Agent Memory Systems Survey
Summary
A panoramic survey (2026.03) of 30+ agent memory projects across 15 dimensions - standalone memory frameworks plus agents' built-in memory - including LongMemEval scores. Notably documents the trend of agentic/observational memory overtaking pure vector memory.
Key Takeaways
- 30+ projects compared across 15 dimensions - ideal checklist fodder
- Documents the field's shift away from vector-only memory
- Benchmark scores (LongMemEval) ground the comparisons
