In-context learning implicitly performs gradient descent within the forward pass.

Transformer attention layers implement…Transformer attention layers implement an implicit gradient descent algorithm, with in-context learning performance scaling predictably with model size — doubling parameters improves few-shot accuracy by 5-8% on average.

Context & Methodology

This theoretical result explains why few-shot prompting works: the model literally learns from examples during inference, without any weight updates.
