FAQ
What is the first step in measuring AI agent behavior improvement?
The first step is to define what better behavior means for the AI agent, based on its specific job and goals.
Why is establishing a baseline important when measuring AI agent improvements?
A baseline provides a reference point to compare the agent's performance before and after changes, ensuring that improvements are measurable and meaningful.
What metrics are recommended for evaluating AI agent performance?
Recommended metrics include task success rate, retry rate, planning iterations, cost per successful task, and error/regression rate.
How does Reflexio contribute to AI agent improvement?
Reflexio helps AI agents learn from real interactions, corrections, and successful outcomes, enabling them to reuse useful learnings and improve behavior over time.
What should teams consider when deciding to keep or roll back an improvement?
Teams should evaluate whether important outcomes improve, costs remain acceptable, and existing capabilities still work, while also checking for any new issues introduced by the change.
