Google (NASDAQ:GOOGL) on the day of the announcement introduced Nano Banana 2, the latest iteration of its image-generation technology, marketed internally as Gemini 3.1 Flash Image. The company says the model brings several capabilities that had been limited to its Pro offering into a faster, more broadly available model.
Among the features carried over from the Pro tier are enhanced world knowledge integration, more accurate rendering and translation of text within images, and the ability to upscale images from 512 pixels to 4K resolution. The firm describes Nano Banana 2 as able to preserve the likeness of up to five characters while maintaining fidelity for as many as 14 distinct objects in a single generation workflow.
Visual quality improvements are highlighted in Google’s description of the model, which includes more dynamic lighting, richer surface textures and increased sharpness. Users will also have additional control over aspect ratios and output resolutions. Nano Banana 2 draws on Gemini’s real-world knowledge base and is powered by real-time information and imagery accessible via web search.
The rollout starts today across a range of Google products. The company lists deployment in the Gemini app, Search, AI Studio, the Gemini API, Google Cloud’s Vertex AI, Flow and Ads. Within the Gemini app, Nano Banana 2 will supplant Nano Banana Pro across the Fast, Thinking and Pro performance tiers. Customers subscribed to Google AI Pro and Ultra plans will continue to have access to Nano Banana Pro for tasks that require that specialized capability set.
On provenance and verification, Google said it is continuing a dual approach by combining SynthID technology with C2PA Content Credentials. The company reports that the SynthID verification feature in the Gemini app has been used more than 20 million times across multiple languages since its November launch. Google added that C2PA verification will be integrated into the Gemini app in the near future.
Nano Banana first captured widespread attention after going viral in August of last year. A subsequent release, Nano Banana Pro, arrived in November. Google framed the viral success of the original Nano Banana as an influence on its efforts to remain competitive with OpenAI in developing broadly adopted AI services.
While the company has emphasized speed and extended Pro-level capabilities, some aspects of the rollout remain in transition - notably the phased introduction of C2PA verification and the continued availability of Nano Banana Pro for specific subscriber tiers. The broader product deployment across search, cloud and advertising platforms underscores the model’s intended reach across Google’s ecosystem.
