**Qwen3.6 27B**, self-quantized to GGUF by [Atomic Chat](https://atomic.chat). Built straight from Qwen's original weights with a per-tensor importance matrix, so this is not a repack of somebody else's files. Runs fully offline.
## Highlights
- **27.8B parameters**: the weights this repo quantizes.
- **Context length**: 262,144 tokens (256K), as published by Qwen.
- **64 layers**: Dense decoder.
- **Modalities**: Text, Image.
- **Full imatrix ladder**: every quant is calibrated with an importance matrix.
- **Agentic Coding:**: the model now handles frontend workflows and repository-level reasoning with greater fluency and precision.
- **Thinking Preservation:**: we've introduced a new option to retain reasoning context from historical messages, streamlining iterative development and reducing overhead.
> [!NOTE]
> These GGUFs are **self-quantized from the original weights**, not a repack. The importance matrix keeps low-bit quants closer to the full-precision model.
> [!IMPORTANT]
> Always pass `--jinja` so the **Qwen3.6 27B chat template** is applied. Without it the model can emit malformed turns.
## Model Overview
| Property | Value |
|---|---|
| Base model | `Qwen/Qwen3.6-27B` |
| Parameters | 27.8B |
| Layers | 64 |
| Context length | 262,144 tokens (256K) |
| Vocabulary | 248,320 |
| Modalities | Text, Image |
| Architecture | Dense decoder, 24 attention heads over 4 KV heads, `Qwen3_5ForConditionalGeneration` |
| This repo | GGUF quants (imatrix) and a vision mmproj |
> [!NOTE]
> Qwen3.6 27B is multimodal. This repo ships the **`mmproj-BF16.gguf`** vision projector. With `-hf` it is pulled automatically; otherwise pass `--mmproj`. Use `llama-mtmd-cli` or `llama-server` to feed images.
## Get started
Run Qwen3.6 27B locally with:
- **[Atomic Chat](https://atomic.chat):** the easiest path. Open the app, search `AtomicChat/Qwen3.6-27B-UDT-MTP-GGUF`, pick a quant, hit **Use this model**.
- **llama.cpp:** `llama-server -hf AtomicChat/Qwen3.6-27B-UDT-MTP-GGUF:None --jinja -c 8192`
- **Ollama:** `ollama run hf.co/AtomicChat/Qwen3.6-27B-UDT-MTP-GGUF:None`
- **LM Studio / Jan:** search the repo id, download any quant.
## Best practices
| Parameter | Value |
|---|---|
| temperature | 1.0 |
| top_p | 0.95 |
| top_k | 20 |
| min_p | 0.0 |
| repetition_penalty | 1.0 |
Qwen's recommended sampling configuration for `Qwen/Qwen3.6-27B`. Pass images through `llama-mtmd-cli` or `llama-server` with the projector.
## Run in llama.cpp
```bash
git clone https://github.com/ggml-org/llama.cpp
cmake llama.cpp -B llama.cpp/build -DBUILD_SHARED_LIBS=OFF -DGGML_CUDA=ON
cmake --build llama.cpp/build --config Release -j --target llama-cli llama-server
```
```bash
./llama.cpp/build/bin/llama-server \
-hf AtomicChat/Qwen3.6-27B-UDT-MTP-GGUF:None \
--jinja -ngl 99 -c 8192 -fa on
```
## How these were made
1. Download `Qwen/Qwen3.6-27B` (original weights).
2. Convert to f16 GGUF with [llama.cpp](https://github.com/ggml-org/llama.cpp).
3. Build an importance matrix over our calibration corpus.
4. Quantize the ladder with `--imatrix`.
