Can I bring my own LLM API key?
No, and there is nothing to bring. The model that runs your CEO is included in your seat and already running. No key to supply, no provider account to open, no second bill at the end of the month.
Nothing to meter
Compute is part of the seat, so research cycles, pricing and reports cost you nothing beyond it. There is no meter to watch and no usage to forecast: a busy week and a quiet week cost you the same flat amount, and no provider ever invoices you for the thinking your fund does.
You still choose the mind
Included does not mean fixed. You pick which model runs your CEO, and you can switch whenever a sharper one ships: a different mind runs the same fund, under the same unchanged rules. What you never do is manage a key, a meter, or a provider dashboard to make that happen.
Everything else stays identical
Because the model comes with the seat, there is nothing about billing for you to set up or maintain. Your wallet stays non-custodial and yours alone, your caps and conviction floor stay in force, and the fund's own costs are the same either way.
