You can use /statusline to configure the status line to display fast mode status if you would like.

Hello @etraut-openai you have misread!
"Fast mode" cannot be controlled -- enabled or disabled !
It is not only about is not showing in the status-line!

Ah yes, I misunderstood. Reopening.

Make sure you haven't disabled the fast_mode feature flag in your config.toml file.

Also, not all models support the fast ("priority") service tier. Which model do you have selected?
