Upgrading the model is pretty easy. We just need to build the new model locally in the same way we build the current model. This usually takes fewer than 2min. If people want to deploy the new version to web browser and share for others to use, they just need to upload the model weights to some server (for example we are now using a public Hugging Face repo to store the weights), and provide a link pointing to the weights. This can be achieved also with little effort.
What happens when someone wants to update/upgrade the model to a newer version? Can they just get a “diff” and “patch” their model, or do they have to download a whole new one?
