About Google Imagen (Gemini Image)

Google Imagen is Google’s image-generation model line, now layered with Gemini 3 Pro Image (codenamed Nano Banana Pro) for professional asset production with a ‘thinking’ composition step that refines layouts before generating. It pulls real-world grounding from Google Search and reaches 4K resolution. Imagen 4 ships Fast ($0.02/image), Standard ($0.04), Ultra ($0.06); Gemini 3.1 Flash Image runs $0.045–$0.151/image depending on resolution. Available via the Gemini API, Vertex AI, and bundled into Google Workspace plans.
