Your request will cost $0.15 per image. For $1.00, you can generate 6 standard images. 4K outputs will be charged at double the standard rate. If web search is used, an additional $0.015 will be charged. Note: Pricing may change in the future.
Google's Gemini 3 Pro Image architecture delivers production-quality visuals at $0.15 per image—understanding context like a multimodal foundation model, not keyword matching like traditional diffusion systems. Trading raw speed for sophisticated semantic interpretation and enhanced reasoning capabilities, it transforms complex creative direction into accurate visuals without prompt engineering gymnastics, making it ideal for teams that need studio-quality results with advanced text rendering and character consistency.
Built for: Marketing campaign generation | Product visualization workflows | Creative content production requiring text accuracy | Infographic and diagram creation at scale
Built on Google's Gemini 3 Pro foundation, Nano Banana Pro processes prompts through the same multimodal architecture that powers conversational AI understanding nuance, context, and creative intent rather than simple keyword matching. Where traditional diffusion models treat prompts as collections of weighted tokens, this approach interprets your creative direction holistically, capturing relationships between concepts that single-modality systems miss.
What this means for you:
Google's multimodal foundation prioritizes quality and reasoning depth over raw speed, optimized for production workflows requiring sophisticated outputs.

vs. FLUX.1 [dev]: Nano Banana Pro achieves semantic-aware generation with industry-leading text rendering through Gemini 3 Pro's multimodal reasoning, making it ideal for marketing materials requiring accurate typography. FLUX.1 [dev] prioritizes maximum resolution control and fine detail preservation for technical illustration workflows.
vs. Stable Diffusion 3.5: Nano Banana Pro achieves natural language interpretation and real-world knowledge integration through Gemini architecture, making it ideal for teams creating infographics and data visualizations without prompt engineering expertise. Stable Diffusion 3.5 prioritizes open-source flexibility for custom fine-tuning and on-premise deployment scenarios.
vs. Original Nano Banana (Gemini 2.5 Flash Image): Nano Banana Pro trades speed for quality, offering enhanced reasoning, superior text rendering, better character consistency, and advanced composition capabilities. Original Nano Banana remains available for rapid iterations and simple edits at lower cost ($0.039/image).
