## Model Card for lyraChatGLM

lyraChatGLM is currently the **fastest ChatGLM-6B** available. To the best of our knowledge, it is the **first accelerated version of ChatGLM-6B**.

The inference speed of lyraChatGLM has achieved **10x** acceleration upon the original version. We are still working hard to further improve the performance.

Among its main features are:

- weights: original ChatGLM-6B weights released by THUDM.
- device: lyraChatGLM is mainly based on FasterTransformer compiled for SM=80 (A100, for example), but a lot faster.
- batch_size: compiled with dynamic batch size, max batch_size = 8

## Speed

### test environment

- device: Nvidia A100 40G

|version|speed|
|:-:|:-:|
|original|30 tokens/s|
|lyraChatGLM|310 tokens/s|


## Model Sources

- **Repository:** [https://huggingface.co/THUDM/chatglm-6b]

## Uses

```python
from transformers import AutoTokenizer
from faster_chat_glm import GLM6B, FasterChatGLM


MAX_OUT_LEN = 100
tokenizer = AutoTokenizer.from_pretrained('./models', trust_remote_code=True)
input_str = ["为什么我们需要对深度学习模型加速？", ]
inputs = tokenizer(input_str, return_tensors="pt", padding=True)
input_ids = inputs.input_ids.to('cuda:0')


plan_path = './models/glm6b-bs8.ftm'
# kernel for chat model.
kernel = GLM6B(plan_path=plan_path,
               batch_size=1,
               num_beams=1,
               use_cache=True,
               num_heads=32,
               emb_size_per_heads=128,
               decoder_layers=28,
               vocab_size=150528,
               max_seq_len=MAX_OUT_LEN)

chat = FasterChatGLM(model_dir="./models", kernel=kernel).half().cuda()

# generate
sample_output = chat.generate(inputs=input_ids, max_length=MAX_OUT_LEN)
# de-tokenize model output to text
res = tokenizer.decode(sample_output[0], skip_special_tokens=True)
print(res)
```
## Demo output

### input
为什么我们需要对深度学习模型加速? 。

### output
为什么我们需要对深度学习模型加速? 深度学习模型的训练需要大量计算资源,特别是在训练模型时,需要大量的内存、GPU(图形处理器)和其他计算资源。因此,训练深度学习模型需要一定的时间,并且如果模型不能快速训练,则可能会导致训练进度缓慢或无法训练。

以下是一些原因我们需要对深度学习模型加速:

1. 训练深度神经网络需要大量的计算资源,特别是在训练深度神经网络时,需要更多的计算资源,因此需要更快的训练速度。
