FAQ

Does UltraThink support persistent sessions?

No, sessions are stored in-memory only and will be lost when the server restarts or terminates. For persistent sessions, you would need to implement custom session persistence.

How does UltraThink handle confidence tracking?

UltraThink supports confidence scoring on a 0.0-1.0 scale with optional uncertainty notes. Users can specify their confidence level for each thought and track assumptions with confidence values.
