Gemini 3.1 Flash Image (Nano Banana 2)

Native 2K output, lightning-fast generation, and dramatically improved text rendering.

What Is Nano Banana 2 API?

Nano Banana 2 is an upgraded AI image model that produces realistic visuals, clear text elements, and smooth creative editing. It expands on the original Nano Banana technology with improved reasoning, higher resolution capabilities, and integrated text-to-image workflows.

Where It Fits in the Lineup

Nano Banana 2 is not a direct successor to Nano Banana Pro, it occupies a distinct product tier. While Pro targets professional workflows demanding maximum photorealism and fine detail, Nano Banana 2 is engineered for speed, volume, and cost-efficiency. In several spatial reasoning benchmarks it even outperforms the flagship Pro model.

Nano Banana proved the concept. Nano Banana Pro raised the quality ceiling for professionals who could accept slower speeds. Nano Banana 2 now bridges the gap, delivering Pro-level resolution at Flash-tier speed, positioning itself as the workhorse model for volume-driven use cases.

API Pricing

Input: $0.325 / 1M tokens

Output: $78.00 / 1M tokens

Key Features & Technical Capabilities

Improved Text Rendering

Legible, stable text inside AI-generated images has long been an unsolved challenge. Nano Banana 2 introduces a substantially upgraded text rendering engine with multilingual support. Posters, ad banners, social covers, and packaging mockups with typographic elements can now be generated cleanly  without manual retouching in Photoshop afterward.

High-Fidelity Style Transfer

Feed Nano Banana 2 a visual reference image and it accurately inherits the color palette, texture language, and compositional grammar of that reference across new generations. This makes it a powerful tool for brand-consistent content creation and artistic direction at scale.

Strong Spatial Logic

Multi-character scenes with physically plausible anatomy, accurate reflections, correct shadow casting, and realistic lighting behavior are areas where Nano Banana 2 notably outperforms expectations for a Flash-tier model — in some tests beating even Nano Banana Pro on spatial coherence.

Create From a Text Prompt

Image Generation is Nano Banana 2's primary mode: given a natural language prompt, the model synthesizes a brand-new image from scratch. There is no input image, the model constructs every pixel based entirely on its interpretation of the text description, sampling from its training distribution at native 2K resolution.

  • Zero input required — fully text-driven creation
  • Fastest throughput in the Nano Banana lineup
  • Supports multimodal prompts: text + style reference image
  • Aspect ratio control: square, portrait, landscape
  • Strong prompt-to-semantic fidelity across complex scenes

Transform an Existing Image

Image Editing takes an existing image as primary input and applies targeted, instruction-driven modifications. Rather than generating something new from nothing, the model parses the spatial structure, lighting, and semantic content of the provided image and makes precise, localized changes, while actively preserving the parts of the image that the user did not request to alter.

  • Requires source image + natural language instruction
  • Localized edits — non-targeted regions remain intact
  • Lighting, background, style, and object-level control
  • Maintains facial identity and perspective across iterations
  • Supports inpainting masks for surgical-precision changes

Who Should Use Nano Banana 2?

Marketing & Advertising

Social media managers, performance marketers, and e-commerce teams can generate large batches of ad creatives, UGC-style banners, and product visuals in minutes. The improved text rendering means typographic overlays are production-ready out of the box.

Design Prototyping

Product designers and UX teams benefit from the model's near-instant speed. Concept iteration that previously took hours can happen in seconds, keeping creative momentum without breaking flow for rendering delays.

Content Creators & Bloggers

Fast, high-resolution output with reliable text inside images makes Nano Banana 2 ideal for generating cover art, thumbnails, social stories, and editorial illustrations without needing a design background.

Video Frame Generation

Creating consistent keyframes for video AI tools like Kling 3.0 or Sora 2 is a natural fit. Nano Banana 2's character consistency features make it well-suited as an upstream tool in animation and short-form video pipelines.
