Why do AI images sometimes have weird hands?
AI models struggle with hands because:
- Complexity: Hands have many possible configurations and positions
- Training data: Hands appear in various positions, making patterns harder to learn
- Occlusion: Hands are often partially hidden in training images
- Latent space: The compressed representation has limited capacity for fine details
To improve hands:
- Use negative prompts: “bad hands, extra fingers, mutated hands”
- Try ControlNet with hand-specific models
- Generate at higher resolutions
- Use inpainting to fix specific issues
- Some newer models (DALL-E 3, Flux) handle hands better
