To determine if a specific photo is AI-generated, the best approach is to use an AI image detector tool. These tools analyze pixel-level patterns, textures, and metadata to provide a probability score indicating whether an image was generated or altered by AI. They can recognize images from popular AI models like DALL·E, Midjourney, Stable Diffusion, and others. Such detectors are available for free online and provide instant analysis by uploading the image to the platform. The result usually includes a confidence score and sometimes identifies the specific AI model used, if any. This method is currently the most reliable way to confirm if a photo is AI-generated or not.

If you provide the photo, I can assist in checking it or guide on the use of these detection tools.
