A new paper explores the costs and effectiveness of using precomputed memory in language models. Researchers found that while precomputed memory can save computational resources by avoiding repeated context feeding, it degrades when assembled from separate parts and may not incorporate corrections served alongside it. The study suggests that for deployed systems, precomputed memories should be rebuilt frequently to stay current with new information, with warm-rebuilding trained compressions of key-value caches or serving specific updates showing promise.
