For creating high-quality images with controllable parameters, there are several open-source options. One is DeepMake, an AI content creation system that lets you generate high-quality images and videos, edit existing content and automate editing tasks without relying on cloud services or paying for usage. It has a range of abilities, including text-to-image generation, image-to-image generation, face and object masking, and image/video upscaling. DeepMake also can be integrated with popular VFX and video editing software like Adobe After Effects and runs on a variety of hardware.
Another good option is Stability AI, which has a range of generative AI models across image, video, audio and language domains. That includes Stable Diffusion 3 for text-to-image generation, Stable Video Diffusion for open generative video and Stable Audio 2.0 for high-quality music and sound effects. It has flexible membership options and can be self-hosted, so it's good for both individuals and businesses.
ZMO is another option, particularly if you want a very customizable and user-friendly interface. It's got tools for photorealistic portraits, anime-style images and compositing. ZMO has a reputation for high quality and regular updates, and it's popular with content creators, from pros to enthusiasts.
And then there's Stablecog, a free, multilingual, open-source AI image generator based on Stable Diffusion and Kandinsky models. You can generate art by describing the image or by starting with an existing image. It's got a range of customizable parameters and offers different pricing plans for different users. It's good for artists, designers and anyone curious about AI-generated art.
