# Model Card for lyraLLMs

## Introduction

We have released **lyraLLMs**, a highly optimized and easy-to-use inference engine for LLMs.

**lyraLLMs** is suitable for NVIDIA GPUs:
- Volta (V100)
- Turing (T4)
- Ampere (A100/A10)
- Ada Lovelace (RTX 4090, etc.)

**lyraLLMs** supports many popular HuggingFace models as follows:
- [BELLE](https://huggingface.co/TMElyralab/lyraBELLE)
- [ChatGLM](https://huggingface.co/TMElyralab/lyraChatGLM)
- LLaMA
- LLaMA 2
- XVERSE
- Baichuan 1 & 2

**lyraLLMs** is fast, memory-efficient & easy to use with:
- State-of-the-art throughtput (up to 7K tokens/s for LLaMA 13B)
- Efficient memory usage of attention with FlashAttention2
- Quantization: MEMOPT mode (W8A16, W4A16), KVCache Int8
- Easy-to-use Python API to serve LLMs
- Streaming outputs

## Speed

### Settings
* Evaluated at tokens/s (input + output)
* Test on A100 40G, CUDA 12.0
* Enable the use of MEMOPT mode and KVCache Int8

## Usage

### Environment (Docker recommended)

- For Cuda 11.X: we recommend ```nvcr.io/nvidia/pytorch:22.12-py3```
- For Cuda 12.0: we recommend ```nvcr.io/nvidia/pytorch:23.02-py3```

```bash
docker pull nvcr.io/nvidia/pytorch:23.02-py3
docker run --rm -it --gpus all -v ./:/lyraLLMs nvcr.io/nvidia/pytorch:23.02-py3

pip install -r requirements.txt
```

### Convert Models

We have released multiple optimized models converted from original HuggingFace ones:
- ChatGLM-6B
- XVERSE-13B-Chat
- LLaMA-Ziya-13B
- Baichuan-7B, Baichuan-13B-Base, Baichuan-13B-Chat, Baichuan2-7B-Base, Baichuan2-7B-Chat, Baichuan2-13B-Base and lyraBaichuan2-13B-Chat
- Yi-6B, Yi-34B

Feel free to contact us if you would like to convert a finetuned version of LLMs.

### Inference

Refer to [README.md](./lyrallms/README.md) for inference of converted models with **lyraLLMs**.

### Python Demo

```python
from lyra_llama import lyraLlama

model_path = 'XXX' # 包含转换后的模型参数，配置，tokenizer文件目录
data_type = 'fp16'
memopt_mode = 0 # 如需使用MEMOPT模式推理, memopt_mode=1

model = lyraLlama(model_path, data_type, memopt_mode)

prompts = '列出3个不同的机器学习算法，并说明它们的适用范围.'
prompts = [prompts,] * 64

output_texts = model.generate(prompts, output_length=150, do_sample=False, top_k=30, top_p=0.85, temperature=1.0, repetition_penalty=1.0)
print(output_texts)

```
