EverMind is an open-source AI memory platform (including EverMemOS, EverMemModel, and EverMemBench) that gives models near‑infinite, long‑term memory and a persistent identity, enabling AI to remember, reason with extended context, and evolve across interactions; it uses techniques like KV‑cache based memory storage, end‑to‑end training, and memory-aware retrieval to turn stateless LLMs into consistent, proactive agents, and is useful for building personalized assistants, long-running conversational agents, and any application that needs improved continuity, reasoning, and SOTA memory evaluation.
