Nano Banana 2.1 (Google)

Google's Nano Banana 2.1 is the successor to Nano Banana 2 — Flash-level speed with sharper visual quality, cleaner typography and more consistent multi-turn edits. Outputs 1K, 2K or 4K in 14 aspect ratios including 1:4, 4:1, 1:8 and 8:1 panoramas, fuses up to 14 reference images, and can ground on Google web and image search for real-time subjects. Pick a reasoning level to trade speed for fidelity. Provide images to edit them, or leave them empty for text-to-image.
