What problem does it solve?
Outlines provides a disciplined approach to generating structured outputs (JSON, Pydantic, and regular-expression constrained text) from LLM prompts, ensuring outputs conform to schemas and are easier to validate.
Core Features & Use Cases
- Constrained token sampling via grammar-based generation (CFG/FSM) to guarantee valid outputs.
- Structured generators for JSON, Pydantic, and regex outputs, with backends that support local models (Transformers, llama.cpp, vLLM).
- Pydantic integration and automatic schema translation for type-safe results; practical use cases include data extraction, form processing, and multi-entity extraction.
- Backed by a flexible architecture enabling production-grade workflows and zero-overhead validation.
Quick Start
Load a local model with outlines and generate a typed JSON output from a prompt describing the data you need.
