Software or technology that is made freely available to the public, allowing anyone to view, modify, and distribute its source code. In the context of AI, open source projects often involve AI algorithms, libraries, or frameworks that are developed collaboratively by a community of researchers, developers, and enthusiasts. Recently, there has been a noticeable uptick in the emergence of open source models, reflecting a growing trend toward openness and collaboration in the AI community.
