dottxt-ai/outlines: Structured Outputs

Outlines is a library for structured outputs for LLMs that guarantees valid structure during generation rather than fixing outputs after the fact.
It works with any model and supports provider independence across OpenAI, Ollama, vLLM, and others.
Users specify the desired output type directly, such as Literal values, ints, or Pydantic models, and Outlines produces matching structured data.
The quickstart shows installing the package, connecting it to a transformer model, and generating simple typed outputs like sentiment labels and integers.
Outlines demonstrates real-world uses including customer support triage, e-commerce product categorization, and parsing incomplete event data into structured records.
The examples show that structured outputs can automate routing, inventory updates, and other downstream workflows without fragile parsing logic.
