Integration Guidance

Start with the async image generation page when the selected model uses a polling flow. Kling uses /v1/images/tasks with operation for text generation, editing, multi-image reference, outpainting, and subject completion. For seedream-5.0-pro, use /v1/images/generations for text-to-image requests and /v1/images/edits for reference-image requests.

Nano Banana 2.1 uses synchronous endpoints rather than asynchronous tasks: use the generation/edit endpoints for OpenAI style or /v1beta/models/gemini-nano-banana-2.1:generateContent for Gemini style. Choose one request format from the dedicated pages above.

GPT Image 2.6 uses the synchronous Images API: /v1/images/generations for text-to-image and GIF, and /v1/images/edits for reference editing. Flare and Sunburst use their exact model IDs and share the same parameters.
