As an industry, I wish we would stop calling these things "open weight" because it is too easy to confuse with actual "open source", which they are not. Photoshop source code+ OSI license = open source Photoshop binary you can run on your own computer = open weight Photoshop SaaS web app = closed, proprietary (Opus, GPT, etc.) "Open weight" models are still just binary blobs that are completely inscrutable. It's like…
Photoshop binary you can run on your own computer = open weight
I don't think this is a correct analogy. You are not allowed to distribute modified versions of the Photoshop binary. Most open weight model licenses allow you to make and distribute your own finetunes, etc.
