The training set is a one time computation though, running the model still costs cycles and people have to pay for it (see sites like Hugging Face or GooseAI).

The training set is a one time computation though, running the model still costs cycles and people have to pay for it (see sites like Hugging Face or GooseAI). What people are asking about is the code itself and the one time computed training set. They're not asking to run the trained model for free. Anyway, getting cycles isn't too hard, expect CoreWeave or another compute-centric company to hop on board in due course.
