Nano Banana 2 Lite
Nano Banana 2 Lite is a stable API for efficient image creation and local edits.
What the release provides
The model is optimized for 1K output and simple conversational changes. Google does not position it for complex multi-reference or long editing chains. Output carries SynthID and C2PA provenance.Nano Banana 2 Lite official API documentation
How to use it well
Practical guidance. Break an editing task into a clearly defined local change and a fixed reference image. If the task depends on several characters or detailed continuity across many turns, compare another image model on those exact requirements before adopting this one.
