Question: I'm looking for a platform that enables me to create custom AI models for image synthesis using my own images.

If you want a platform to build your own AI models for image synthesis, using your own imagery, getimg.ai is a good option. It lets you generate new images from text prompts, edit existing images and train your own AI models. Among its features are DreamBooth for training your own AI models and ControlNet for guiding AI generation. It can generate high-resolution images and has a credit-based pricing system with flexible levels.

Another option is AIEasyPic, which lets you generate professional photos from text prompts and train your own AI models on your own imagery. It comes with an AI image editor for fine-tuning details and offers real-time image generation with different styles. It's geared for graphic designers, digital artists and content creators, with pricing levels to suit different needs and budgets.

Facet is another option, particularly if you want a collaborative browser-based tool. It can generate and edit images in real time, using spatial prompts and auto-enhanced image prompts. Facet is geared for pros who want to control the creative process but still take advantage of AI's abilities, with pricing levels that can accommodate different use cases.

If you're more of an artist, OpenArt converts text-to-image prompts into lovely images and comes with a variety of AI drawing and editing tools. You can create your own styles and models, too, so it's good for artists of all skill levels. OpenArt's tiered pricing system is geared for different levels of use, from casual to pro.
