Consejos

  • Prompt length: Nano Banana 2 supports up to 20,000 characters (vs 5,000 in Nano Banana), suitable for detailed descriptions.
  • Resolution: Choose 1K, 2K, or 4K for output resolution; parameter is case-insensitive (e.g. 2k or 2K both valid).
  • Aspect ratio: Full set includes 1:1, 1:4, 1:8, 3:2, 2:3, 3:4, 4:3, 4:5, 5:4, 8:1, 9:16, 16:9, 21:9, and auto. Some providers may not support all ratios; unsupported values are omitted for that provider.
  • Output format: Use png for lossless/transparency, or jpeg/jpg for smaller files (jpg is normalized to jpeg).
  • Image-to-image: Up to 14 reference image URLs when mode is image-to-image.
  • Callback mode: For high-concurrency scenarios, use callback mode to avoid frequent polling.
  • Image expiration: Result URLs are valid for 15 days. Download and store important outputs promptly.
  • Content moderation: Prompts must comply with content safety guidelines. Violations return CONTENT_VIOLATION.
  • google_search: Optional boolean; when supported by the provider, enables Google search for context. Default false.
Result URLs expire after 15 days. Download and store important outputs promptly. For high-concurrency scenarios, use callback mode to avoid frequent polling.
