Efficient training of language models to fill in the middle

OpenAI introduced a new training method for language models called 'fill-in-the-middle' that improves efficiency. This approach allows models to generate missing text in the middle of a passage rather than only predicting text sequentially. It matters because it enhances the model's ability to understand and generate more coherent and contextually relevant text.
