Photo Booth Upload offers several 'modes' of AI rendering: Gemini NB, Gemini NB2 and Gemini Pro. These each have their own strengths and weaknesses. While there is no specific formula to determine when to use one option over the other, we recommend starting with Nano-Banana. NOTE: Stable Diffusion has been deprecated and replaced with Gemini options given their speed and interpretive strengths


While Stable Diffusion is more literal (and slower), Gemini (NB/NB2) and Gemini (Pro) are more interpretive (and faster). 


Below is a rough break-down of the strengths and weaknesses of each, but you will always need to experiment with prompts regardless of which option you choose:




  • Use Stable Diffusion when (NOW DEPRECATED):
    • You want consistent, brand-aligned images
    • Prompts are pre-configured or professionally designed
    • Users expect high realism or tightly controlled style fidelity
  • Use Gemini Nano-Banana when:
    • Ease of use is critical
    • You want fast, playful generation with minimal prompt discipline
    • The experience is informal, experimental, or “let’s see what happens”
    • You need strong text rendering inside images (comic captions, stylized words like “POW”)
    • Video results: Good for short, playful clips with some randomness and surprise
  • Use Gemini Nano-Banana 2 when:
    • You want speed without losing composure (very fast, but not chaotic)
    • Prompts should feel natural and balanced, not overly strict or overly loose
    • You need high ease of use with better consistency than Nano-Banana
    • Visual output should stay more stable across iterations (fewer random style swings)
    • You care about brand-friendly results without going full “studio pipeline”
    • You’re building polished-but-lightweight experiences that don’t need heavyweight modeling
    • You want strong handling of complex prompts (multi-object scenes, relationships, layered descriptions)
    • You still want good text-in-image support, slightly more controlled than Nano-Banana
    • You want a sweet spot for fast, structured creativity rather than pure experimentation
    • Video results: Good for usable short branded clips, more polished than Nano-Banana
  • Use Gemini Pro when:
    • You want faster results than Stable Diffusion, but more coherence than Nano-Banana
    • Users expect smarter interpretation (poses, scenes, moods, relationships between objects)
    • You’re building semi-polished experiences that still need speed
    • You want higher resolution images (up to 4K)
    • You want generative prompt renders that can be something other than square (such as Landscape and Portrait)
    • Video results: Best for cinematic prompts, follows the story-board more directly with camere movement and structured scenes
