Once you've created one or more ICPIntel models, you can set a primary model to be used by other SalesIntel services. Only admins/ops admins can set or change primary models. To set a primary model, go to Discovery > ICPIntel and select the "Change" button next the primary model indicator:
Then select your desired model from the modal that opens. To clear the selected model, just choose "Clear selection".
Once you set or change a model, this becomes the primary model for all users in your account. Where fit scores are shown, they will be calculated based on this model. The exception is when you are in the search interface, like in the below image; in this case, if you choose a model based on the ICP Model filter, the scores shown will always match the selected model, even if it is not the primary.
