I don't understand why so many people call Stable Diffusion open source.

View on HN

Why do you think it is not open source? The model weights, model architecture, and dataset are all available.

Read the license of the model: https://github.com/Stability-AI/stablediffusion/blob/main/LI...

5. and 7. make it not open source

Seems like it is open source, just not free software.

It's not free software or open source. Check the Open Source Definition: https://opensource.org/osd

I don't see how it contradicts the open source definition at https://opensource.org/osd, could you point it out for me?

For the most blatant violation, look at point 6 of the OSD and attachment A of the license.

Open source is more than just everything being available. It also depends on the license, and the one Stable Diffusion uses doesn't qualify, for multiple reasons, including the one mentioned upthread.

You can download the model weights and run them offline. At least, you could in v1.4. I assume this is still possible on v2.0?

Right, but the model weights are arguably not the "source code", and the license gives the users fewer rights than open source licenses do.

I think the controls in this space are such a shit show right now that being "open model" is practically equivalent to a WTFPL.

If you're trying to build an app based on SD, then not being open source matters. But seems like the majority of use cases are just "I want to run the model locally". And at that point HF can't stop me from just ripping the Wi-Fi card out of my computer.
