Nano Banana Pro

POST /v1/images/generations

​

What This Page Covers

• This page only covers nano-banana-pro
• The customer-facing entry point is POST /v1/images/generations
• The input image field is image_input
• The default public contract remains URL-based image_input; designated gray accounts also support data URLs, raw Base64, and three-image multipart editing
• Gemini / Vertex and other providers may sit behind this route, but those provider details are not part of the customer contract

​

Capability Status

​

Currently Validated Capabilities

• official Vertex channel 318 (vertexsophie) direct truth:
  • 2 reference images work
• local relay on localhost:4000, pinned to channel 318, verified:
  • single WEBP URL reference works
  • single JPEG URL reference works
  • 2 PNG URL references work
  • resolution: "1K" works
  • resolution: "4K" works
  • aspect_ratio: "1:1" works
  • aspect_ratio: "21:9" works
  • output_format: "png" works
  • output_format: "jpg" works
  • the response returns data[].url

• whether the exact multi-image limit is 8 or higher
• 2K
• exact large-file URL limit
• exact 30 MiB boundary
• additional aspect_ratio combinations
• exact output_compression semantics

​

Request Parameters

​

Current Multi-Image Status

• 2 references: verified
• gray user 11257 with three references: verified
• higher counts: exact upstream max is still pending, so do not promise it publicly yet

​

Routing Note

• single-image requests can use normal available carriers
• multi-image requests normally use official Gemini / Vertex carriers; designated gray accounts may use an explicitly verified gray carrier
• that is a server-side routing rule; the customer contract stays the same
