The platform

One key to every model. Everything else orbits it.

At the centre is one gateway that speaks to every model. Around it is everything built on it: agents that run, remember and pay; data they can search; pictures, voice, video, music and 3D; proofs anyone can check; open markets; and models that answer on your own device.

Models and routing

Every model through one OpenAI compatible API, routed by price, speed and measured quality.

4 live

Last 24 hours: 100% of 60 requests answered, median first token 630 ms over 56 timed. What this counts: the requests this gateway handled, plus a scheduled test request to a few low cost models from well known labs. A failure on our side or the upstream's counts against it. A request refused for its own mistake, such as a bad body or an empty balance, is not counted, and neither is an answer from the cache.

Last 24 hours: the gateway took a median of 69 ms before asking the model, and 444 ms at the 95th percentile, over 21 requests. This is the x-antimatter-overhead-ms header every answer carries.
