Best Practices

  • Detailed, specific prompts work best – the model understands compositional rules well
  • For text in images, specify the exact text you want rendered
  • You can specify colors using hex codes for precise brand matching
  • 1024×1024 resolution recommended

Limitations

  • Text rendered in images may be inaccurate or distorted
  • The model is not intended to provide factual information
  • May reflect biases present in training data
  • Output quality is influenced by prompting style
