Yes, there is a certain queue for the free service. If too much is generated, the longer the wait time is. The SDXL Turbo model has a manageable cost because it is generated faster.
I assume your plan is to just hope that Stability.AI doesn't bother using you? Clearly this is a commercial service.
Huh, TIL: "STABILITY AI NON-COMMERCIAL RESEARCH COMMUNITY LICENSE AGREEMENT"
I learned. I will be replacing the model soon. I haven't looked too closely at the license.
Yeah, I know. I'm not doing anything profitable with the model, but of course if I wanted to commercialize it, I'd apply for a license from stability.ai
