What runs on premise and what does not?

Many platforms describe themselves as supporting on-premises deployment while requiring external calls for the part that matters. The question worth asking is whether the prompt leaves the environment, not whether the application does.

Centralpoint treats on-premises, private cloud and public cloud as first-class deployment modes. Embedded local models — Llama, Qwen and ONNX — run inside the organization's infrastructure, so where that configuration is used, no prompt crosses the boundary. 451 Research attributed this posture to serving regulated clients that cannot route data through external services. The environment requires Microsoft infrastructure, and updates ship every two weeks across every deployment mode.
