Overview

Tired of wrestling with unpredictable Large Language Model (LLM) outputs? Outlines is your revolutionary solution for guaranteed structured generation. Unlike traditional methods that rely on fragile post-generation parsing, Outlines ensures that your LLM's output conforms to your desired structure during the generation process. This means no more headaches from broken JSON, inconsistent data, or complex regex. Seamlessly integrate structured outputs for any LLM, from OpenAI and Cohere to vLLM and Ollama, with a simple, Pythonic API that mirrors your existing type system.

Key Features

• Guaranteed Structured Outputs: Directly generate data that strictly adheres to your specified types (e.g., int, Literal["Yes", "No"], Pydantic models, Enums) without post-processing.
• Universal Model Compatibility: Write your code once and run it across a wide range of LLMs and providers, including OpenAI, Ollama, vLLM, Hugging Face Transformers, and more.
• Effortless Integration: Simply pass your desired output type to the model call (model(prompt, OutputSchema)).
• Provider Independence: Switch LLM providers without modifying your generation code.
• Dynamic Prompt Generation: Leverage Jinja-based templates for reusable and customizable prompts, ideal for tasks like few-shot learning.
• Robust Real-World Examples: Explore practical applications for customer support triage, e-commerce categorization, event parsing, document classification, and function calling.

Typical Use Cases

Outlines is built to tackle common LLM challenges by enforcing structure and predictability:

• Automated Data Extraction: Extract specific fields like product attributes, customer details, or event information into well-defined schemas.
• Content Classification: Reliably categorize documents, emails, or user feedback into predefined categories.
• API Interaction: Generate structured arguments for function calls, enabling seamless integration with other services and applications.
• Data Validation and Sanitization: Ensure that LLM-generated data meets strict format and type requirements before downstream use.
• Streamlined Workflows: Automate complex tasks by transforming unstructured text into actionable, structured data for efficient processing.
