Google, 오늘 Gemini에 출시될 Nano Banana 2 AI 이미지 모델 공개

The last year has been big for Google’s AI efforts. Its rapid-fire model releases have brought it to parity with the likes of OpenAI and Anthropic and, in some cases, pushed it into the lead. The Nano Banana image generator was emblematic of that trend when it debuted last year, and subsequent updates only made it better. Now, Google has announced yet another update to its image model with Nano Banana 2, which is available starting today. Nano Banana 2 is more accurately known as Gemini 3.1 Flash Image—the previous Nano Banana models were based on the 3.0 branch. According to Google, the new release can deliver results similar to Nano Banana Pro but with the speed of the non-pro Flash variant. Google promises the new image generator will have more advanced world knowledge pulled from the Internet by the Gemini 3.1 LLM. This apparently gives it the necessary information to render objects with greater fidelity and create more accurate infographics. The days of squiggly AI text were already ending, but Google says Nano Banana 2 has Pro-like text accuracy in image outputs. With Nano Banana 2, Google promises consistency for up to five characters at a time, along with accurate rendering of as many as 14 different objects per workflow. This, along with richer textures and “vibrant” lighting will aid in visual storytelling with Nano Banana 2. Google is also expanding the range of available aspect ratios and resolutions, from 512px square up to 4K widescreen. So what can you do with Nano Banana 2? Google has provided some example images with associated prompts. These are, of course, handpicked images, but Nano Banana has been a popular image model for good reason. This degree of improvement seems believable based on past iterations of Nano Banana. Google must be pretty confident in this model’s capabilities because it will be the only one available going forward. Starting now, Nano Banana 2 will replace both the standard and Pro variants of Nano Banana across the Gemini app, search, AI Studio, Vertex AI, and Flow. In the Gemini app and on the website, Nano Banana 2 will be the image generator for the Fast, Thinking, and Pro settings. It’s possible there will eventually be a Nano Banana 2 Pro—Google tends to release elements of new model families one at a time. For now, it’s all “Flash” Image.
