Summarizing https://arize.com/blog/lost-in-the-middle-how-language-models-use-long-contexts-paper-reading/

Here's my try:

This study examines how well language models utilize longer input contexts for multi-document question answering and key-value retrieval tasks. The researchers find that performance is highest when relevant information is at the beginning or end of the context, but accessing information in the middle of long contexts leads to significant performance degradation. Even explicitly long-context models experience decreased performance as the context length increases. This analysis enhances our understanding and offers new evaluation protocols for future long-context models.
