Structured Output ≠ Usable Results
mattjcoles · reddit · 2026-07-14
This article discusses how structured output only guarantees the "shape," not the "content", and therefore cannot be directly used to decide whether to merge code.
The author's approach involves layering multiple components:
- Using Pydantic AI on Bedrock for structured output
- Using Pydantic evals for evaluation
- Pairing it with a calibrated LLM judge
The goal is to turn model outputs into results that can genuinely "gate merge," rather than merely checking if the JSON format is correct.
