# OpenWeights.com

> OpenWeights.com is an independent licensing desk for open-weight AI models. It explains which commercial license a company needs for a given open-weight model, based on its revenue, monthly users and region, and routes qualified license requests to the lab that publishes the model. OpenWeights.com does not sell or grant licenses itself; only the publishing lab can.

Open weights means a model's trained parameters are published for download. It is not the same as open source: the Open Source Initiative's definition of open source AI also requires the training and inference code and enough detail about the training data to rebuild a similar system. Many open-weight models ship under non-commercial, revenue-capped, user-capped or branding licenses.
