GPT-2
Common model (pretrained) for text generation developed by OpenAI. GPT-2 is open source.
GPT-3
Further development of GPT-2 (see above). Both models use approximately the same architecture, but GPT-3 has more layers (see neural network) and has been trained with more data.
GPU
Graphics Processing Unit / Graphics Card. Graphics cards offer very high computing power and are therefore used for training deep learning models.
