About Language models are few-shot learners
GPT-3 (Generative Pre-trained Transformer 3) is a 175 billion parameter autoregressive language model introduced by OpenAI in the paper 'Language Models are Few-Shot Learners' presented at NeurIPS 2020. The model demonstrates that scaling up language models significantly improves task-agnostic few-shot performance, often rivaling or exceeding state-of-the-art fine-tuned models on a wide range of NLP tasks. Key contributions include in-context learning (few-shot, one-shot, zero-shot) without gradient updates, and a detailed analysis of model size and performance.

FAQ
What does 'few-shot learner' mean in the context of GPT-3?
It means GPT-3 can perform tasks given only a few examples in the input prompt, without any gradient updates or fine-tuning, by learning from the context provided.
How many parameters does GPT-3 have?
GPT-3 has 175 billion parameters, making it one of the largest language models at the time of publication.
What was the main research question addressed by this paper?
The paper investigates whether scaling up language models (to 175B parameters) improves in-context few-shot learning performance across a wide range of NLP tasks.
