Google releases Nano Banana 2.1 with 4K output, cheaper API pricing, and better Chinese text

Google has released Nano Banana 2.1, an image generation model that the article says improves visual design, mask-based editing, subject consistency, and natural-looking imagery.

It reports that the model ranks fourth in text-to-image on Arena, 80 points above its predecessor, and that API prices for 1K and 2K images were halved while 4K fell about 25%.

Testers note faster generation but weaker finish than GPT Image 2.5 and a watermark bug that degrades images over repeated edits.
