10 open-source projects that give AI agents persistent memory beyond the context window
CurieuxExplorer · x · 2026-09-28
- A curated list of 10 open-source projects that give AI agents persistent, cross-session memory, arguing that a million-token context window still leaves agents starting from zero every session.
- Highlights: Mem0 (66K+ stars, production-grade drop-in memory layer; its new algorithm scores 92.5 on LoCoMo with 7K tokens and 1s p50 latency), Hindsight (retain→recall→reflect), memU (memory as knowledge), Cognee (documents/code/conversations into knowledge graphs), Graphiti (tracks how facts change over time), OpenViking, Letta and Letta Code (memory + identity across sessions), and OpenMemory.
- Useful for choosing a memory infrastructure when building stateful agent applications.
