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
--jinjaso 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_MorUD-Q4_K_XLis the sweet spot for most setups;Q6_KorQ8_0for maximum fidelity.

How these were made
- Download
Qwen/Qwen3.6-35B-A3B(original weights). - Convert to f16 GGUF with llama.cpp.
- Build an importance matrix over our calibration corpus.
- Quantize the ladder with
--imatrix. UD-Q4_K_XLadditionally pins the token-embedding and output tensors toQ8_0.
