Google Nano Banana Pro API
Nano Banana Pro (Gemini 3 Pro Image) is Google's premium image generation model available via the Gemini API and Google AI Studio. It can generate and edit images at up to 4K resolution, blend up to 14 reference photos into a cohesive scene, and render text inside images with high accuracy. Access is available through both the Gemini API for developers and Vertex AI for enterprise scale. For agent builders already using Gemini models, this provides native multimodal generation in a single API ecosystem.
Viable option — review the tradeoffs
You need to generate high-fidelity images with accurate text rendering, real-world facts, and multi-image blending for dynamic agent visuals like infographics or mockups.
Excellent text accuracy and factual visuals via search grounding, but outputs vary with prompt quality; consistent for pros but may need iteration for complex blends.
Your agents require production-scale image gen with enterprise controls and native integration into existing Gemini workflows.
Reliable at scale with predictable JSON responses, strong multilingual text; quirks include search tool opt-in needed for grounding.
Preview Model Status
Uses 'gemini-3-pro-image-preview' ID, indicating potential instability or changes in API behavior.
Search Grounding Opt-In
Real-time data requires explicit tools=[{"google_search": {}}] in requests; forget it and images lack current facts—always display grounding metadata.
Nano Banana Pro beats on instruction following, text rendering, and API integration; Midjourney wins on artistic flair.
Pick for factual, text-heavy, programmable agent images with Gemini ecosystem fit.
Pick Midjourney for pure creative/discord-driven art without coding.
