Unify is an AI tool that serves as a single access point to various Language Models (LLMs). It automatically routes prompts to the optimal LLM endpoint, optimizing for speed, latency, and cost efficiency. Users can establish their own parameters and constraints regarding cost, latency, and output speed, and define their own custom quality metrics to personalize routing based on their needs. The tool refreshes data every ten minutes, systematically sending queries to the fastest provider based on the latest benchmark data for the user's region. Through a process of constant optimization, Unify ensures peak performance and varied quality responses by channeling multiple LLMs. The tool can be easily integrated with existing systems using a standard API key, meaning developers can call all LLMs across all providers with a single API. This enables them to tackle optimization problems that may otherwise be daunting, providing visibility and control over cost, accuracy, and speed.
