Bad news for that: it is only free for noncommercial use, and this isn't just a temporary early-release thing, but the new general direction for StabilityAI:
I mean the fact SD has shown its possible just means that other research groups can also use the same concept...
Someone on Reddit was actually pointing towards a model thats more narrow in scope to SDXL but that was trained by a single guy on an A100, so no reason we can't expect other groups to pop up or maybe a consortium of freelancers from the fine tuning community to maybe get together to start there own base model.
The barrier is really being lowered and this is beautiful.
What a great time to be alive.
