9 min · Reviewed 2026
The premise
Instructor validates LLM JSON against Pydantic models and retries with the validation error as feedback.
What AI does well here
Define strict schemas
Set sensible retry budgets
Surface validation errors
What AI cannot do
Make a weak model intelligent
Fix ambiguous schemas
Replace business validation
