Stable Diffusion 3 Medium release generates anatomically incorrect images

Stability AI released Stable Diffusion 3 Medium, an AI image generator, on June 12, 2024. Users on Reddit reported that the model produces mangled human anatomy, such as deformed hands and bodies. The failures are attributed to aggressive NSFW content filtering in the training data that removed images of human anatomy. The company has not responded to the criticism.
