Nano Banana 2 adds search, 4K

Google is pushing image generation beyond prompt-only art bots and toward a search-grounded, production-ready multimodal API. The interesting part is not just prettier outputs — it is that developers can now combine live web context, conversational edits, and higher-resolution rendering in one cheaper Flash-tier model.

• –Search grounding now pulls in both text and image results, which should make visual generation and editing workflows more useful for real-world assets instead of purely synthetic scenes
• –New 0.5K, 2K, and 4K output options make the model more viable for marketing, design, and content pipelines that previously needed a second upscale step
• –Support for extreme aspect ratios like 1:8 and 8:1 broadens the model’s usefulness for banners, mobile creatives, and other awkward production formats
• –Google is explicitly framing it as the high-efficiency counterpart to Gemini 3 Pro Image, which suggests a two-tier strategy of premium quality versus fast, high-volume deployment
• –Early third-party coverage quickly treated it as a serious top-tier image model, so this looks less like a minor refresh and more like Google tightening its grip on API-first image generation
