## Special Notes

We have released **7 Baichuan models of lyra version** including Baichuan-7B, Baichuan-13B-Base, Baichuan-13B-Chat, Baichuan2-7B-Base, Baichuan2-7B-Chat, Baichuan2-13B-Base and Baichuan2-13B-Chat. 

These highly optimized Baichuan models are suitable for Ampere (A100/A10) as well as Volta (V100).

## Model Card for lyraBaichuan

lyraBaichuan is currently the **fastest Baichuan models** (Baichuan-7B, Baichuan-13B, Baichuan2-7B, Baichuan2-13B) available. The inference speed of lyraBaichuan has achieved up to **4300+ tokens/s** on A100, up to **2.4x** acceleration upon the torch version.

Among its main features are:
- device: Nvidia GPU with Amperer architecture or Volta architecture (A100 or higher, V100).
- batch_size: compiled with dynamic batch size, maximum depends on device. 
- MEMOPT mode: significantly optimized VRAM usage and increased speed

We use the Baichuan2-7B-Base and Baichuan2-13B-Base model for measurement, but this optimized inference is also applicable to other Baichuan models, including Baichuan-7B and Baichuan-13B.

## Speed

* Evaluated at tokens/s (#tokens of input and output divided by inference time cost)
* test on A100 40G
* MEMOPT mode

## Docker Environment Recommendation

- 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 ./:/lyraBaichuan nvcr.io/nvidia/pytorch:23.02-py3

pip install -r requirements.txt
python demo.py
```

## Uses

```python
from lyra_baichuan import lyraBaichuan7B, lyraBaichuan13B

model_path = "./models/Baichuan2-13B-lyra"
tokenizer_path = "./models/Baichuan2-13B-lyra"
inference_dtype = 'fp16'
prompt = "登鹳雀楼->王之涣\n夜雨寄北->"

memopt_mode = 1
max_output_length = 64
arch = "Ampere" # Ampere or Volta
cuda_version = 12 # cuda version, we currently support 11 and 12

# To use 7B model, initialize with lyraBaichuan7B
model = lyraBaichuan13B(model_path, 
                        tokenizer_path = tokenizer_path, 
                        dtype = inference_dtype,
                        memopt_mode = memopt_mode,
                        arch = arch,
                        cuda_version = cuda_version)

bs = 1
prompts = [prompt, ] * bs
output_texts = model.generate(
        prompts, output_length=max_output_length,
        top_k=30, top_p=0.85, temperature=1.0, repetition_penalty=1.0, do_sample=False)

print(output_texts)
```
