Following a recent change, we have received a few questions about this on Discord. What happened is that you were part of a group that was beta testing something (The Assistant, Ki, or something else), and due to that you had access to the Assistant despite not being on the Ultimate plan.
Kagi is hoping to provide its Pro subscribers with access to the Assistant but limiting that to the cheaper LLMs (as it the case in the picture you sent) due to having to keep things sustainable cost-wise. Your account is in a rare state where you have early access to those models despite the feature not being fully live yet. I have pinged you on Discord in the relevant thread if you'd like to read more.
