I have an app that needs to generate hundreds and eventually thousands of images. What tools can I use to generate these images at scale. After I figure that out, then I will be looking at Rubbrband for quality control.
There's a few companies that provide APIs for image-gen. Personally I've been using the Kandinsky model off Replicate. It's really high quality, I'd recommend it: https://replicate.com/ai-forever/kandinsky-2.2
If you've got an nvidia graphics card with 8GB of vram made in the last decade, AUTOMATIC1111's stable diffusion web ui [1] will crank out a few thousand images every 24 hours. Depending on settings and how fast your card is, naturally.
And there's a large ecosystem of downloadable models available online for specific looks and concepts, like models trained for photorealism.
