Google Nano Banana 2.1: Cheaper AI Image Generation

Google released Nano Banana 2.1, a new image generation and editing model built on Gemini 3.6 Flash. According to the company, the update improves visual quality, text rendering, and character consistency across conversation turns while reducing operational expenses.

How much do costs drop with Nano Banana 2.1?

Google cut pricing by roughly 50% compared to the previous version. A 1K image now costs 3.36 cents, down from 6.70 cents. For a 4K resolution image, the price drops from 15.10 to 7.56 cents. In comparison, the high-end Nano Banana Pro remains significantly more expensive at 13.40 cents per 1K image.

Does it replace the Pro model in daily workflows?

Although version 2.1 outperforms the Pro model in specific benchmarks like multi-character consistency, practical tests show that Nano Banana Pro still delivers superior natural colors and proportions. However, version 2.1 introduces support for up to 14 reference images simultaneously, keeping up to four characters and ten objects consistent.

The model runs at Flash-tier speed and is already rolling out across Google products, including Google AI Studio, Flow, and Ads. The older gemini-3.1-flash-image model will be shut down on October 29, 2026.
