Vendor: Google Model ID: nano-banana-pro Capability: 2048² · photorealism · extended detail pass · material accuracy Pricing: per image, pro photoreal tier (live rate) Nano Banana Pro adds an extended detail pass and material-refinement step to the base Nano Banana renderer. The result is sharper texture work, cleaner highlights on glass and metal, and better skin / fabric rendering at hero-image scales. The latency cost is real (~2× base Nano Banana); reach for Pro when the image is the deliverable, not when you’re iterating.

When to use

  • Hero / campaign imagery where detail at print scale matters.
  • Product photography where material rendering is the brief.
  • For iteration / lower fidelity, see Nano Banana.
  • For better text rendering inside the image, see Nano Banana 2.
  • For 2048² aesthetic / illustration, see Seedream V4.5.
