I'm using Qwen3.5-9B as a prompt enhancer. Works with text generation with a reference image.

Walkthrough

Changes

Qwen3.5 GGUF integration

Layer / File(s) Summary
Qwen3.5 layout mapping and loading
loader.py, tests/test_targeted_quantization.py, README.md
The loader recognizes qwen35, maps llama.cpp tensor names, detects supported model sizes, and integrates Qwen3.5 text and mmproj loading. The README documents supported encoders and image-conditioning requirements.
Qwen3.5 tensor corrections
loader.py, tests/test_targeted_quantization.py
The loader reverses norm and A_log transformations, reorders tiled V heads, restores fused projection and convolution layouts, expands depthwise kernels, and handles quantized tensors.
Quantized output and fused vision tensors
loader.py, tests/test_targeted_quantization.py
Block-quantized lm_head.weight tensors are dequantized for direct matmuls, while BF16 tensors remain quantized. Fused vision tensors are detected and mapped through the Qwen3 vision layout.

Estimated code review effort: 4 (Complex) | ~45 minutes

Merge Risk: 🔵 Low · up to f7760

The PR adds Qwen3.5 model support, but quantized convolution weights may be reshaped incorrectly for some models, and several new tests need small correctness or lint fixes. It is mergeable with explicit owner awareness, though the quantized-weight handling should be addressed or accepted before relying on the new support broadly.

hey @blazewicz let me know if you are ready for me to review and merge

Text encoder + vision tower support. Image-to-text requires a
matching mmproj file.

1227-1227: 📐 Maintainability & Code Quality | 🔵 Trivial | ⚡ Quick win

The out_proj column-reorder assertion is vacuous.

head_marked(3, value_dim) repeats the same value across every column. Column permutation therefore cannot change the tensor. The assertion at Line 1254 passes even if _qwen35_v_reorder ignores axis=1.

Mark the columns with their V-head index so the permutation is observable.

Dequantize quantized Qwen3.5 conv1d.weight before reshaping. _qwen35_v_reorder leaves balanced-head tensors unchanged, so GGMLTensor.ndim can reflect raw storage while tensor_shape remains logical. Dequantize before the value.ndim check. If Qwen3.5 conversion support is added, protect this non-Linear tensor with keys_noquant or keys_hiprec; tools/convert.py currently has no Qwen3.5 rule.

Hugging Face unsloth/Qwen3.5-4B-GGUF repository model variants Qwen3.5 GGUF

💡 Result:

The unsloth/Qwen3.5-4B-GGUF repository on Hugging Face provides GGUF-formatted quantization variants of the Qwen3.5-4B model [1][2]. This repository is part of a series of quantized models provided by Unsloth, utilizing efficient quantization techniques to make the Qwen3.5 model architecture—a causal language model with a vision encoder [1]—more accessible for various hardware configurations. Model Variants The repository includes a variety of quantization levels to suit different memory and performance requirements. Examples of these GGUF files include, but are not limited to: - Standard quantizations such as Q4_K_M, Q5_K_M, and Q8_0 [2]. - Specialized variants like IQ4_NL, IQ2_M, and UD-Q4_K_XL [2][3]. - Associated files such as mmproj (multimodal projector) weights (e.g., mmproj-BF16.gguf) [2]. Background and Context - Model Architecture: Qwen3.5-4B is a post-trained causal language model featuring a vision encoder, 32 layers, and support for a native context length of 262,144 tokens [1]. - Release Information: The Qwen3.5 series was announced by Alibaba in February 2026, with the 4B, 2B, 0.8B, and 9B variants becoming available on the Hugging Face Hub by early March 2026 [4][5]. - Compatibility: The GGUF artifacts are designed for use with popular inference frameworks that support the GGUF format, such as llama.cpp, which are frequently used for running quantized models locally [6][7][1]. Users should check the Files and versions tab of the repository directly to see the full list of currently available quantization files, as the specific list of variants may be updated over time [2].

ComfyUI TEModel QWEN35 introduced commit Qwen3.5 text encoder support

💡 Result:

Support for Qwen3.5 text encoder models was introduced in ComfyUI through pull request #12771, which was merged via commit 404d7b9 on March 26, 2026 [1][2]. This implementation added a new dedicated module, comfy/text_encoders/qwen35.py, along with associated tokenizer configuration files and support for multiple Qwen3.5 model variants [2][3][4]. The update included several technical additions: - New TEModel enum variants for Qwen3.5 (e.g., TEModel.QWEN35_2B, TEModel.QWEN35_4B, TEModel.QWEN35_9B, and TEModel.QWEN35_27B) to identify and route these weights during model loading [1][4]. - Updates to comfy/sd.py to enable detection and loading of Qwen3.5 state dicts [1][2]. - Native support for multimodal tasks (such as image captioning and reverse prompt engineering) by integrating with ComfyUI's existing TextGenerate node logic [5][6]. - A mechanism for handling vision components within the Qwen3.5 architecture, allowing the model to process both text and image inputs [3][5]. Following the initial release, subsequent refinements have been made, including fixes for image handling in multi-image scenarios [7] and extensions to support additional model sizes like 31B [8]. Qwen3.5 models are typically used in ComfyUI by placing the .safetensors files in the models/text_encoders/ directory and loading them via standard nodes like CLIPLoader or specialized text generation nodes [5][6].

🎯 Functional Correctness | 🟡 Minor | ⚡ Quick win

torch.equal compares dtype as well as values. Both assertions compare a float32 corrected conv kernel against an expected tensor built from torch.arange(...), which defaults to int64. torch.equal returns False on a dtype mismatch, so these assertions can fail independently of the loader logic.

Thanks, @molbal . An honest disclaimer: I only have a mild idea what I'm doing here as I've never worked with comfy, torch of llama before, I had to use deepseek-v4-flash and Gemini 3.7-Flash to code it.

I wanted to use a bigger model than Qwen3-VL-8B for an image-to-prompt workflow and I noticed that ComfyUI has support for Qwen3.5 but your ComfyUI-GGUF was missing it. I found city96#438, but it didn't have any patches for the vision tower so it was limited to text encoding only.

I'll be happy to address any comments, but mind that the maths involved are currently black magic to me.

That's all right, thanks for the contribution. I've added the https://github.com/molbal/ComfyUI-GGUF/blob/main/.github/skills/add-model-architecture/SKILL.md skill for agents a few weeks ago, and it looks like your agent followed it.
