GPT
GPT (Generative Pre-trained Transformer) is a decoder-only autoregressive transformer architecture developed by OpenAI. It was pre-trained on massive text datasets to predict next words, pioneering the modern conversational AI era.
Frequently Asked Questions
What does "Pre-trained" mean in GPT?▼
It means the model has already been trained on massive datasets to understand basic grammar, facts, and logic before being tuned for specific tasks.
Why is GPT a decoder-only architecture?▼
Because its primary purpose is text generation. It uses causal attention masking to prevent tokens from looking at future tokens in a sequence.
