Open Source Model

Also known as: open model

An open-source model is an AI model released so that others can download, inspect, modify, or run it themselves.

An open source model refers to an AI model that has been released so that anyone can download, run, study, and modify it for their own purposes. If you compare it to cooking, you are not only selling the finished dish, but you are also making the recipe public so anyone can follow it and modify it.

It has attracted attention as an alternative to the monopoly of AI technology by a few big techs, and is widely used by companies to install it on their own servers and use it without worrying about data leaks or to fine-tune it for specific tasks. For researchers and startups, it provides a foundation for experimentation without expensive APIs.

Strictly speaking, the scope of disclosure varies from model to model. Some point out that it falls short of traditional open source software standards, as only the weights are disclosed and the training data or code is often kept private, and there are also licenses that place conditions on commercial use.
