Building production-grade Large Language Model (LLM) applications requires significant prompt engineering effort, including prompt creation, testing, and refinement, which can be time-consuming and lack collaboration. Existing solutions often lack centralized management, version control, and automated evaluation capabilities, hindering the development of high-quality LLM outputs.

Latitude is an open-source prompt engineering platform designed to streamline the development of production-ready LLM applications. It provides a centralized hub for prompt management, enabling teams to collaboratively write, iterate, and version prompts. The platform offers a playground for testing prompts at scale, along with tools for logging and debugging requests. Latitude supports automated evaluations using LLM-as-judge, code, or human feedback, and includes a refiner that automatically suggests prompt improvements based on evaluation results. By centralizing prompt engineering workflows and automating key tasks, Latitude reduces iteration time and improves the quality of LLM application outputs.
