Nano Banana 2.1 lowers image-output costs
Google released Nano Banana 2.1 on October 6, 2026, with the API model ID gemini-nano-banana-2.1. Google describes improvements to visual quality, text rendering, and character consistency across edits. Output supports 1K, 2K, and 4K; the 0.5K option from Nano Banana 2 is absent.
Using the published standard rows, 100 images at 2K cost $5.04 on Nano Banana 2.1, $10.10 on Nano Banana 2, and $13.40 on Pro for image output. Quality differences are not measured here. Nano Banana 2.1 has higher input and text/thinking rates than Nano Banana 2, so the image-output savings do not describe every request's total bill.
