Cooperative Memory Paging with Keyword Bookmarks for Long-Horizon LLM Conversations

Ziyang Liu

Cooperative paging with keyword bookmarks lets LLMs recover evicted conversation turns on demand and achieve higher answer quality than full context or retrieval methods.

Claims

C1strongest claim

On the LoCoMo benchmark (10 real multi-session conversations, 300+ turns), cooperative paging achieves the highest answer quality among six methods -- outperforming truncation, BM25, word-overlap retrieval, a search-tool baseline, and full context -- on four models (GPT-4o-mini, DeepSeek-v3.2, Claude Haiku, GLM-5), confirmed by four independent LLM judges (p=0.017, paired bootstrap).

C2weakest assumption

That keyword bookmarks supply enough distinctive information for the model to correctly trigger and select the right page via the recall() tool, given the reported 57% correct selection rate when bookmarks lack specificity.

C3one line summary

Cooperative paging replaces evicted LLM context with keyword bookmarks and adds a recall tool, outperforming six other methods on the LoCoMo benchmark across four models with statistical significance.
