MAML, Prototypical Networks and Reptile are distinct research methods; in-context learning is a related few-shot behavior evaluated in large language models, not the same training procedure.
Jin Dive
MAML learns an initialization that can adapt to a new task through a small number of gradient steps. Prototypical Networks form class prototypes in an embedding space and classify by distance. Reptile is a first-order algorithm that moves the initialization toward parameters learned on sampled tasks. Brown et al.’s GPT-3 paper evaluates in-context few-shot learning by placing demonstrations in the prompt without gradient updates. This is a behavioral analogy to fast adaptation, not a claim that GPT-3 was trained with the same meta-learning algorithm.

Splitting meta-training into tasks with support and query examples.
Using MAML’s task-specific inner loop to adapt an initialization.
Classifying examples by distances to Prototypical Network class centers.
Comparing Reptile’s first-order update with GPT-3’s in-context demonstrations, which use no gradient updates at inference.
