The article discusses the evolution of AI language models, specifically focusing on GPT-3, GPT-3.5, and ChatGPT. It starts by introducing the concept of generating long sequences with sparse transformers to address the issue of increasing time complexity. The authors propose factorized attention and a residual architecture to reduce computation and time while maintaining efficiency. The article then explores the idea of language models as few-shot learners, highlighting the need for meta-learning to train generalized models. In-context learning, inspired by GPT-2, is discussed as a method for training language models to quickly adapt to new specific tasks with minimal demonstrations. The article provides links to relevant papers for further reading.
