Suitable tasks
Provide a common interface for authorized models. Define users, available connections and documents each group may access.
Limits and checks
Self-hosting the interface does not automatically make all processing local. External connections, tools, extensions and document sources may transmit data.
A repeatable trial
Install a test instance, connect one engine and create two accounts with distinct permissions. Check conversation and document access, then test engine failure and backup restoration.
How to decide
Adopt this arrangement when connections and operating responsibilities are explicit. Evaluate updates, backups and permissions before increasing user numbers.
Frequently asked questions
Is the interface the model?
No. It uses a separately configured engine.
Why test two accounts?
To verify access separation.
What should I back up?
Configuration and data needed for restoration, according to your installation.
