Ok, I've rewritten nostr:npub102ca8pnhy26vh2akepgr4vleyew65nuzug5val3sycslfe0wruwqzezyfp . it will web backed on https://sinkin.ai/ (SaaS - stable diffusions based models)
Paid users will be able to specify a model (listed on sinkin).
As far as I can see, the images generated are not as good as midjourney, but with a bit of practice and a good model, you can get decent results.
