Overview
- The Gemini 3.1 Flash Image model combines Gemini Flash speed with Pro‑level reasoning to generate and edit visuals in seconds at up to 4K resolution.
- Google highlights multi‑subject consistency by maintaining the likeness of up to five characters and the fidelity of up to 14 objects with improved lighting, textures, instruction following, and multi‑aspect outputs from 512 px to 4K.
- The system renders legible text inside images and supports direct translation and localization within the visual composition for uses such as marketing comps and data visuals.
- Availability spans the Gemini app, Google Search with AI Mode and Lens, AI Studio and the Gemini API, Vertex AI in Google Cloud, Flow as the default image model, and Google Ads, with Nano Banana 2 replacing Nano Banana Pro in standard Gemini menus as Pro access remains for AI Pro and Ultra subscribers and expansion reaches 141 additional countries and eight languages.
- Provenance measures include SynthID watermarking already used over 20 million times since November with C2PA content credentials coming to the app, while community analyses report roughly 4–6 second generations and potential 30–50% lower costs versus Nano Banana Pro.
