A developer encountered an issue where an LLM, Gemini Flash-Lite, incorrectly interpreted expiration dates on product labels, defaulting to the first of the month instead of the last day when only the month and year were provided. To address this, the developer opted to handle the date calculation in code rather than relying on prompt instructions due to concerns about LLM probabilistic outputs. This led to the challenge of effectively testing prompt changes, which was solved by using PromptProof, a platform designed for statistically validating LLM prompt accuracy by allowing users to create datasets, annotate ground truth, and run prompt experiments. AI
