Facts (curated)

Model access
Hosted APIs and partner programs — not on-prem inference by default.
What they do “more” vs QVAC
Tooling maturity, global latency, integrator ecosystem — at the cost of on-device data sovereignty.

Pros

  • Operational reliability and speed for teams that need to ship immediately.

Cons / risks

  • Prompts and telemetry sit in vendor-controlled environments — not a local-first stack like QVAC.
