Abstract
Long-term memory for an assistant: the highest published score on LoCoMo, reading about a fifth of the context of the systems next to it. The scores and the context each one read are public. The library, its design and its run log are not. The subject itself is taught from zero in the book AI Agent Memory: Novice to Ninja. Other systems' figures are as their vendors published them, each with its own answering model and judge. None is reproduced here, so the comparisons are context and not a ranking.
