Google's Nano Banana 2.1 image model halves prices

Nano Banana 2.1 replaces Nano Banana 2, which Google released in February 2026. Google says the new version improves visual quality, text rendering, character consistency across conversation turns, wide panoramas and infographics. It can process up to 14 reference images at once, keeping up to four characters and ten objects consistent, and connects to Google Search. It offers minimal, medium and high thinking levels that affect image quality, and runs at Flash-tier speed.

The price cut is notable because the previous Pro tier, Nano Banana Pro, costs considerably more at 13.40 cents per 1K image versus 3.36 cents for 2.1. While 2.1 sometimes beats Pro by a wide margin in benchmarks, the article notes that Nano Banana 2 also matched it in those tests, and that Pro often still produces noticeably better images in practice. In one side-by-side comparison, Pro's image looked more realistic and natural, particularly in colors and proportions, while 2.1 struggled with scale.

The outcome hinges on whether benchmark wins translate into real-world quality for users who need precise outputs. Google plans to shut down the previous model, gemini-3.1-flash-image, on October 29, 2026, and has announced that the next major gain in image quality could come with its Pro model, Gemini 4 Argon.
