The short answer
Usually, after a check. Might hold something you care about. Look inside before removing it.
What is it?
Keras downloads pretrained weights, for example for its built-in image models such as ResNet or EfficientNet, into ~/.keras/models. Each file ranges from a few MB to several hundred MB.
Pretrained weights downloaded by Keras. They download again on next use.
What happens if you delete it?
Weights are downloaded again the next time a script asks for that pretrained model.
How to remove it properly
Move the folder, or the files you no longer need, to the Trash in Finder (Go › Go to Folder… ~/.keras/models).
Quit the app that uses it, then move it to the Trash. Empty the Trash when you’re sure.
Before you delete it
Check that you did not save your own trained models in this folder; those cannot be downloaded again.
How MoreRoom helps
MoreRoom recognises this item and labels it “Review first”: it shows what’s inside, its size and last use, so you can decide. Nothing is removed without your say, and everything goes to the Trash first, with Undo.
Frequently asked questions
Is it safe to delete Keras models in ~/.keras/models?
Usually, after a check. Might hold something you care about. Look inside before removing it. Weights are downloaded again the next time a script asks for that pretrained model.
Will Keras model cache come back after I delete it?
Yes. Weights are downloaded again the next time a script asks for that pretrained model.
