Using Nano Banana 2 Inside Runnit Boards
One of the most effective ways to use Nano Banana 2 on RunDiffusion is within Runnit Boards. Boards allow you to organize prompts, reference images, outputs, and revisions into a structured workspace.
Instead of generating one-off images, you can:
- Store reference images directly on a Board
- Save prompt variations for comparison
- Maintain subject consistency across revisions
- Refine outputs in stages using multiple tools
- Compare iterations side by side
To add Nano Banana 2 to an existing Board:
Login to RunDiffusion Once you login you will be forwarded to the RunDiffusion Runnit Platform.
Click on the Runnit Boards on the left Sidebar
Open an existing Board or create a new board.
Click Add Tool and select Nano Banana 2.
Click the Image Kit.
Boards are particularly useful for multi-scene projects, architectural revisions, campaign testing, and client presentations where organization and repeatability matter.

Using Nano Banana 2 as a Single Use Tool
Nano Banana 2 can also be used by itself outside of a Runnit Board if you aren't in the need of a workflow but just need a fast render or editing tool inside RunDiffusion. This approach is ideal when you need a fast result without organizing a larger project workspace.
Instead of building a structured Board, you can simply click on the Try Nano Banana 2 which will bring you right to the tool.
- Generate one-off concept visuals
- Edit a single image quickly
- Test prompt variations rapidly
- Produce standalone marketing or presentation assets
Because Nano Banana 2 is powered by Gemini 3.1 Flash Image, you still benefit from:
- Strong instruction following
- High-resolution output up to 4K
- Subject consistency
- Fast iteration speed
The single-use approach keeps things simple and efficient while still delivering professional-quality results.
