I missed the train on getting free monthly credits for midjourney. Are there any free ai image prompt sites?

i pay for MJ because i am very rich 😎 (actually i just have bad self control and will enter my card on any site that promises me a tiny droplet of happiness)

Yes! Bing Image Creator is totally free and used DALL-E. It's a one and done kinda deal, you're not tweaking and getting as specific as some others, but you will get some amazing results with shorter prompts like "draw a realistic hamster putting out a fire with a hose, with a city background"

Thanks, it worked. I see a 100 counting down with each image I create. Will it get replenished automatically?
- Ah, so Bing will only let you go so far with the AI, which is 30 messages, up from 20. This is really just to stop things going too far I believe, as the tech really is nuts. It'll also often catch itself getting too lewd or whatever and cut itself off. Bing AI is way more "out there" than some others
Thanks for the suggestion - I just tried this and made a pretty cool image for my latest Pathfinder character!

I run Stable Diffusion locally. It's free but you need a nice video card though.

Any news of like a llama.cpp equivalent for SD? It would be handy to be able to slowly run it without a GPU, and maybe competitive with other free options in terms of images generated per day.
- No idea what a llama.cpp is.

You can use Stable Horde to prompt from a collection of volunteers running Stable Diffusion. This is a nice front-end for it
Those who contribute to the horde get credits to obtain results faster, so there is a queue (currently 3-4 minutes)

Came here to say that. We also have multiplex other UIs so you can find the one that works best for you. 4 minutes might also be pushing it, even for anonymous. You can make an account however and go much faster. And you can easily get a lot more kudos by contributing to the community
I myself use Patience.ai. Although I'm not sure what kudos do.

The queues are mostly on popular models (anime, photorealistic, the like), so perhaps you want to use more niche models (Supermarionation? Can't believe it exists). Also instead of showing time estimation, Patience.ai would show your queue number instead (322nd image in queue).
Another vote for the AI Horde people. They seem to be a legit volunteer operation not about to turn startup, and the kudos economy they are running is pretty neat and well thought out.

It's not a site, but automatic1111 has a webui you can run on your computer that works pretty well.

Craiyon is free to use but every prompt takes around one minute and upscaling as well.

You weren't kidding about the time! What's nice is that I don't need to sign up. Thank you!
That’s dalle mini, right? Last time I used it it only produced nightmarish images lol. Maybe it’s better now?
- I just tried it, and it's not as good as the others, but it's not nightmarish.

NightCafe is not exactly free, but you get to claim 5 credits everyday. Generating images cost 1 credit or more depending on model and steps. You can accumulate credits. It's much better than 15 credit monthly of DALL-E.
Mage.Space is free for StableDiffusion models, but offers paid upgrade to access other advanced models and NSFW art.
B Discover is a mobile app that could generate AI images for free as well.
Craiyon has been mentioned here, it is also free, although the generation time can take quite long (they offer paid upgrade for this), and the results are often not pretty. Each resulting image is also watermarked with Craiyon logo in the corner. However I must admit that Craiyon model is very accurate, whatever weird prompt you give it will try to obey, instead of just giving generic pretty images.

avi.ai is free so far

I'm getting an error trying to submit a prompt. " Failed to generate images due to: SyntaxError: JSON.parse: unexpected character at line 1 column 1 of the JSON data " Any idea?
- It's finiky sometimes I just gotta come back later and it works fine
