Praxis Cloud's model capacity is purchased directly from [Volcano Engine](https://www.volcengine.com) and [Ant Group](https://www.antgroup.com).

For an infrastructure company, who the upstream is is not a detail. If we provide model capacity to developers and enterprises, we have to guarantee that the supply is legitimate, traceable, and sustainable — not quotas pieced together from intermediaries of unknown origin.

Choosing first-tier vendors as direct upstreams is part of the reliability commitment: behind every model call made on Praxis Cloud stands a clear supplier with service guarantees.
