Question: Is there a service that offers free AI-generated art creation with unlimited base model usage?

If you're looking for a service that offers free AI-generated art creation with unlimited base model usage, Makeayo is a good option. It's got a user-friendly interface that doesn't require much technical expertise, and you can generate images with no extra cost for unlimited generations. It also offers HD upscaling to 4k resolution, pose matching, and access to hundreds of models from a community of generative art enthusiasts. Makeayo is available for Windows 10 and 11, with Mac and Linux support coming soon.

Another good option is Playform, a no-code AI art generation platform with tools like FaceMix, Train AI, Style Transfer and Upscale. It guarantees that all the art you create is your intellectual property, and it's private by default. It doesn't charge for unlimited generations, but you pay when you download or sell your results. That means it's a good option for creative exploration and production without a big budget.

The service works on the web and on mobile devices, and it's got a community with daily AI Art challenges and the ability to share your work. NightCafe is designed to be accessible to people of all skill levels, so it's a good option for interesting art.
