What are the best practices for monitoring a deployed model and when should I retrain or replace a model?

Performance decay over time/ Model drift is a common phenomenon for many agentic use cases.

Tips for Post-Deployment Model Monitoring and Retraining

Here is a step-by-step way to think about monitoring and logging data that can be leveraged to continuously improve and refine underlying models powering the agentic AI applications:

  • Instrument logging at each interaction: record user queries, agent responses, user feedback, runtime stats, reasoning steps.
  • Track model metrics (accuracy, latency, error rates) and business KPIs (conversion rate, task success).
  • Define alert thresholds to trigger retraining or update workflows when metrics degrade significantly.
  • Automate evaluation pipelines: periodic validation on new datasets promotes pipeline retraining.
  • Use model distillation pipeline to swap in smaller models when cost vs. performance trade‑offs are favorable
