# weblab-10b

# Overview
This repository provides a Japanese-centric multilingual GPT-NeoX model of 10 billion parameters.

* **Library**
    
    The model was trained using code based on [EleutherAI/gpt-neox](https://github.com/EleutherAI/gpt-neox).

* **Model architecture**

    A 36-layer, 4864-hidden-size transformer-based language model.

* **Pre-training**

    The model was trained on around **600B** tokens from a mixture of the following corpora.

    - [Japanese C4](https://huggingface.co/datasets/mc4)
    - [The Pile](https://huggingface.co/datasets/EleutherAI/pile)

# Benchmarking

* **Japanese benchmark : JGLUE 8-task (2023-08-27)**

    - *We used [Stability-AI/lm-evaluation-harness](https://github.com/Stability-AI/lm-evaluation-harness/tree/2f1583c0735eacdfdfa5b7d656074b69577b6774) library for evaluation.*
    - *The 8-task average accuracy is based on results of JCommonsenseQA-1.1, JNLI-1.1, MARC-ja-1.1, JSQuAD-1.1, jaqket_v2-0.2, xlsum_ja-1.0, xwinograd_ja, and mgsm-1.0.*
    - *model loading is performed with float16, and evaluation is performed with template version 0.3 using the few-shot in-context learning.*
    - *The number of few-shots is 3,3,3,2,1,1,0,5.*
    - *special_tokens_map.json is modified to avoid errors during the evaluation of the second half benchmarks. As a result, the results of the first half benchmarks became slightly different.*

# How to use the model

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

tokenizer = AutoTokenizer.from_pretrained("matsuo-lab/weblab-10b")
model = AutoModelForCausalLM.from_pretrained("matsuo-lab/weblab-10b", torch_dtype=torch.float16)

if torch.cuda.is_available():
    model = model.to("cuda")

text = "吾輩は猫である。"
token_ids = tokenizer.encode(text, add_special_tokens=False, return_tensors="pt")

with torch.no_grad():
    output_ids = model.generate(
        token_ids.to(model.device),
        max_new_tokens=100,
        do_sample=True,
        temperature=0.7,
        top_p=0.95
    )

output = tokenizer.decode(output_ids.tolist()[0])
print(output)
