How to Detect When an AI Assistant Starts Returning Empty Answers

An AI service can return an empty or nearly empty answer while requests appear successful. The issue may follow a response parser change, token limit, safety filter, or tool output formatting shift.

What to check

Track response body length, completion status, model and prompt version, tool calls, safety outcomes, and downstream parsing. Compare affected requests with a known-good release using privacy-safe examples.

Recommended next step

Alert on empty responses by task and version, provide a clear retry or human fallback, and add regression checks for structured and tool-assisted responses.
