microGPT: Building GPT from scratch

microGPT is a lightweight implementation of the Generative Pre-trained Transformer (GPT) model for natural language processing tasks. It is designed to be simple and easy to use, making it a great option for small-scale applications or for learning and experimenting with generative models.

Features

  • Lightweight implementation of the GPT models
  • Trained on a small scaled diverse dataset (6 GB)
  • Designed to be trained on consumer GPU (RTX 4060 8GB)
  • Small number of parameters (82 Million!)
  • Customizable hyperparameters for model configuration
  • Supports Top K Top P filtering and temperature scaling
  • Written in Python with PyTorch as the deep learning framework

300k iterations of training

Installation

  1. Clone the repo and run pip install -r requirements.txt

Usage

  1. Run tokenizer/train_tokenizer.py to generate the tokenizer file. The model will tokenize text based on it.
  2. Run datasets/prepare_dataset.py to generate dataset files.
  3. Run train.py to start training~

Modify the files stated above if you wish to change their parameters.

Usage (Inference)

To edit model generation parameters, head over inference.py to this section:

# Parameters (Edit here):
n_tokens = 1000
temperature = 0.8
top_k = 0
top_p = 0.9
model_path = 'models/microGPT.pth'

# Edit input here
context = "The magical wonderland of"
