Qwen3 Coder 30B 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
- 30.5B parameters: the weights this repo quantizes.
- Context length: 262,144 tokens (256K), as published by Qwen.
- 48 layers: Mixture-of-Experts.
- Full imatrix ladder: every quant is calibrated with an importance matrix.
- Significant Performance: among open models on Agentic Coding, Agentic Browser-Use, and other foundational coding tasks.
- Agentic Coding: supporting for most platform such as Qwen Code, CLINE, featuring a specially designed function call format.
[!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 Coder 30B A3B chat template is applied. Without it the model can emit malformed turns.
Model Overview
Choosing a quant
[!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
Run Qwen3 Coder 30B A3B locally with:
- Atomic Chat: the easiest path. Open the app, search
AtomicChat/qwen3-coder-30b-a3b-GGUF, pick a quant, hit Use this model.
- llama.cpp:
llama-server -hf AtomicChat/qwen3-coder-30b-a3b-GGUF:Q4_K_M --jinja -c 8192
- Ollama:
ollama run hf.co/AtomicChat/qwen3-coder-30b-a3b-GGUF:Q4_K_M
- LM Studio / Jan: search the repo id, download any quant.

How these were made
- Download
Qwen/Qwen3-Coder-30B-A3B-Instruct (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_XL additionally pins the token-embedding and output tensors to Q8_0.
