modelrouter
what it is
modelrouter is one api that sits in front of every major ai model — claude, gpt, gemini, open models, plus specialized ones for images, ocr, and code. you send a single request and it picks the right model for the job and the cheapest tier that can actually do it. every provider's keys live in a fastly secret store at the edge, never in the app or on the phone. that's exactly what makes it humankind's security layer: the app's ai features call modelrouter instead of calling model vendors directly, so api keys, spending limits, and user data never sit on the device or get handed to any single vendor.
why it matters
an app can use the best model for each task without being locked to one company, without leaking credentials, and without surprise bills — and i can swap the model underneath at any time without ever touching the app.
