxH3ImageConditioning.3. Optional prompt enhancer: load qwen3.5_9b_int4_convrot.safetensors in CLIPLoader (type: minimax) and connect to Generate Text (TextGenerateV2).Links:- Hugging Face: <a target="_blank" rel="ugc" href="https://huggingface.co/Merserk/MiniMax-H3-Image-Text-Encoder-INT4-ConvRot">https://huggingface.co/Merserk/MiniMax-H3-Image-Text-Encoder-INT4-ConvRot</a>- Base model: <a target="_blank" rel="ugc" href="https://huggingface.co/MiniMaxAI/MiniMax-H3-Image">https://huggingface.co/MiniMaxAI/MiniMax-H3-Image</a>- ComfyUI weights &amp; workflows: <a target="_blank" rel="ugc" href="https://huggingface.co/Comfy-Org/MiniMax-H3-Image">https://huggingface.co/Comfy-Org/MiniMax-H3-Image</a>License:MiniMax H3 Image Community License Agreement: <a target="_blank" rel="ugc" href="https://huggingface.co/MiniMaxAI/MiniMax-H3-Image/blob/main/LICENSE">https://huggingface.co/MiniMaxAI/MiniMax-H3-Image/blob/main/LICENSE</a>
