Open-weight models make their trained parameters available for download, but that does not necessarily mean every part of the AI system is open or that all forms of commercial use are unrestricted.

Under the Open Source Initiative’s Open Source AI Definition, an open-source AI system should allow users to use, study, modify, and share it for any purpose without seeking permission. OSI’s definition also requires access to information about training data, relevant code, and model parameters.
