Last week, researchers from UCL's Centre for Artificial Intelligence and Huawei Noah's Ark Lab published Memento, a framework demonstrating that agents can achieve state-of-the-art performance through sophisticated external memory without fine-tuning the underlying language model. This methodology achieved remarkable benchmarks — all while using 50-80% fewer computational resources than traditional fine-tuning approaches. Here's why this matters for the future of Agentic AI.
