RouterPlus provides AI inference and LLM routing, allowing users to manage and optimize multiple AI models based on their own evaluations.

RouterPlus is a platform designed for managing and optimizing AI model inference, particularly for large language models (LLMs). It allows users to route requests to various closed and open-weight models using a single API key. The platform emphasizes data compliance, regional routing, and production-grade service level agreements (SLAs). A core feature is its routing mechanism, which is based on a user's specific evaluations and production traffic rather than global benchmarks. This enables teams to compare and select models that best fit their workload, optimizing for both quality and cost. RouterPlus supports reserved capacity for future inference needs and allows users to connect their existing provider accounts. The platform includes an 'Optimize' feature to compare candidate models against a baseline using held-out evaluation cases, deploying only when quality and cost checks are passed. It does not store prompts or completions, only usage metadata, with data policies handled by the respective model providers.
