Jet-Long: Efficient Long-Context Extension with Dynamic Bifocal RoPE

Abstract

Jet-Long is a tuning-free method for extending the context length of large language models. It combines a local RoPE-faithful window with a dynamically rescaled long-range window and an efficient attention implementation, preserving short-context behavior while supporting longer inputs without retraining.
