Nano Banana 2 vs Nano Banana Pro

Gemini 3.1 Flash Image against Gemini 3 Pro Image — fast, panoramic-capable generation versus the highest compositional quality in the Nano Banana family.

Nano Banana 2 (Gemini 3.1 Flash Image) and Nano Banana Pro (Gemini 3 Pro Image) are the two newest models in the family. Nano Banana 2 is the Flash-tier option: faster, cheaper, with a unique 0.5K draft tier and 15 aspect ratios including ultra-wide panoramics. Nano Banana Pro is the Pro-tier option, tuned for maximum quality and reasoning.

Both render text well and keep up to five characters consistent. The decision usually comes down to speed and format flexibility (Nano Banana 2) versus top-end compositional quality and text precision (Nano Banana Pro).
