OUTLINES
Guaranteed structured outputs from any LLM
Apache-2.0
ABOUT
LLM applications often break because models return malformed JSON, inconsistent fields, or free-form text that downstream code cannot parse safely. Outlines enforces structure during generation instead of cleaning outputs afterward, helping developers eliminate brittle regex fixes, repeated retries, and post-processing code when they need dependable structured responses.
INSTALL
pip install outlinesINTEGRATION GUIDE
1. Generate valid JSON objects from LLMs for production APIs and backend workflows
2. Constrain model output with regex or grammar rules for extraction, classification, and parsing tasks
3. Build information extraction pipelines that return predictable typed data instead of free-form text
4. Standardize structured generation across providers such as OpenAI, Ollama, and vLLM
