GPT-2 Base Thai

GPT-2 Base Thai is a causal language model based on the OpenAI GPT-2 model. It was trained on the OSCAR dataset, specifically the unshuffled_deduplicated_th subset. The model was trained from scratch and achieved an evaluation loss of 1.708 and an evaluation perplexity of 5.516.

This model was trained using HuggingFace's Flax framework and is part of the JAX/Flax Community Week organized by HuggingFace. All training was done on a TPUv3-8 VM, sponsored by the Google Cloud team.

All necessary scripts used for training could be found in the Files and versions tab, as well as the Training metrics logged via Tensorboard.

How to Use

As Causal Language Model

from transformers import pipeline

pretrained_name = "flax-community/gpt2-base-thai"

nlp = pipeline(
    "text-generation",
    model=pretrained_name,
    tokenizer=pretrained_name
)

nlp("สวัสดีตอนเช้า")

Feature Extraction in PyTorch

from transformers import GPT2Model, GPT2TokenizerFast

pretrained_name = "flax-community/gpt2-base-thai"
model = GPT2Model.from_pretrained(pretrained_name)
tokenizer = GPT2TokenizerFast.from_pretrained(pretrained_name)

prompt = "สวัสดีตอนเช้า"
encoded_input = tokenizer(prompt, return_tensors='pt')
output = model(**encoded_input)
