This repository contains two ComfyUI safetensors files built fromllmfan46/Qwen3\-VL\-32B\-Instruct\-ultra\-uncensored\-heretic.
- a normal MiniMax-H3 text/vision conditioning encoder containing language layers 0–49; and
- an optional generation-only tail containing layers 50–63, the final norm, and LM head for prompt enhancement.
MiniMax-H3 consumes the unnormalized hidden state after language layer 49. This checkpoint therefore includes the Qwen3-VL embedding, language layers 0–49, and the complete vision tower. It intentionally omits language layers 50–63, the final language norm, and the LM head.

The full upstream BF16 source remains available in thesource repository. It is not duplicated here. A BF16 MiniMax-H3 package is over 51 GB and is not practical for a 32 GB RTX 5090; this INT8 build is the recommended version.

The tail is not a standalone CLIP and does not duplicate the token embedding or vision tower. It is loaded temporarily by theComfyUI\-MiniMax\-H3\-Guidenode and reuses the 0–49 layers in the connected standard MiniMax-H3 CLIP. After generation, it is unloaded and the original conditioning CLIP remains unchanged.

Place both safetensors files under:
ComfyUI/models/text_encoders/MiniMax-H3/
Select it inCLIPLoaderwith typeminimax(MiniMax-H3). Use a current ComfyUI checkout with its pinnedcomfy\-kitchendependency.
For prompt enhancement:
- Load the 0–49 conditioning checkpoint with ComfyUI’s standard
CLIPLoader, typeminimax. - Connect that CLIP toMiniMax H3 Prompt Enhancer (optional CLIP tail).
- Select the 50–63 tail in the node’s
clip\_taildropdown. - Send
enhanced\_promptand the returned, unchangedclipto the normal MiniMax-H3 guide node.
If the connected CLIP is already a complete generative model, leaveclip\_tailat\[none — connected CLIP is already complete\]. The enhancer then calls the connected CLIP’s ordinarygenerate\(\)path, without loading or requiring this tail.
These are ComfyUI checkpoints, not a complete Transformers generation repository.

The conditioning checkpoint and enhancer passed actual runtime tests:

CLIPLoaderloaded the conditioning model with exactly 50 language layers and no final norm or LM head. - The optional tail path generated a token through all 64 layers, returned the exact same CLIP object, then left it at exactly 50 layers with no norm/head.
- The returned CLIP successfully encoded MiniMax conditioning after the tail was unloaded: finite
\(1, 4, 5120\)output with token tags. - The no-tail path was tested with a complete Qwen3-VL-4B ComfyUI CLIP and generated successfully without loading the MiniMax tail.
The local CUDA 12.8 PyTorch build used fallback operations because thiscomfy\-kitchenrelease recommends CUDA 13.0+ for its optimized kernels. The encode nevertheless completed successfully. A current ComfyUI environment with its recommended PyTorch build is preferred.
https://huggingface.co/ethanfel/Qwen3-VL-32B-Ultra-Heretic-MiniMax-H3-ComfyUI-INT8-ConvRot#provenanceProvenance
Pinned upstream source:
repository: llmfan46/Qwen3-VL-32B-Instruct-ultra-uncensored-heretic
revision: c44b949b30d111666a5ed9851c5cd633ed39b070
Both upstream BF16 shards were downloaded at that revision and verified against their Hugging Face LFS SHA-256 values before packaging.
The source model card reports Heretic v1.2.0 ARA edits targetingattn\.o\_projin language layers 31–40. All of those edited layers are inside MiniMax-H3’s retained 0–49 range, so the uncensoring edits are present in this checkpoint. The source reports 4/100 refusals versus 99/100 for the original, KL divergence 0.0421, PIQA 92.87%, and MMLU 79.87%.
Abliteration reduces refusal behavior but does not guarantee that every refusal or safety behavior is removed, and it may affect model quality.
https://huggingface.co/ethanfel/Qwen3-VL-32B-Ultra-Heretic-MiniMax-H3-ComfyUI-INT8-ConvRot#conversionConversion
The MiniMax-H3 BF16 package was converted withsilveroxides/convert\_to\_quant1.3.1. The successful build used AdamW AdaRound optimization with plateau early stopping, not simple rounding:

-i qwen3vl_32b_minimax_h3_ultra_uncensored_heretic_bf16.safetensors \

The language block matrices use learned ConvRot. Only the token embedding uses simple tensorwise INT8 because ComfyUI embedding lookup requires that layout. The vision tower is retained exactly in BF16.
The generation tail was packaged from the same pinned source and converted separately:
env PYTHONPATH=.deps .deps/bin/ctq \
-i qwen3vl_32b_minimax_h3_generation_tail_50_63_bf16.safetensors \

--fullmatch
The 98 transformer matrices use learned AdamW ConvRot. The LM head uses simple row-wise ConvRot so the enhancer can compute its 151,936 output rows in small chunks and avoid a multi-gigabyte temporary dequantization peak.
https://huggingface.co/ethanfel/Qwen3-VL-32B-Ultra-Heretic-MiniMax-H3-ComfyUI-INT8-ConvRot#validationValidation
The completed file passed structural validation of every tensor, dtype, shape, scale, per-layer descriptor, and global quantization metadata entry. All 551 protected BF16 tensors were compared byte-for-byte against the packaged BF16 source and were unchanged.
The tail also passed exact structural validation: the retained 57 BF16 tensors (304,128 bytes) are byte-identical to the source; its 99 INT8 weights, scales, descriptors, and global quantization metadata all match the declared layout. Combining the base source topology (902 tensors) with the tail source topology (156 tensors) reconstructs all 1,058 tensors of the full model with no key collision.
