Model Description

japanese-stablelm-base-beta-7b is a 7B-parameter decoder-only language model based on Llama-2-7b that has been fine-tuned on a diverse collection of Japanese data, with the intent of maximizing downstream performance on Japanese language tasks.

For an instruction-following model, check Japanese-StableLM-Instruct-Beta-7B. The base and instruct models are also available in larger 70b sizes. For a model that has faster inference times, see Japanese-StableLM-Base-JA_Vocab-Beta-7B, or the instruction-following version.

Usage

First install additional dependencies in requirements.txt:

pip install -r requirements.txt

Then start generating text with japanese-stablelm-base-beta-7b by using the following code snippet:

import torch
from transformers import AutoTokenizer, AutoModelForCausalLM

model_name = "stabilityai/japanese-stablelm-base-beta-7b"
tokenizer = AutoTokenizer.from_pretrained(model_name)

# The next line may need to be modified depending on the environment
model = AutoModelForCausalLM.from_pretrained(model_name, torch_dtype=torch.float16, low_cpu_mem_usage=True, device_map="auto")

prompt = """
AI で科学研究を加速するには、
""".strip()

input_ids = tokenizer.encode(
    prompt,
    add_special_tokens=True,
    return_tensors="pt"
)

# this is for reproducibility.
# feel free to change to get different result
seed = 23  
torch.manual_seed(seed)

tokens = model.generate(
    input_ids.to(device=model.device),
    max_new_tokens=128,
    temperature=0.99,
    top_p=0.95,
    do_sample=True,
)

out = tokenizer.decode(tokens[0], skip_special_tokens=True)
print(out)

We suggest playing with different generation config (top_p, repetition_penalty etc) to find the best setup for your tasks. For example, use higher temperature for roleplay task, lower temperature for reasoning.

Training Dataset

Roughly 100B tokens from a mixture of the following corpora were used for continued pre-training.

Use and Limitations

Intended Use

The model is intended to be used by all individuals as a foundation for application-specific fine-tuning without strict limitations on commercial use.

Limitations and bias

The pre-training dataset may have contained offensive or inappropriate content even after applying data cleansing filters which can be reflected in the model generated text. We recommend users exercise reasonable caution when using these models in production systems. Do not use the model for any applications that may cause harm or distress to individuals or groups.
