Google's Nano Banana 2.1: Half Price, Sharper Images

Google cut the price of generating an image with Nano Banana in half and made the pictures sharper in the process. The company released Nano Banana 2.1 this week, replacing Nano Banana 2, which had only been out since February 2026. A 1K image now costs 3.36 cents, down from 6.70 cents, and a 4K image runs 7.56 cents instead of 15.10. That's a steep discount next to Nano Banana Pro, which still charges 13.40 cents per 1K image.

The cheaper price doesn't mean a weaker model. Google says 2.1 improves "across the board" on text rendering, character consistency, panoramas, and infographic generation, and it can now juggle up to 14 reference images while keeping four characters and ten objects visually consistent across a conversation. It runs on Gemini 3.6 Flash rather than the Pro-tier 3.1 model that powers Nano Banana Pro, which Google calls 2.1's "more efficient counterpart." The model also taps into Google Search and lets users pick between minimal, medium, and high thinking levels depending on how much quality they need.

Where this leaves the gap between the Flash and Pro tiers, and whether 2.1 can actually challenge Pro's output in practice, is where things get interesting.
