Train with classification/semantic segmentation instead of Object Detection

[taceroc]

Hi all,
I want to train a segmentation model, e.g predict a polygon surrounding certain objects. I found this in the documentation https://docs.roboflow.com/train/train, where it shows that there is “default” and a “classification/semantic segmentation” model types. I want to use the second option, but when I create a dataset and a version and go to the training options I do not see the segmentation, I only see the default (object detection), there is non option for the model type. Do I need to have a premium account to be able to use the segmentation model? or am I missing something?
Thank you
