Outlines is a .txt product that guarantees structured outputs from LLMs by letting developers specify a desired output type, ensuring the generated data matches a defined structure. It is model- and provider-agnostic, running the same code across OpenAI, Ollama, vLLM, and more, with a simple integration pattern: model(prompt, output_type). The platform targets structured generation for use cases like customer support triage, e-commerce product categorization, event detail parsing, and document classification, and offers schema auditing to verify compliance and structure during generation, currently in early access.
