Open-weight model
An open-weight model is a model whose trained parameters (the weights) are published, so you can download and run it yourself. That is not the same as open source: the licence decides what you may do with it, and the training data and code are often not shared. Always read the licence before you build on one.
Definitions are general and kept short on purpose. Check the vendor documentation or the regulation for the details of your case.
