Our take
Written Aug 2, 2026Nano Banana Pro is Google's proprietary image-generation and editing model that accepts both text and images and returns both text and images. It offers a 65,536-token request limit and is available through two hosted endpoints with different throughput characteristics.
Choose this for image generation or editing tasks where you need text and image input alongside text and image output, or when your multimodal prompts need a 65-thousand-token request limit. Use the Google AI Studio endpoint if moderate throughput matters. Skip it if you need measured quality benchmarks to guide your choice, or if you want to self-host rather than use a hosted API.
The case for it
- Moderate throughput of 75 tokens per second available on the Google AI Studio endpoint.
- Text and image input with text and image output supports complex multimodal workflows.
The case against it
- Output costs six times the input cost, making image-heavy workloads expensive.
- No benchmark scores in our data, so there is no measured quality data.
- Throughput on the OpenRouter endpoint is unverified.
How good is it?
We hold no score for this model.
We look for every model we track on every board we watch, and none of them has turned up Nano Banana Pro (Gemini 3 Pro Image Preview) — so there is no intelligence, coding, agentic or writing score to show you, not a low one, none.
Or rent it from someone else
Why this differs from the header. The strip above quotes Google AI Studio's own list price. This is the cheapest live offer at the widest standard context we hold, whoever is serving it — a reseller undercutting a lab is ordinary commerce, not an error.
