## Description New users may not understand the syntax that `%ai` and `%%ai` expect and may run it without a model ID. In #1437, this currently shows the following response: <img width="1437" height="874" alt="Image" src="https://github.com/user-attachments/assets/8595dc13-f3d4-4fc9-93c0-3e7d6d9b8a85" /> ## Expected behavior A simpler error message that just tells the user to specify a model ID.
