Open-source AI

AI released under terms that let anyone use, study, change and share it for any purpose. Its makers also release everything needed to do so. That means the model's weights, all the code used to build and run it, and a detailed description of the data it was trained on. The data itself is often copyrighted or private, so the description says where it came from and how to get it. In everyday use, the term also covers open-weight models, for which only the weights are published, often with limits on their use.
