- Google Gemini 3.1 Flash 圖像生成模型(Nano banana2)
- 通過 model 參數選擇
gemini-3.1-flash-image-preview模型 - 支持文生圖、圖生圖,最高 4K 分辨率輸出
- 最多 14 張參考圖,保持風格/角色一致性
- 支持極端寬高比(1:4、4:1、1:8、8:1)
- 集成 Google Search 搜索增強,生成更貼合真實世界的圖片
- 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
