Stability AI has announced a new image upscaler, an AI-based tool that can give your photos up to 4x bigger resolution. The company behind the somewhat controversial Stable Diffusion promises that the new tool can increase your images and not compromise their sharpness in the process. In fact,they claim that it could even improve it.
“Since the emergence of digital imagery, it has been nearly impossible to expand small images into larger ones without compromising the quality of the image,” Stability AI writes in the statement. Indeed, we could only see it in detective TV series and movies. But those movies are now a reality even for regular Joe and Jane editing their photos at home. “Now users can pass a small image into the API and get back one with more than double the level of detail,” the company writes.
Stability AI has released two open-source models behind the Image Upscaling API. The first is Real-ESRGAN, which doubles the resolution of a typical 512×512 image in only half a second. The second is the “latent” Stable Diffusion 4x Upscaler. It’s a little slower, but still pretty fast, upscaling your images in 20 to 40 seconds, providing more detailed results with a richer texture.
“The introduction of these models aligns with our vision to continuously enrich the Image Upscaling API with state of the art models as they become available,” the company writes. You’ll find all documentation to start using the APIs here. You can also get a Stability plugin for Photoshop and generate and edit images using both Stable Diffusion and DALL-E 2 right inside Photoshop.
