6. Google Bets on Speed With Nano Banana 2 as AI Image Race Heats Up

Google has rolled out a new version of its flagship image-generation model, Nano Banana 2, as competition in generative AI intensifies across consumer apps, cloud platforms, and advertising tools.

The model, technically called Gemini 3.1 Flash Image, replaces Nano Banana Pro in most versions of the Gemini app and is positioned as a faster, more accessible option for image creation and editing.

Announcing the launch on X, Google CEO Sundar Pichai wrote: “Introducing Nano Banana 2, our best image model yet 🍌🍌. It uses Gemini’s understanding of the world and is powered by real-time information and images from web search. That means it can better reflect real-world conditions in high fidelity.”

Nano Banana 2 blends the speed of Google’s Gemini Flash models with capabilities previously limited to its higher-tier Pro offering. The company says the new version can generate photorealistic images quickly while handling more complex instructions, multiple characters, and detailed object layouts.

Among the key upgrades:

• Stronger instruction following, aimed at reducing mismatches between prompts and outputs
• Subject consistency, allowing users to maintain resemblance across up to five characters and as many as 14 objects within a workflow
• Flexible production specs, with outputs ranging from 512px to 4K resolution
• Improved text rendering and translation, designed for marketing mockups and localized visuals

The model also draws from Gemini’s broader knowledge base and can use real-time, web-grounded information in certain contexts, enabling tasks such as generating infographics or converting notes into diagrams.

The emphasis on speed is strategic. Rivals, including OpenAI and Midjourney, have steadily improved generation quality while cutting latency. Adobe, meanwhile, continues to integrate Firefly more deeply into Creative Cloud, targeting professional designers with workflow-centric features rather than raw generation speed.

Unlike standalone image startups, Google’s advantage lies in distribution. Nano Banana 2 is being embedded across:

• The Gemini app (where it replaces Pro in Fast, Thinking and Pro modes, though Pro remains accessible for specialized tasks)
• Google Search, including AI Mode and Lens
• AI Studio and the Gemini API, in preview
• Vertex AI on Google Cloud
• Google Ads, where it powers creative suggestions during campaign setup
• Flow, Google’s lightweight creation environment

By weaving image generation into Search, Ads, and Cloud products, Google is tightening the link between generative AI and monetization, particularly in advertising, where creative asset production is a bottleneck.

Competitors are making similar moves. OpenAI has been pushing multimodal capabilities into ChatGPT for enterprise users, while Adobe has focused on commercially safe image generation and rights-protected datasets. 

Midjourney, meanwhile, remains largely platform-centric but is experimenting with more consistent character and scene generation, a feature Google is now explicitly highlighting.

Alongside model upgrades, Google is expanding its AI content labeling infrastructure. The company says it is combining its SynthID watermarking system with C2PA Content Credentials standards to improve verification of AI-generated media.

According to Google, the SynthID verification tool inside the Gemini app has been used more than 20 million times since launch in November to identify AI-generated images, audio, and video. C2PA-based verification is expected to roll out within the app soon.
