Anthropic Ships 'Dreaming' Primitive: Asynchronous Between-Session Memory Consolidation for Agents — Modeled on Hippocampal Replay

Mem0·high signal

Anthropic's Dreaming primitive (shipped May 6, 2026) runs asynchronously between agent sessions, reviewing transcripts and memory stores to extract patterns, merge duplicates, and surface new insights. It's explicitly modeled on hippocampal memory consolidation — the biological process where the brain replays and organizes experiences during sleep. This moves agent memory from passive retrieval to active synthesis: instead of just searching past sessions, the agent discovers connections between them offline.
