Nano Banana 2.1 model workspace

Generate a new image or edit an existing visual with Nano Banana 2.1

Released by Google on October 6, 2026, Nano Banana 2.1 updates its high-efficiency image generation and editing model. It is selected by default here. Create from text, or upload one reference image and describe changes to the subject, background, material, lighting, composition, or visible text.

The workspace provides a prompt, one reference image, seven common aspect ratios, and 1K, 2K, or 4K output. Use 1K to test a direction, 2K for everyday content, or 4K when the final visual needs closer inspection. The Generate button shows the credit cost before submission.

For reference-image editing, separate changes from details that must remain stable. Preserve product geometry, identity, pose, and camera angle while replacing the environment, palette, or poster title. Clear constraints make revisions easier to evaluate.
