Conceivably you could have a public-facing dashboard of the rollout status to reduce confusion or even make it visible directly in the UI that the model is there but not yet available to you. The fanciest would be to include an ETA but that's presumably difficult since it's hard to guess in case the rollout has issues.
Why would you be confused?
The UI tells you which model you're using at any given time.
I don't see what model I'm using on the Codex web interface, where is that listed?
