Nano Banana 2 AI Image Generator

Nano Banana 2 is Google DeepMind's latest AI image generation model, officially designated Gemini 3.1 Flash Image. Released on February 26, 2026, Nano Banana 2 combines the professional-grade quality of Nano Banana Pro with the blazing speed of Gemini Flash. It generates high-fidelity images in 4-6 seconds and supports resolutions from 512px up to 4K, making it suitable for everything from social media posts to print-ready marketing materials.

Nano Banana 2 is approximately 4 times faster and 50% cheaper per image than Nano Banana Pro. While Nano Banana Pro remains the choice for maximum creative control and heavy art direction, Nano Banana 2 delivers Pro-level quality at Flash speed — ideal for high-volume workflows, rapid iteration, and batch processing. Nano Banana 2 also introduces new aspect ratios (1:4, 4:1, 1:8, 8:1) and 4K resolution support that Nano Banana Pro lacks.

Nano Banana 2 supports four resolution tiers: 512px (fastest, 3-8 seconds), 1K (default, 5-15 seconds), 2K (high quality, 10-25 seconds), and 4K (ultra-high definition, 15-40 seconds). The 4K option is exclusive to Nano Banana 2 and produces images at 4096×4096 pixels — suitable for large-format printing and professional production.

Nano Banana 2 generates images in approximately 4-6 seconds at 1K resolution — roughly 4 times faster than Nano Banana Pro. At 512px resolution, generation can be as fast as 3 seconds. This speed advantage makes Nano Banana 2 ideal for real-time creative iteration and batch processing workflows where every second counts.

Yes, text rendering is one of Nano Banana 2's standout capabilities. The model achieves 94.3% accuracy for in-image text generation, supporting both Latin scripts (English, Spanish, French, etc.) and CJK characters (Chinese, Japanese, Korean). This makes Nano Banana 2 excellent for creating marketing mockups, greeting cards, social media graphics, and product packaging with legible, properly formatted text.

Nano Banana 2 supports up to 14 reference images for style transfer, composite editing, and subject-aware transformations. Upload your reference images along with a text prompt describing the desired changes, and Nano Banana 2 will intelligently analyze and apply the edits while preserving the original composition and style.

Nano Banana 2 supports 14 aspect ratios: 1:1, 2:3, 3:2, 3:4, 4:3, 4:5, 5:4, 9:16, 16:9, 21:9, plus four new ratios exclusive to Nano Banana 2: 1:4, 4:1, 1:8, and 8:1. When editing existing images, you can also use 'match_input_image' to automatically match the aspect ratio of your uploaded reference image.

On ImageFX, Nano Banana 2 costs 6 credits per image at 512px or 1K resolution, 10 credits at 2K, and 16 credits at 4K resolution. Image editing operations with reference images cost the same credits based on output resolution. New users receive free credits upon signing up.
