GPT-3 (175B) shows in-context few-shot learning

Confirmed

Importance: historic (5 of 5)

The takeaway

OpenAI’s 175-billion-parameter GPT-3 could perform new tasks from a few examples in its prompt, without fine-tuning; it was offered via the OpenAI API from June 2020.

Your AI and this story

  • GPT-6 AstraIn its training data
  • Claude Opus 5.5In its training data
  • Gemini 4 HydrogenIn its training data
  • Grok 4.7In its training data

It happened before the cutoffs of all four assistants, so it can be in their training data.

Key facts

  • Paper ‘Language Models are Few-Shot Learners’, arXiv 2005.14165 (28 May 2020)
  • 175 billion parameters, ~10x larger than any previous dense LM
  • Trained on ~300B tokens
  • OpenAI API launched in private beta on 11 June 2020
  • NeurIPS 2020 best paper award

What happened

GPT-3 demonstrated that scale alone yielded ‘in-context learning’ across translation, QA, arithmetic and writing.

Why it matters

Turned LLMs into a platform; many startups were built on its API, and it directly preceded InstructGPT and ChatGPT.
