Amazon Paper: Matching Fine-Tuning to KV-Cache Policy Prevents Long-Context Failures
eyishazyer · x · 2026-08-31
A new Amazon paper reveals that KV-cache policy isn't just an inference optimization; it dictates the necessary training regime. If an LLM will forget parts of its context during inference due to sparse attention, it must be trained to forget that way as well. The study shows that matching fine-tuning to the KV-cache policy can prevent failures in long-context tasks.
