# MiniChat-1.5-3B - DeepSparse
This repo contains model files for [MiniChat-1.5-3B](https://huggingface.co/GeneZC/MiniChat-1.5-3B) optimized for [DeepSparse](https://github.com/neuralmagic/deepsparse), a CPU inference runtime for sparse models.

This model was quantized and pruned with [SparseGPT](https://arxiv.org/abs/2301.00774), using [SparseML](https://github.com/neuralmagic/sparseml).
## Inference
Install [DeepSparse LLM](https://github.com/neuralmagic/deepsparse) for fast inference on CPUs: 
```bash
pip install deepsparse-nightly[llm]
```
Run in a [Python pipeline](https://github.com/neuralmagic/deepsparse/blob/main/docs/llms/text-generation-pipeline.md):
```python
from deepsparse import TextGeneration

prompt = "How to make banana bread?"
formatted_prompt =  f"<s> [|User|]\n{prompt}</s>[|Assistant|]\n"

model = TextGeneration(model_path="hf:nm-testing/MiniChat-1.5-3B-pruned70-quant-ds")

print(model(formatted_prompt, max_new_tokens=200).generations[0].text)
"""
To make banana bread, you need to follow these steps:

1. Mix the ingredients:

```

## Prompt template
```

  <s> [|User|]\n
  {prompt}</s>
  </s>[|Assistant|]\n
```
## Sparsification
For details on how this model was sparsified, see the `recipe.yaml` in this repo and follow the instructions below.

```bash
git clone https://github.com/neuralmagic/sparseml
pip install -e "sparseml[transformers]"
python sparseml/src/sparseml/transformers/sparsification/obcq/obcq.py GeneZC/MiniChat-1.5-3B open_platypus --recipe recipe.yaml --save True
python sparseml/src/sparseml/transformers/sparsification/obcq/export.py --task text-generation --model_path obcq_deployment 
cp deployment/model.onnx deployment/model-orig.onnx
```
Run this kv-cache injection to speed up the model at inference by caching the Key and Value states:
```python
import os
import onnx
from sparseml.exporters.kv_cache_injector import KeyValueCacheInjector
input_file = "deployment/model-orig.onnx"
output_file = "deployment/model.onnx"
model = onnx.load(input_file, load_external_data=False)
model = KeyValueCacheInjector(model_path=os.path.dirname(input_file)).apply(model)
onnx.save(model, output_file)
print(f"Modified model saved to: {output_file}")
```
