# DeciLM-7B - GPTQ
- Model creator: [Deci](https://huggingface.co./Deci)
- Original model: [DeciLM-7B](https://huggingface.co./Deci/DeciLM-7B)
## Description
This repo contains GPTQ model files for [Deci's DeciLM-7B](https://huggingface.co./Deci/DeciLM-7B).
### About GPTQ
GPTQ is a method that compresses the model size and accelerates inference by quantizing weights based on a calibration dataset, aiming to minimize mean squared error in a single post-quantization step. GPTQ achieves both memory efficiency and faster inference.
It is supported by:
- [Text Generation Webui](https://github.com/oobabooga/text-generation-webui) - using Loader: AutoAWQ
- [vLLM](https://github.com/vllm-project/vllm) - version 0.2.2 or later for support for all model types.
- [Hugging Face Text Generation Inference (TGI)](https://github.com/huggingface/text-generation-inference)
- [Transformers](https://huggingface.co./docs/transformers) version 4.35.0 and later, from any code or client that supports Transformers
- [AutoAWQ](https://github.com/casper-hansen/AutoAWQ) - for use from Python code
## Shared files, and GPTQ parameters
Models are released as sharded safetensors files.

## How to use
You will need the following software packages and python libraries:
```json
build:
cuda_version: "12.1.1"
system_packages:
- "libssl-dev"
python_packages:
- "torch==2.1.2"
- "vllm==0.2.6"
- "transformers==4.36.2"
- "accelerate==0.25.0"
```
Here is the code for app.py
```python
from vllm import LLM, SamplingParams
class InferlessPythonModel:
def initialize(self):
self.sampling_params = SamplingParams(temperature=0.7, top_p=0.95,max_tokens=256)
self.llm = LLM(model="Inferless/deciLM-7B-GPTQ", quantization="gptq", dtype="float16")
def infer(self, inputs):
prompts = inputs["prompt"]
result = self.llm.generate(prompts, self.sampling_params)
result_output = [[[output.outputs[0].text,output.outputs[0].token_ids] for output in result]
return {'generated_result': result_output[0]}
def finalize(self):
pass
```
