A joint Illinois and Tsinghua University study finds that LLM agents have unreliable memory that degrades further when agents iteratively rewrite their own stored memories through self-reflection.

Claims
- LLM agents can learn from experience, but the memories they rewrite often become unreliable.
- Memory reliability in LLM agents worsens when agents repeatedly self-reflect and overwrite prior memory entries.
- Unreliable agent memory is an identified systemic problem for autonomous AI systems, not just an edge case.
Key quotes
LLM agents still have unreliable memory and that it can get worse when they keep rewriting their own memories.
LLM agents can learn from experience, but their rewritten memories often become unreliable.
