How do I improve face quality?

If the model's face is blurry or distorted, please check the following.

1. Cause: Differences in model specifications and optimization

  • Nano Banana: It has limitations in precisely rendering facial features and skin texture. In particular, image quality degradation becomes more noticeable with repeated edits.

  • Flux 2 series (Pro/Max): This model is optimized for generating high-resolution photorealistic images. With billions of parameters, it delicately depicts a person’s eyes, eyelashes, and even skin pores.

2. Solution

2-1. Use an upscaler

26.04.29: Upscaler

2-2. Use the Flux 2 model + facial quality enhancement prompts

After switching the model to Flux 2 Pro or Max, try adding the following 'face detail-related keywords' to your prompt. The Flux 2 engine removes the AI-like feel when describing "skin texture" and the "depth of the eyes," and converts it to photorealistic image quality.
