EverMemOS

An AI agent that forgets everything when a session ends has to start cold every time, and that is the gap EverMemOS tries to close.

EverMemOS is an open-source AI memory infrastructure from EverMind that gives agents continuous long-term memory and a persistent identity across sessions.

EverMind calls it a memory application processor for reasoning and growth.

For developers, EverMemOS offers a modular, extensible framework with hierarchical memory extraction and dynamic organization of what an agent has stored.

A related component, EverMemModel, handles parametric long-context understanding, which goes beyond standard RAG setups.

EverMind reports state-of-the-art results on the LoCoMo and LongMemEval-S memory benchmarks, and it publishes EverMemBench so others can evaluate memory systems.

EverMemOS is entering beta on a new cloud platform, with the Memory Genesis Competition 2026 launching alongside it.

Expect to work with infrastructure directly rather than a finished app.
