👤

✓Drop-in enhancement for existing LLM client code — add response_model parameter and get validated Pydantic objects back
✓Automatic retry with validation feedback: when extraction fails, error details are fed back to the LLM for self-correction
✓Streaming partial objects let you render structured data incrementally as the LLM generates, not just after completion
✓Works with all major providers: OpenAI, Anthropic, Google, Mistral, Cohere, Ollama — same API across all
✓Minimal abstraction layer — no framework lock-in, no workflow engine, just structured outputs on existing clients

⚠Focused exclusively on structured extraction — not a general-purpose agent or orchestration framework
⚠Retry loops can be expensive: each validation failure triggers another full LLM call with error feedback
⚠Complex nested Pydantic models with many optional fields can confuse smaller LLMs, requiring model-specific tuning
⚠Limited documentation for advanced patterns like streaming unions, parallel extraction, and custom validators

While currently free, pricing models can change. Instructor may introduce paid tiers in the future as they expand features.

Instructor offers core ai agent builders features at no cost. Paid alternatives may provide more advanced functionality or premium support.

Instructor may have usage limitations, reduced support, or be supported through other revenue streams. Always check the terms of service.

It's completely free — no credit card required.
