Extract validated structured data reliably

Extract structured data from LLM text using Pydantic validation and retry logic

Extraction tasks where you want automatic validation and retry without building your own harness.

• · prompt
• · Pydantic model class
• · raw LLM response

• · validated structured object

• · instructor
• · pydantic>=2.0
• · LLM API

Pydantic model well-defined; LLM supports function calling or JSON mode

Model validation fails on unexpected LLM output; retry loop infinite on unconstrained prompt

• · Pydantic integration
• · Function-calling fallback
• · Retry with backoff
