Yes, true the fine-tuning is not new and indeed I also view it as "starting with an incredibly well-initialized network"

However, the promotable aspects of those vision models are completely new. You can define your tasks at runtime and steer the model behavior. I think this makes it easier and faster to insights from your images. Lastly, those models are trained on a lot of different tasks compared to previous models that were general classifiers and that could then be trained on a specific domain. This allows them for example to be reused in an organisation and prevents you from creating multiple task-specific models
