It shows that when two domains share an observational bottleneck but require incompatible optimal actions, any uniformly near-optimal policy must induce distinct memory distributions at that bottleneck. The result yields a separation theorem: sufficiently successful agents cannot rely only on current state observations, but must preserve domain-relevant information in memory. The paper further shows that if an agent's memory contains enough information to estimate values for related goals, then that memory can be used to approximately reconstruct the agent's local transition dynamics. Together, these results characterize memory as the substrate that supports domain disambiguation, transition-model reconstruction, and planning for generalist agents.", "url": "https://wpnews.pro/news/what-must-generalist-agents-remember", "canonical_source": "https://arxiv.org/abs/2606.18746", "published_at": "2026-06-18 04:00:00+00:00", "updated_at": "2026-06-18 04:23:07.930798+00:00", "lang": "en", "topics": ["artificial-intelligence", "machine-learning", "ai-agents"], "entities": ["arXiv"], "alternates": {"html": "https://wpnews.pro/news/what-must-generalist-agents-remember", "markdown": "https://wpnews.pro/news/what-must-generalist-agents-remember.md", "text": "https://wpnews.pro/news/what-must-generalist-agents-remember.txt", "jsonld": "https://wpnews.pro/news/what-must-generalist-agents-remember.jsonld"}}
