# stockmark/stockmark-13b

Stockmark-13b is a 13 billion parameter LLM pretrained from scratch based on Japanese corpus of about 220B tokens. This model is developed by [Stockmark Inc.](https://stockmark.co.jp/)

Please see our [blog](https://tech.stockmark.co.jp/blog/202310_stockmark_13b/) for more details.

This project is supported by [AWS LLM development support program](https://aws.amazon.com/jp/local/llm-development-support-program/).

## How to use

```python
import torch
from transformers import AutoModelForCausalLM, AutoTokenizer

# For A100 or H100 GPU
model = AutoModelForCausalLM.from_pretrained("stockmark/stockmark-13b", device_map="auto", torch_dtype=torch.bfloat16)

# If you use a T4 or V100 GPU, please load a model in 8 bit with the below code.
# To do so, you need to install `bitsandbytes` via `pip install bitsandbytes`.
# model = AutoModelForCausalLM.from_pretrained("stockmark/stockmark-13b", device_map={"": 0}, load_in_8bit=True)

tokenizer = AutoTokenizer.from_pretrained("stockmark/stockmark-13b")

inputs = tokenizer("自然言語処理とは", return_tensors="pt").to(model.device)
with torch.no_grad():
    tokens = model.generate(
        **inputs,
        max_new_tokens=128,
        do_sample=True,
        temperature=0.7
    )
    
output = tokenizer.decode(tokens[0], skip_special_tokens=True)
print(output)
```
