LLM context-removal methods may mostly hinge on how much of the prefix they keep, one post suggests
The author calls this a cleaner motivation for “prefix sliding” than the one in their own linked paper, “Prefix Sliding for efficient test-time scaling.”
TLDR
One post suggests that sophisticated methods for removing past context from large language models—known as “KV-cache eviction”—seem to mostly come down to how much of the prefix, or beginning of the context, they preserve. The author sees that observation as a cleaner motivation for prefix sliding than the rationale in their own paper.
