# Jan-nano GPTQ 4bit (vLLM-ready)
|
||||
|
||||
This is a 4-bit GPTQ quantized version of [Menlo/Jan-nano](https://huggingface.co/Menlo/Jan-nano), optimized for fast inference with [vLLM](https://github.com/vllm-project/vllm).
|
||||
|
||||
- **Quantization**: GPTQ (4-bit)
|
||||
- **Group size**: 128
|
||||
- **Dtype**: float16
|
||||
- **Backend**: `gptqmodel`
|
||||
- **Max context length**: 4096 tokens
|
||||
|
||||
---
|
||||
|
||||
## 🔧 Usage with vLLM
|
||||
|
||||
```bash
|
||||
vllm serve ./jan-nano-4b-gptqmodel-4bit \
|
||||
--quantization gptq \
|
||||
--dtype half \
|
||||
--max-model-len 4096
|
||||
```
