In this article, we will guide you through the process of utilizing a powerful text generation model based on the GPT-2 architecture tailored for the Korean language. Whether you are a seasoned developer or a curious beginner, this user-friendly guide will help you interact with the model seamlessly!

Model Configuration

The text generation model we will be using is structured as follows:

• Model type: GPT2 (Flax, Pytorch)
• Number of Layers: 12
• Hidden Dimension: 768
• Intermediate Size: 3072
• Attention Heads: 12
• Vocabulary Size: 51200
• Maximum Sequence Length: 1024
• Total Parameters: 125M

To put this into perspective, think of a library. The structure of our model is like the building itself, with various sections (layers) that hold a plethora of books (parameters). Each layer offers a different perspective, contributing to our understanding of the language model.

Performance Benchmarks

Data Used for Training

The model was trained on a diverse set of datasets, enriching its language understanding capabilities:

• AIHub SNS Conversations (730MB)
• AIHub Colloquial Speech (422MB)
• AIHub Books (1.6MB)
• AIHub Large Web Data-Based Korean Corpus (12GB)
• Korean Wikipedia (867MB)
• Namuwiki (6.4GB)
• National Language Institute Messenger Conversations (21MB)

• Written Language Corpus (3.2GB)
• Spoken Language Corpus (1.1GB)
• News Corpus (17GB)
• Citizen Petitions from the Blue House (525MB)

The total number of tokens used is approximately 7 billion.

Example Usage

Here is a simple code snippet to get you started with the model using Python:

from transformers import pipeline
model_name = "heegyuajoublue-gpt2-base"
pipe = pipeline("text-generation", model=model_name)

print(pipe("안녕하세요", repetition_penalty=1.2, do_sample=True, eos_token_id=1, early_stopping=True, max_new_tokens=128))
print(pipe("오늘 정부 발표에 따르면,", repetition_penalty=1.2, do_sample=True, eos_token_id=1, early_stopping=True, max_new_tokens=128))
print(pipe("싸늘하다. 가슴에 비수가 날아와 꽂힌다.", repetition_penalty=1.2, do_sample=True, eos_token_id=1, early_stopping=True, max_new_tokens=128, min_length=64))

In this code, we are importing the necessary libraries and defining the model pipeline. Then, we provide some text input, and the model will generate responses accordingly. Think of it as having a conversation with a well-read friend who has a wealth of information at their fingertips!

Troubleshooting Tips

If you encounter any issues while using the text generation model, consider the following troubleshooting steps:

• Ensure that all dependencies are installed and up to date.
• Verify that you have correctly specified the model’s name.
• If you receive errors during model execution, check for mistakes in your code syntax.
• Check the model documentation for any version-specific notes.
