Nano Banana 2 AI Image Generator

Nano Banana 2 is a Gemini 3.1 Flash Image model optimized for fast, controllable image generation. On RightAI, use 1K to explore ideas quickly, 2K for most deliverables, and 4K when you need extra crispness for hero assets. It’s designed for predictable iteration: keep the same prompt structure, then scale up quality when you’re ready.

It supports both text-to-image and image-to-image. A common workflow is to generate a few directions from text, pick one, then refine with image-to-image using references. Nano Banana 2 accepts up to 14 reference images, which helps with brand packs, multi-character scenes, and product variations. Use references intentionally: one for identity, one for lighting, one for palette, and the rest for layout cues.

Instruction following is stronger when prompts read like a short creative brief. Call out fixed elements (“keep the logo and product shape unchanged”) and variable elements (“switch background to a minimal studio gradient”). Add layout constraints (“leave negative space for headline text”). For text-in-image, keep copy short and specify language plus formatting (alignment, casing, font style) to improve readability.

Resolution-based credits make cost control simple. Iterate at 1K or 2K until composition and edits look right, then re-run the best prompt at 4K for final output. Export JPG for typical web assets, and PNG when you need cleaner edges or plan to post-process.
