Our take
Written Sep 2, 2026Nano Banana 2 Lite is Google's proprietary lightweight model for text-and-image tasks, with a 65,536-token request limit and consistent pricing across its three hosted offers. It is a fast, low-cost pick for image generation and editing where measured quality data is not yet available.
Pick this for low-cost image generation and editing, or fast prototyping via Google AI Studio at its highest measured speed. Use it for Vertex AI integration in enterprise workflows where the slower measured endpoint still suits your pipeline. Skip it if you need verified quality scores, or if throughput variation across endpoints risks your latency budget.
The case for it
- Same pricing on all three tracked providers, so provider choice is driven by speed and workflow rather than cost.
- Fastest on Google AI Studio at 465 tokens per second, well above its Vertex speed.
The case against it
- No benchmark scores in our data — chat, reasoning, coding and image quality are all unverified.
- A 203-token-per-second gap between the fastest and slowest measured endpoints, with the third undisclosed.
How good is it?
We hold no score for this model.
So there is no figure here for everyday use, coding, agent work or writing. That is a gap in our data, not a low score.

What each host's API supports
