# MistralLite-AWQ Model

MistralLite-AWQ is a version of the [MistralLite](https://huggingface.co./amazon/MistralLite) model that was
quantized using the AWQ method developed by [Lin et al. (2023)](https://arxiv.org/abs/2306.00978).
The MistralLite-AWQ models are approximately **70% smaller** than those of MistralLite whilst maintaining comparable performance.

Please refer to the [original MistralLite model card](https://huggingface.co./amazon/MistralLite) for details about the model
preparation and training processes.

## MistralLite-AWQ Variants

## Dependencies
- [`autoawq==0.2.5`](https://pypi.org/project/autoawq/0.2.5/) – [AutoAWQ](https://github.com/casper-hansen/AutoAWQ) was used to quantize the MistralLite model.
- [`vllm==0.4.2`](https://pypi.org/project/vllm/0.4.2/) – [vLLM](https://github.com/vllm-project/vllm) was used to host models for benchmarking.

## Usage

## Inference via vLLM HTTP Host

### Launch Host
```bash
python -m vllm.entrypoints.openai.api_server \
    --model amazon/MistralLite-AWQ \
    --quantization awq
```

### Query Host
```bash
curl -X POST http://localhost:8000/v1/completions \
    -H "Content-Type: application/json" \
    -d '{ "model": "amazon/MistralLite-AWQ",
          "prompt": "<|prompter|>What are the main challenges to support a long context for LLM?</s><|assistant|>",
          "temperature": 0,
          "echo": false
    }'
```

## Inference via [vLLM Offline Inference](https://docs.vllm.ai/en/latest/getting_started/examples/offline_inference.html)
```python
from vllm import LLM, SamplingParams

prompts = [
   "<|prompter|>What are the main challenges to support a long context for LLM?</s><|assistant|>",
]
sampling_params = SamplingParams(temperature=0, max_tokens=100)

llm = LLM(model="amazon/MistralLite-AWQ")

outputs = llm.generate(prompts, sampling_params)

# Print the outputs.
for output in outputs:
    prompt = output.prompt
    generated_text = output.outputs[0].text
    print(f"Prompt: {prompt!r}, Generated text: {generated_text!r}")

```
