UTILMEM is a new diagnostic benchmark that tests how conversational agents use long‑term memory, focusing on reasoning over dense histories, spotting implicitly relevant memories, synthesizing distributed evidence, and resisting interference from similar distractors. It contains 1,717 instances across five domains and evaluates a range of retrieval‑based and memory‑augmented systems. The study shows that strong performance on traditional factual recall does not guarantee effective memory utilization, highlighting a gap between retrieving information and integrating it into coherent, task‑oriented outputs.
RealCompanion is a benchmark that evaluates an AI companion’s ability to understand a human over long, real-world conversations. It consists of ten real relationships with 27,218 messages spanning up to 120 days, along with derived files such as a profile, persona, chat ground truth, and a question set that cites the relevant messages. The study finds that past context is rarely needed, memory detection is challenging, and agent systems vary widely in cost while achieving similar persona reconstruction.

MIRAGE is a controlled study that examines how multimodal personal agents use historical evidence when conversation state changes. The study keeps evidence, questions, and scoring constant while varying only the conversation state, then checks if agents can determine answerability, recover the correct source, and answer from it. Results across seven multimodal backbones show distinct failure regimes before and after compaction, heavy reliance on context continuity by open-weight models, and mixed effects of retrieval pressure on source attribution.
