Google's Nano Banana 2 brings smarter Image Generation to Free users

Google is rolling out Nano Banana 2, officially Gemini 3.1 Flash Image, across the Gemini app and other Google AI products, bringing several features that were previously tied to Nano Banana Pro into its faster image model. That includes more accurate text rendering, translation, stronger instruction following, and the kind of world knowledge Google says can help with diagrams, infographics, and marketing-style visuals. 

Google is trying to narrow the gap between the fast version and the premium one so the default experience feels far more capable than before.

Google says Nano Banana 2 can keep up to five characters consistent and preserve the fidelity of up to 14 objects in a single workflow. It supports outputs from 512 pixels to 4K and is supposed to follow more complex prompts with less drift. With this Google is really trying to improve its reliability.

Nano Banana 2 is replacing Nano Banana Pro across Fast, Thinking, and Pro modes in Gemini, while also showing up in AI Mode, Lens, AI Studio, the Gemini API, and the rest of Google’s stack. As Google wants this model to sit underneath search, chat, editing, developer tools, and workflow products so that image generation starts to feel less like an event and more like a built-in layer.

As Nano Banana 2 is getting better at readable text, infographics, and polished marketing-style visuals, the outputs are no longer just creative experiments. They start to look like finished assets people might actually believe or use. And because of that Google is also leaning on provenance tools like SynthID (Google’s watermark for AI-generated content) and C2PA content credentials (record of how an image was made).

At the same time, Google is not pretending the premium tier is gone. Nano Banana Pro still stays in the picture for specialized tasks and for work that needs maximum factual accuracy. That distinction is Google clearly wants Nano Banana 2 to be the version most people use most of the time, but it is not claiming every job now belongs to the faster model. What it is really doing is raising the floor.
