Qwen4 GGUF: where to download it, and which file to pick
There is no official Qwen4 GGUF yet, because Qwen4 weights have not been released. When Qwen4-27B ships, GGUF builds for llama.cpp, Ollama and LM Studio usually follow within a day. Here is where to look and how to choose.
Where Qwen4 GGUF files will appear
- Qwen on Hugging Face. Check first. Qwen sometimes publishes its own GGUF builds; the base model must be a Qwen/ repository.
- Unsloth. Published Qwen3.8-27B GGUF (unsloth/Qwen3.8-27B-GGUF), the most downloaded build of that model.
- LM Studio community. Published lmstudio-community/Qwen3.8-27B-GGUF, tuned for LM Studio.
- Ollama library. Lists Qwen3.8 as qwen3.8:27b (about 18 GB). Expect a qwen4 entry after release.

Which quantization to pick
| Format | Weights | Total, 8K context | Total, 32K | Total, 128K |
|---|---|---|---|---|
| BF16 | 54 GB | 56 GB | 57 GB | 64 GB |
| Q8_0 | 29 GB | 30 GB | 32 GB | 38 GB |
| Q6_K | 22 GB | 24 GB | 25 GB | 32 GB |
| Q5_K_M | 19 GB | 21 GB | 22 GB | 29 GB |
| Q4_K_M | 17 GB | 18 GB | 20 GB | 26 GB |
| IQ4_XS | 14 GB | 16 GB | 18 GB | 24 GB |
| Q3_K_M | 13 GB | 15 GB | 16 GB | 23 GB |
Estimates for a 27B model with the Qwen3.8-27B layout, including KV cache and about 1 GB of runtime overhead. Q4_K_M is the usual balance of size and quality; go to Q5_K_M or Q6_K if memory allows.
Calculate for your own GPU and context
How to avoid fake or broken files
- No official weights means no genuine Qwen4 GGUF. Anything older than the release is a rename or a fine-tune of another model.
- Check the model card’s base model. It should point to the official Qwen/ repository.
- Skip “uncensored”, “abliterated” or merged builds if you want the original model.
- If Qwen4 uses the new Qwen3.8-Flash-Next architecture, older llama.cpp builds may refuse to load it. Update llama.cpp, Ollama or LM Studio first.

Which Qwen4 GGUF should I download?
Q4_K_M for most 24 GB GPUs, Q5_K_M or Q6_K if you have 32 GB, Q8_0 for 48 GB. Use the VRAM calculator to check your context length.
Will Qwen4 GGUF work in Ollama and LM Studio?
Once their llama.cpp version supports the Qwen4 architecture. Update the app before you download.
