A University of Texas paper finds that AI agents can gradually degrade in reliability after deployment—without any change to the underlying model—because real-world use causes context to grow through chat summarization and memory accumulation.

Claims

  • AI agents can become less reliable over time after deployment even when the underlying model remains unchanged.
  • Agents are typically evaluated at the time of deployment when they are fresh, not after extended real-world use.
  • Real-world agents continuously accumulate context through chat summarization and memory storage, which degrades performance.
  • Standard evaluation benchmarks fail to capture post-deployment performance degradation in agents.

Key quotes

AI agents can slowly become less reliable after deployment, even when the model itself does not change.
real agents keep changing because they summarize old chats, store more memories
