Base model: Qwen/Qwen3.6-35B-A3B

Qwen3.6 35B A3B, self-quantized to GGUF by 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

  • 36.0B parameters: the weights this repo quantizes.
  • Context length: 262,144 tokens (256K), as published by Qwen.
  • 40 layers: Mixture-of-Experts.
  • Modalities: the base model handles Text, Image; this repo ships text-only quants, it carries no vision projector.
  • 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 35B A3B chat template is applied. Without it the model can emit malformed turns.

Model Overview

| Property | Value |

|---|---|

| Base model | Qwen/Qwen3.6-35B-A3B |

| Parameters | 36.0B |

| Layers | 40 |

| Experts | 256 routed (top-8) |

| Context length | 262,144 tokens (256K) |

| Vocabulary | 248,320 |

| Modalities | Text, Image in the base model; text only in this repo, it ships no vision projector |

| Architecture | Mixture-of-Experts, 256 experts (top-8), 16 attention heads over 2 KV heads, Qwen3_5MoeForConditionalGeneration |

| This repo | GGUF quants (imatrix). Quants: Q4_K_M, UD-Q4_K_XL, Q5_K_M, Q6_K, Q8_0 |

Scores are Qwen's published results for the base Qwen/Qwen3.6-35B-A3B, not our own measurements. Quantization preserves the large majority of this; Q4_K_M and up stay close to full precision.

Choosing a quant

| Quant | Size | Notes |

|---|---|---|

| Q4_K_M | 21.2 GB | Recommended default. Best balance of size, speed and quality. |

| UD-Q4_K_XL | 21.5 GB | Dynamic. Embeddings and output kept at Q8_0 for higher quality at a Q4 footprint. |

| Q5_K_M | 24.7 GB | Higher quality, low loss. |

| Q6_K | 28.5 GB | Near lossless, noticeably lighter than Q8_0. |

| Q8_0 | 36.9 GB | Effectively lossless, reference quality. |

[!TIP]
Pick the largest file that fits your (V)RAM with room for context. Q4_K_M or UD-Q4_K_XL is the sweet spot for most setups; Q6_K or Q8_0 for maximum fidelity.

Get started

Qwen's recommended sampling configuration for Qwen/Qwen3.6-35B-A3B.

Run in llama.cpp

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
./llama.cpp/build/bin/llama-server \
    -hf AtomicChat/Qwen3.6-35B-A3B-GGUF:Q4_K_M \
    --jinja -ngl 99 -c 8192 -fa on

How these were made

1. Download Qwen/Qwen3.6-35B-A3B (original weights).

2. Convert to f16 GGUF with llama.cpp.

3. Build an importance matrix over our calibration corpus.

4. Quantize the ladder with --imatrix.

5. UD-Q4_K_XL additionally pins the token-embedding and output tensors to Q8_0.
