Language Models are Few-Shot Learners (GPT-3)
GPT-3 trains a 175-billion-parameter Transformer on a filtered Common Crawl plus other corpora, keeping the next-token objective but scaling roughly 100x over GPT-2. Given a natural-language instruction and a handful of demonstrations in its context window, it performs translation, question answering, arithmetic, and other tasks without weight updates, with accuracy generally rising as more examples are shown. This removed the per-task fine-tuning and labeled-data requirement for many uses and made prompting the primary interface to large models.
