GNano Banana 2 API
gemini-3.1-flash-image-preview-token
Nano Banana 2 API brings Google's Gemini 3.1 Flash Image route to APINEED for rapid text-to-image generation and conversational image editing. [1][2][3]
Google positions Nano Banana 2 as its versatile image workhorse, combining Flash-speed iteration with world knowledge, stronger text rendering, multi-reference consistency, and output up to 4K. APINEED exposes the verified non-streaming Chat Completions request and securely publishes local references through short-lived object-storage URLs. [1][2][3]

Benchmarks
Editorial benchmark data is shown when this model has a verified match.Intelligence uses the source’s median-score ranking. Efficiency views are APINEED calculations, not official LLM2014 rankings. Test costs and reference prices are converted at ¥7 per US dollar; they are not APINEED selling prices. Missing values are N/A. These results describe the source’s tested configurations, not guaranteed APINEED endpoint performance.

Nano Banana 2 API questions
Practical answers for selecting, integrating, pricing, and operating Nano Banana 2 API on APINEED.
What is Nano Banana 2 API best suited for?
It is suited to fast visual iteration, localized marketing graphics, reference-guided edits, product concepts, and images that need readable text. Google positions it as the general-purpose balance of quality, latency, and cost in the Nano Banana family. [1][2]
How does Nano Banana 2 differ from Nano Banana Pro?
Nano Banana 2 emphasizes Flash-speed iteration and price-performance. Nano Banana Pro is the premium route for the most complex production assets, deeper reasoning, and precision control. [1][2]
Which APINEED endpoint does Nano Banana 2 use?
Send gemini-3.1-flash-image-preview-token to POST /v1/chat/completions with stream set to false. This is not the standard Images API route. [3]
Can Nano Banana 2 use reference images?
Yes. The API contract accepts image_url content blocks containing an accessible URL or image data URL. The browser playground uploads local references directly to temporary private object storage before submitting those short-lived URLs. [2][3]
Why are size and aspect-ratio controls absent?
Google supports production image specifications in its native API, but APINEED does not currently guarantee those model-level fields on this Chat Completions adapter, so the page does not present controls that may be ignored. [2][3]
How does the APINEED page read the result?
It examines choices[0].message.content for Markdown image data URLs and raw data:image URLs. If no image is found, it preserves the response text and request ID instead of reporting a false success. [3]
