Nano Banana 2 - AI Image Generation & Editing at Flash Speed

The model (Gemini 3.1 Flash Image) is Google's latest state-of-the-art image generation and editing model, released on February 26, 2026. It combines the advanced world knowledge and quality of Nano Banana Pro with the lightning-fast speed of Gemini Flash, making Pro-level capabilities accessible to everyone.

The original Nano Banana used Gemini 2.0 Flash Experimental. The upgrade brings major improvements: subject consistency for up to 5 characters and 14 objects, precision text rendering and in-image translation, advanced world knowledge with web search grounding, production-ready specs from 512px to 4K, configurable thinking levels, and significantly improved visual fidelity with vibrant lighting and sharper details.

Gemini 3.1 Flash Image is Google's latest AI image model behind the platform. It delivers Pro-level image generation quality at Flash-level speed and cost. The model supports text-to-image generation, image-to-image editing, multi-image blending, and text rendering across multiple languages.

The model supports multiple resolution tiers: 512px for rapid iteration, 1K and 2K for standard use, and 4K for professional output. It also supports various aspect ratios including the newly added 4:1, 1:4, 8:1, and 1:8, plus standard ratios like 16:9, 9:16, 4:3, and 1:1.

The model maintains identity and appearance of up to 5 characters and fidelity of up to 14 objects across multiple generated images in a single workflow. This enables storyboarding, brand campaigns, and visual narratives without altering the appearance of your inputs — ideal for consistent content creation.

Configurable thinking levels let you control the model's reasoning depth. Minimal (default) is fastest for simple tasks. High or Dynamic thinking allows the model to reason through complex prompts before rendering, significantly improving output quality and prompt adherence for detailed creative work.

Yes. The model delivers precision text rendering — generating sharp, legible text for posters, marketing mockups, greeting cards, and diagrams. It also supports in-image localization, translating and rendering text in multiple languages directly within the generated image.

Available across Google products including the Gemini app, Search (AI Mode and Lens), Google AI Studio, Gemini API, Vertex AI, Google Antigravity, Firebase, and Flow. Our platform provides access through an easy-to-use interface powered by the same underlying model.

Absolutely. Production-ready specs, 4K resolution, subject consistency, and precise instruction following make it ideal for marketing content, social media assets, product visualization, and brand storytelling. All outputs include SynthID watermarking and C2PA Content Credentials for responsible AI provenance.

For best results: 1) Use detailed prompts and leverage enhanced instruction following, 2) Enable High thinking for complex creative requests, 3) Use subject consistency for series and campaigns, 4) Choose appropriate resolution and aspect ratio for your platform, 5) Experiment with image blending for creative compositions, 6) Use in-image localization for multilingual content.
