All local (customer premises)
Models and tools run on hardware you control in your building or private rack.
Compute
Your servers / workstations / on-prem GPU
Data egress
Typically no — prompts, documents, and audio stay on your network (except tools you connect outward).
Who can access
Your admins, your physical security; DRP only if you grant remote ops access.
Voice on this tier
STT/TTS can run fully on-box (e.g. local Whisper + local vocoder). No audio to third-party voice APIs unless you enable them.
