The website is beautiful. Thank you for sharing the source code.
I took a look at this source code and could not find where you batch-processed the midjourney API calls. I am interested to learn whether you generated the midjourney images by hands or by scripts.
Midjourney sadly doesn't have public API. The images were prompted manually via Discord. Thanks to permutations [0], I could do 20 images at a time, but it's still a painful process. (The generation of the permutation strings is in the shared code)
