Pretty big difference. An open weight model is a model that you can run on your own machine. You just download and it’s yours to host and use. You don’t need to have anyone host it on their own backend for you, the entire model is available to you to do that on your own. What you don’t have is any control over or access to anything related to how the model was trained. You don’t know what kind of data they used to train it, and how exactly they used that dataset. If you did, that’d be an open source model.






Who’d a guessed a ginormous and expensive public infrastructure project that requires meticulous long term planning and the acquisition of literally thousands of privately owned pieces of land (often through long and expensive legal processes, sometimes spanning various different jurisdictions) takes longer than bolting a couple thousand plastic boxes onto poles, or building what’s essentially a large-ish industrial facility?
