Hello!

1. Is the limit on custom model training - per month? Meaning, we can create x number of custom models monthly? Or is the limit the "active" custom models? Meaning, we can create new ones, but we have to delete the previous ones to free-up slots?

2. If we purchase additional credits for custom model training, how will that affect our LTD credits? Do they just stack?

3. If Imagen5 comes out in the future, will Imagen4 become available to lower tier LTDs?

Thank you.
