What problem does it solve?

Extract structured data from LLM responses with Pydantic validation, automatically retrying failed extractions and ensuring type-safe parsing of JSON.

Core Features & Use Cases

  • Structured data extraction from LLM outputs with Pydantic schemas.
  • Automatic retries on validation failures with helpful feedback.
  • Streaming partial results for real-time processing of large outputs.
  • Multi-provider compatibility with a consistent API.
  • Build robust data extraction pipelines that convert free-form text into validated data models.

Quick Start

Provide a target Pydantic model and a prompt, then run the Instructor client to extract and validate structured data from your LLM response.

FAQPage Schema
How do I extract structured data from LLM outputs with Pydantic validation?

To extract structured data from LLM outputs, define a target Pydantic model and pass a prompt to the client. It enforces type-safe JSON parsing and validates the LLM response against your schema.

What happens when LLM structured data extraction fails validation?

When structured data extraction fails validation, the skill automatically retries the failed extraction. It provides clear error feedback to the LLM to ensure type-safe parsing on subsequent attempts.

Can I stream partial structured data results for real-time processing?

Yes, you can stream partial structured data results for real-time processing. This feature allows you to handle large outputs incrementally as the LLM generates validated data.

Does this Pydantic LLM validation tool support multi-provider pipelines?

Yes, the tool supports multi-provider compatibility with a consistent API. This allows you to build robust data extraction pipelines across different LLM providers without changing validation logic.

What is the best way to build robust data extraction pipelines from free-form text?

The best way to build data extraction pipelines is using a client that converts free-form text into validated Pydantic data models. This enforces type safety and handles validation failures with automatic retries.
