Hi Laura,
Handling non-deterministic JSON outputs from LLMs is frustrating. I build production-grade agentic pipelines with strict schema enforcement.
Stack:
- Instructor / Outlines library for constrained decoding.
- Automatic schema validation fallback with few-shot error prompting.
- Unit tests validating against edge case documents.
Can deliver a working demo pipeline by tomorrow.
Best,
Alex
