What problem does it solve?
Outlines solves the problem of unreliable, invalid, or schema-breaking LLM outputs by generating text that is structurally constrained to valid JSON, XML, regex patterns, or Pydantic-defined types.
Core Features & Use Cases
- Structured generation with guaranteed validity: Constrain decoding so outputs cannot violate the target structure (e.g., JSON shape, Pydantic schema, or regex).
- Type-safe Pydantic workflows: Generate directly into Pydantic models to get validated, typed results for downstream systems.
- High-performance local inference options: Use local backends such as Transformers, llama.cpp, or vLLM for efficient, production-oriented generation.
- Use Cases: Turn messy natural language into reliable data records (extraction), enforce constrained classification labels, or generate structured configuration/specs without post-hoc parsing failures.
Quick Start
Ask your AI to extract product details into a Pydantic model using the outlines JSON generator with a local Transformers or vLLM backend.
