Summary

• What is new: LongRoPE extends the context window of pre-trained LLMs to 2048k tokens, a significant leap from the current limit of around 128k tokens.
• Why this is important: Extending the context window of large language models is challenging due to high fine-tuning costs, scarcity of long texts, and issues introduced by new token positions.
• What the research proposes: LongRoPE achieves the extension through a novel strategy involving non-uniform positional interpolation, a progressive extension strategy, and readjustment for short context performance.
• Results: Models extended with LongRoPE can handle up to 2048k tokens with minimal fine-tuning, maintaining performance at short context windows across various tasks on LLaMA2 and Mistral.
