Question: Is there an image generation engine that offers customizable dimensions and fast generation speeds?

getimg.ai offers a full-fledged AI-powered image creation and editing service. It's got an AI Generator for creating images from text prompts and a Real-Time AI Generator for fast creation. You can set dimensions and create high-resolution images, too, which is useful for architectural and artistic uses.

Another top contender is SDXL Turbo, which uses a technology called Adversarial Stable Diffusion Distillation to generate high-resolution images from text prompts. It can generate photorealistic images in 207ms, which is fast enough for real-time applications like video games and virtual reality. SDXL Turbo also lets you set dimensions and generate images relatively fast, so you can get high quality and high performance.

If you want a free service that's easy to use, ImgGen is a good option. You can generate high-resolution images up to 4096 x 4096 pixels without signing up or adding a watermark. ImgGen also comes with a suite of photo editing tools, so it's good for creative and professional use. Its speed and high resolution make it a good general-purpose tool.
