Tips

  • Generation time:
    • 2K resolution: ~25-35 seconds
    • 4K resolution: ~40-55 seconds
    • Submit task, wait 20 seconds, then poll every 3 seconds
  • Callback mode: For high-concurrency or high-resolution generation, use callback mode.
  • 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.
  • High resolution: Supports up to 4K output, ideal for high-quality printing and professional use.
  • Batch generation: max_images supports 1-10, generate multiple candidates at once, billed per image.
  • Sequential images:
    • disabled: Generate independent images, no relation
    • auto: Intelligently generate sequential images with continuity and coherence
    • Sequential mode is ideal for storyboards, comic panels, etc.
  • Multiple reference fusion:
    • image-to-image mode supports up to 14 reference images
    • Model intelligently combines style, composition, and color
    • More references = richer fusion effects
  • Resolution selection:
    • 2K: Balanced quality and speed, for most scenarios
    • 4K: Highest quality, for professional creation and printing
  • Aspect ratio suggestions:
    • 16:9 / 21:9: Landscape, for banners and desktop wallpapers
    • 9:16: Portrait, for mobile wallpapers and short video covers
    • 1:1: Square, for social media
  • Image formats: image_urls supports JPG, PNG, WebP, max 10MB per image.
Result URLs expire after 15 days. Download and store important outputs promptly. For high-concurrency scenarios, use callback mode to avoid frequent polling.
