Practical overview
When it fits
Use microGPT when you want hands-on access to a compact GPT implementation and its training or inference settings, especially for learning and small-scale experiments.
Who it is for
- Learners exploring how GPT language models are constructed.
- Developers experimenting with small-scale language-model training and text generation.
- Python users who want to modify model or sampling parameters directly.
Documented uses
- Prepare tokenizer and dataset files for a training run.
- Train the included GPT model using the documented scripts.
- Generate text from a supplied context and tune token count, temperature, top-k, or top-p.
- Modify the model configuration and training parameters for experiments.
Requirements & limits
The project is a public GitHub repository with an MIT license. The documented workflow runs from a local repository using Python scripts and installed requirements.
- The project is self-hosted code rather than a documented hosted generation service.
- The README describes an 82-million-parameter model and a 6 GB training dataset.
- Generation settings, including temperature, top-k, and top-p, are edited in
inference.py. - The repository points to microGPT-deploy as a separate project for web-app deployment.
Check current requirements in the official documentation. Source-based guidance does not mean OpenViST has run or independently tested this project.
Set up the documented training workflow
Prepare the tokenizer and dataset files, then start model training.
Before you start
- A local copy of the microGPT repository
- Python package dependencies installed with
pip install -r requirements.txt
Steps
Clone the repository and install its requirements.
Run
tokenizer/train_tokenizer.pyto generate the tokenizer file.Run
datasets/prepare_dataset.pyto generate dataset files.Run
train.pyto start training.
Expected outcome
The documented training script starts after tokenizer and dataset files have been prepared.
Guide limitations
- The README describes an RTX 4060 with 8 GB of memory as a target consumer GPU, but does not guarantee performance on other hardware.
- Training completion time and results are not specified.
Configure text generation in inference.py
Set the context and sampling parameters used by the documented inference script.
Before you start
- A local copy of the microGPT repository
- A model file at the path configured in
inference.py
Steps
Open
inference.pyand locate its generation parameters.Set the token count, temperature, top-k, top-p, and model path.
Edit the context string that will prompt generation.
Expected outcome
The inference script is configured with the chosen context and generation settings.
Guide limitations
- The README documents parameter editing but does not provide a complete command for running inference.
- The configured model path must correspond to the model file used.
