Gemini 3.1 🍌

Nano Banana 2 (Gemini 3.1 Flash Image) is Google's latest image generation and editing model, combining Pro-level capabilities with Flash-tier speed. Built on the Gemini 3.1 Flash Image architecture, it brings advanced world knowledge, deep multimodal reasoning, and subject consistency to both text-to-image generation and image editing workflows, delivering production-ready results in seconds rather than minutes.

What sets Nano Banana 2 apart is its semantic understanding of editing instructions. Instead of requiring masks, layers, or region coordinates, you describe what you want changed in plain language, and the model reasons about which elements to modify while leaving the rest intact. Supply up to 14 reference images in a single request for compositing, style matching, subject transfer, or multi-scene assembly — the model simultaneously understands relationships across all inputs, maintaining coherence in composition, lighting, and style throughout the edit.

Nano Banana 2 is built for fast, iterative creative workflows: product photo retouching and variation, style transfer and creative remixing, multi-image compositing, and design iteration requiring quick turnaround. Outputs carry rich color and punchy contrast with SynthID digital watermarking on all generated images. Optionally ground generations in real-time web information via the for prompts that benefit from current knowledge.

How It Compares

vs. Nano Banana Pro Edit (Gemini 3.0 Pro Image)

Gemini 3.0 Pro 🍌

Nano Banana Pro prioritizes maximum reasoning depth for complex, multi-step edits that require precise compositional control — at a higher cost and with slower throughput. Nano Banana 2 trades some of that depth for significantly faster inference and lower cost, making it the right choice for iterative workflows, rapid prototyping, and production pipelines where turnaround time matters. For straightforward edits and style transfers, Nano Banana 2 will match or exceed Pro quality at a fraction of the cost.

vs. FLUX.2 [dev] Image-to-Image

FLUX 2 (Dev)

FLUX.2 [dev] offers strength-based image-to-image with fine-grained control over how much of the original image to preserve, making it well-suited for diffusion-style transformations where you want to dial in the blend between source and output. Nano Banana 2 takes a different approach — semantic rather than strength-based — accepting up to 14 reference images and understanding editing instructions through Gemini's multimodal reasoning. Choose FLUX.2 when you need precise control over preservation strength; choose Nano Banana 2 when you want to describe the edit in natural language and let the model reason about what to change.
