GPTune
Early GPT-2 fine-tuning tooling with practical presets for custom text generation.
GPTune is an early GPT-2 fine-tuning repository built soon after OpenAI’s GPT-2 release. It packaged a practical command-line workflow for training and sampling custom text generators before today’s LLM tooling had become standardized.
The project demonstrates hands-on experience with large language model adaptation under the constraints of the time, including single-GPU training, dataset preparation, sampling modes, optimizer choices, and reproducible scripts for fine-tuning the 774M-parameter GPT-2 model.
