It avoids the catastrophic forgetting associated with direct fine-tuning and provides a cost-effective pathway for continuous knowledge updates.<\/p>\n<h2>The challenge of updating LLM memory<\/h2>\n<p>Large language models are frozen after training and their internal knowledge remains static until they undergo subsequent, computationally massive updates. <\/p>\n<p class=\"text-utility-meta-010 text-ink-subtle mt-2\">Comparison of different LLM memory frameworks (source: arXiv)<\/p>\n<p>Currently, developers rely on three main approaches to integrate external knowledge into an LLM, each with distinct drawbacks:<\/p>\n<p>Non-parametric methods, such as retrieval-augmented generation (RAG) and in-context learning, retrieve relevant documents from an external database and insert them directly into the model&#8217;s prompt. While popular, these methods are limited by context window sizes.\u00a0<\/p>\n<p>As Armando Solar-Lezama, a co-author of the paper, told VentureBeat, \u201cVector databases have a fundamentally difficult job of encoding the full semantics of a chunk of text in a single vector, and then match that vector to a query, even when the relevance of the chunk&#8230; may only be apparent in the context of other chunks.\u201d\u00a0<\/p>\n<p>The researchers note that the semantic similarity of embeddings often does not correspond to what a user&#8217;s query actually requires. Processing thousands of retrieved tokens also creates substantial computational overhead and inference latency.
