Negative Guidance minimum sigmaĪllows the sampler to skip the negative prompt when it theoretically doesn't matter. InvokeAI - For some reason incredibly slow for me. In my experience it's the least memory leak averse optimization, so you can keep SD running for longer before you have to restart it.

The article will get expanded as I amass more knowledge. Nevertheless, this post has been made from the perspective of AMD RX 580 (8GB) owner.
