If you want to use the **Google AI Studio API native request format**, please refer to the separate Gemini native image generation document instead of this file. --- ## Endpoint Use `POST /v1/images/generations` as the unified endpoint. This is a synchronous API. Upon successful request, image results are returned directly without polling. --- ## Authentication Use `Authorization: Bearer <CCAPI Token>`. --- ## Response Characteristics - Response structure follows the OpenAI Images style - The platform returns image URLs by default - The platform normalizes and hosts image results uniformly, without exposing underlying provider details --- ## Supported Models | Model Name | Capability Mapping | Resolution Tier | Description | |---|---|---|---| | `nano-banana` | Gemini 2.5 Flash Image | 1K | Basic | | `nano-banana-pro-1k` | Gemini 3 Pro Image Preview | 1K | Pro | | `nano-banana-pro-2k` | Gemini 3 Pro Image Preview | 2K | Pro | | `nano-banana-pro-4k` | Gemini 3 Pro Image Preview | 4K | Pro | | `nano-banana-2-0.5k` | Gemini 3.1 Flash Image Preview | 0.5K | Gen 2 | | `nano-banana-2-1k` | Gemini 3.1 Flash Image Preview | 1K | Gen 2 | | `nano-banana-2-2k` | Gemini 3.1 Flash Image Preview | 2K | Gen 2 | | `nano-banana-2-4k` | Gemini 3.1 Flash Image Preview | 4K | Gen 2 | The resolution is already encoded in the public model name, e.g. `nano-banana-pro-2k`, `nano-banana-2-4k`. --- ## Request Format Uses the OpenAI Images-compatible format: - `model`: Use the platform's public model name - `prompt`: Text-to-image prompt - `image`: Optional, supports single or multiple reference image inputs for image-to-image and multi-image blending - `aspect_ratio`: Optional, passed as a top-level field --- ## Aspect Ratio Support ### `nano-banana` / `nano-banana-pro-*` Supported: `1:1`, `2:3`, `3:2`, `3:4`, `4:3`, `4:5`, `5:4`, `9:16`, `16:9`, `21:9` ### `nano-banana-2-*` In addition to the above ratios, also supports: `1:4`, `4:1`, `1:8`, `8:1` --- --- ## Pricing Visit the [Pricing page](/pricing?vendor=Google) to see full model pricing for this provider.
