Adding to an existing language model

If I wanted to add to an existing model how would I do that? I have topic specific language from scientific domains that I would like to add.

I didn't see anything in the open or closed tickets.

Thanks!

The issue does not name any files, tests, or entry points. Start by surveying the repository's Python training scripts to determine whether adding domain-specific material to an existing model is supported; done would require a clear, documented workflow or an agreed implementation scope.
