Outlines

Python-type-driven structured generation through a provider-independent application interface.

Overview

Research summary

Outlines is a Python library for generating structured outputs from language models. Developers describe the expected result using Python types, Pydantic models, or other supported constraints and invoke compatible model backends through a shared interface. Its structured-generation approach helps applications produce machine-readable values instead of repeatedly repairing arbitrary text responses. Integration details and supported constraints depend on the backend. The Apache-2.0 repository is maintained by the .txt team; the vendor also offers separate commercial structured-generation products.
