Lycore builds a custom LLM evaluation runner inside Django to prevent silent prompt regressions. The system addresses a routine prompt tweak that misclassified edge cases for 4 days without triggering standard unit tests. The runner executes exact-match and model-graded evaluations against a JSON fixture file.
Unit tests cannot catch semantic drift; LLM features require dedicated evals Founders building LLM features must implement semantic evaluation suites early to prevent silent prompt regressions from breaking production workflows.
