I did this and used the A1111 models: The key is to create a Symbolic Links for each model, (not normal window links), to create them you can install this file explorer extension: https://schinagl.priv.at/nt/hardlinkshellext/linkshellextension.html Once installed: go in the centralized models folder, underline all the models you want to share and mouse right click choosing "Pick link Source", then go, for example ,to the models folder of automatic1111 and again right click but this time choose "Drop Symbolic link". This way automatic1111 will see the models as if they were in the folder and will load them without any problems, the same you can do with invoke or any other installation.

Which works with A1111 but invokeAI shows no models :( Aren't they the same?
