Question: I'm looking for an image generation API that can produce high-resolution images from text prompts, ideal for graphic design and content creation.

For generating high-resolution images from text prompts that are useful for graphic design and content creation, getimg.ai is a top contender. The service offers a variety of tools, including an AI Generator for creating original imagery, Image to Video conversion, and AI Canvas for extending imagery beyond its original boundaries. It can generate high-resolution imagery and offers a variety of community-trained AI models, so it's good for creative tasks like architecture and art.

Another strong contender is Shutterstock ImageAI, which marries the text-to-image diffusion model technology with Shutterstock's large library of images. The model is designed to generate high-resolution photorealistic images, and you can fine-tune it with tools like DBRX and MPT. Shutterstock's vetted image library means you can expect consistent high quality, and it's good for content creation and visualization.

Leonardo also can generate high-quality imagery, including with AI Canvas for refining designs and 3D texture generation. It's good for a broad range of creative uses, from concept art to product photography, and offers both free and paid accounts depending on your needs.

Last, Aitubo offers a full suite of tools, including an AI image generator based on Stable Diffusion 3 for photorealistic imagery. It also can handle more advanced tasks like background removal and AI outpainting, so it's good for creative types like game developers and animators.
