Diffusers is a Mac app that uses models from the Hugging Face Hub to generate images from a text description of what the user wants. It is optimized and converted to Core ML for maximum performance, and does not require credits for online services. It offers a variety of settings, including different models, prompts, negative prompts, seeds, and steps, to help users achieve their desired images. It is open source, and privacy is guaranteed as images are never sent outside of the user's computer.
