Evaluators — Testing & Safety
Module 01 established LLMs are non-deterministic and can hallucinate confidently. This module is the engineering discipline that catches it — before your users do.
Learning objectives
- Beginner: Log evaluator failures without acting on them, to establish a baseline of how often your system produces off-topic or ungrounded answers before building automated handling.
- Intermediate: Return a safe fallback message on evaluation failure instead of the raw (possibly wrong) answer, without automatic retry.
- Advanced: Bounded automatic retry via Spring Retry for high-stakes endpoints specifically, combined with observability (Module 17) tracking evaluation pass/fail rates as a first-class production metric, not just an ad-hoc log line.
