Base model: z-lab/Qwen3-Coder-Next-DFlash

Qwen3 Coder Next Dflash, self-quantized to GGUF by Atomic Chat. Built straight from Z Lab's original weights with a per-tensor importance matrix, so this is not a repack of somebody else's files. Runs fully offline.

Highlights

0.5B parameters: the weights this repo quantizes.
Context length: 262,144 tokens (256K), as published by Z Lab.
8 layers: Dense decoder.
Full imatrix ladder: every quant is calibrated with an importance matrix.

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.

Always pass --jinja so the Qwen3 Coder Next Dflash chat template is applied. Without it the model can emit malformed turns.

Model Overview

Property	Value
Base model	`z-lab/Qwen3-Coder-Next-DFlash`
Parameters	0.5B
Layers	8
Context length	262,144 tokens (256K)
Vocabulary	151,936
Modalities	Text
Architecture	Dense decoder, 32 attention heads over 4 KV heads, `DFlashDraftModel`
This repo	GGUF quants (imatrix). Quants: `Q8_0`

Choosing a quant

Quant	Size	Notes
`Q8_0`	0.5 GB	Effectively lossless, reference quality.

Pick the largest file that fits your (V)RAM with room for context. Q8_0 is the sweet spot for most setups; Q6_K or Q8_0 for maximum fidelity.

Get started

Run Qwen3 Coder Next Dflash locally with:

Atomic Chat: the easiest path. Open the app, search AtomicChat/Qwen3-Coder-Next-DFlash-GGUF, pick a quant, hit Use this model.
llama.cpp: llama-server -hf AtomicChat/Qwen3-Coder-Next-DFlash-GGUF:Q8_0 --jinja -c 8192
Ollama: ollama run hf.co/AtomicChat/Qwen3-Coder-Next-DFlash-GGUF:Q8_0
LM Studio / Jan: search the repo id, download any quant.
