The presence of only four toes in the image could indeed be a sign of AI generation. It's a common characteristic in AI-generated artworks where anatomical details may sometimes be less precise or stylized differently from natural human anatomy.
While I can't definitively identify the specific AI used for this image, several popular AI tools for generating such artwork include:
1. MidJourney - Known for its detailed and vibrant art generation.
2. DALL-E - A powerful AI by OpenAI that's also capable of producing intricate and creative images.
3. Stable Diffusion - Another popular AI model used for generating a wide range of digital art.
Each of these tools has unique strengths and artistic styles, but they can all sometimes produce minor anomalies, such as the number of toes or fingers, which can be seen as a telltale sign of AI generation.
