Also known as: Generative Pretrained Transformer 3
A 175-billion-parameter autoregressive Transformer language model notable for strong few-shot and zero-shot performance across diverse NLP tasks.
DESCRIPTION
GPT-3 popularized large-scale in-context learning by demonstrating strong performance without task-specific fine-tuning. It is trained to predict the next token on diverse web-scale corpora. Developers access GPT-3 via APIs for text generation, summarization, and question answering. Its capabilities sparked widespread applications and research in prompt design. Limitations include hallucinations, bias, and sensitivity to prompt phrasing. GPT-3 influenced subsequent models, including instruction-tuned variants and GPT-4. It remains a foundational reference for scaling laws and few-shot learning.
ALTERNATIVE DEFINITIONS
arXiv
We train GPT-3, an autoregressive language model with 175 billion parameters, which we show can achieve strong performance on many NLP tasks in the zero-shot, one-shot, and few-shot settings.
Stresses scale and few-shot capabilities across tasks.
OpenAI
We demonstrate that scaling up language models greatly improves task-agnostic, few-shot performance, sometimes even reaching competitiveness with prior state-of-the-art fine-tuning approaches.
Emphasizes scaling and task-agnostic few-shot performance.
