This has high priority as well. Do we want to start with GitHub Actions? I'm not an expert, but I can study the ecosystem a bit and come back to you in a few days. Anyway, it may be just better to evaluate the pipeline together to set up something robust and complete from the beginning.

Setting up actions is the easy part, the challenge is to write tests for a library that heavily relies on external resources. We could try to have a local install going via Ansible in a CI runner and check that the tests run there, but it kinda sounds like a nightmare.

Is there some way to bundle a "default" very very very small model that we can use for basic test functionalities? It doesn't need to be good, just small enough to work and produce testable output.
