Yes, on the main BI settings (Gear Icon) tabs, under AI, you may notice that BI has "found" all of the custom models (ipcam-animal, ipcam-combined, ipcam-dark, ipcam-general, license-plate, etc...). Without any further instructions, it will try to analyze every trigger against ALL of the models available, potentially adding a lot of time and CPU load to every trigger.
Here in the dialog box you show, it allows you to define a subset of those to be run by CPAI for the specific camera and profile you are currently looking at. You might for example want ipcam-combined in the daytime , but switch to ipcam-dark for the nighttime profile, or potentially add the ipcam-animal model to either (or both) profiles, saving analysis time and CPU load. Or, any single model or combination that makes sense to you in your application.
