LLM outputs can fail silently when they appear as valid JSON but violate the expected data schema, leading to downstream application crashes. Standard `json.loads` only checks for syntactic correctness, not semantic adherence to a required structure. Implementing schema validation, such as with Python's Pydantic library, after JSON parsing can catch these deviations early. A robust approach involves a retry loop with exponential backoff and logging to handle persistent validation errors, allowing for prompt tuning and preventing production failures. AI
IMPACT Developers need robust validation for LLM outputs to prevent downstream application failures caused by schema drift.
