A: Subscribr uses many different models under the hood to provide the various features of the app.

However, for scriptwriting you can actually choose which model to use! Details here: https://help.subscribr.ai/article/35-choosing-your-draft-writing-model

Note that Sonnet has been updated to 4.0 - I need to mention that in the docs.

Generally when a new version of one of these frontier models comes out, I make it available in the app immediately.
