中國大陸用戶請注意: 中國大陸用戶請使用
https://toapis.cn 作為接口地址(Base URL)。文檔示例中的 https://toapis.com 請替換為 https://toapis.cn。- 直連 Google Vertex AI,使用 Gemini 3.1 Flash Image 原生 API
- 通過 model 參數選擇
gemini-3.1-flash-image-official模型 - Nano Banana 2 aliases:
nano-banana-2-lite-officialandnano-banana-2-official - 支持文生圖、圖生圖
- 支持 temperature、topP、maxOutputTokens 等原生生成參數
- 支持 resolution(1K/2K/4K)、personGeneration、imageOutputOptions 圖像配置
- 支持 thinkingConfig 思考模式,提升複雜場景生成質量
- 支持 safetySettings 安全設置
- 支持極端寬高比(4:1、8:1)
- 異步任務管理,通過任務 ID 查詢結果
重要變更:爲了更好的性能和成本控制,我們不再支持在
image_urls 中直接傳入 base64 圖片數據。請先使用 上傳圖片接口 上傳圖片,獲取 URL 後再調用本接口。Authorizations
