01

Choose your models

Pick the models you trust — flagship-only, budget coders, or a different set per key. Set a price ceiling, or leave it open.

02

Point your SDK

Change one base URL. Any OpenAI-compatible client works unchanged — chat, completions, streaming.

03

We route to the cheapest offer

Every request goes to the lowest live price among your models. The response headers tell you exactly what you paid.

# your existing code — one line different

    api_key="sk-mag-…",
)
r = client.chat.completions.create(
    model="auto",  # cheapest model in your set, right now
    messages=[…],
)
