Experiential

Experiential is an open source gateway and router for agent workflows. Hosted models, models you bring keys for, and models running locally all sit behind one OpenAI-compatible API, and on top of that you set who can use which model, for which use case, and how much they may spend. The part that makes it more than a proxy is what it does with the traffic: production requests become the training signal for a custom router or model tuned for quality, speed and cost. Python, Apache-2.0.
