RoPE at the End of Its Rope? Theory, Diagnosis, and Mitigation of Long-Context Failures

Long-context failures of RoPE-based language models can arise from RoPE's intrinsic tradeoff between maintaining stable token preferences and distinguishing nearby positions. Determining which weakness to address, and how, requires a more precise characterization of RoPE's behavior in trained models across context leng...
