Google: Nano Banana 2.1 (Gemini Nano Banana 2.1) · fastrouter
Google's gemini-nano-banana-2.1 (Nano Banana 2.1) is the successor to Nano Banana 2 (Gemini 3.1 Flash Image), built on Gemini 3.6 Flash for high-efficiency image generation and conversational editing at Flash-level speed and cost. It improves visual quality, text rendering, infographic layout accuracy, and multi-turn character consistency across 1K, 2K, and 4K output, fixes tiling artifacts on wide and panoramic aspect ratios, supports up to 14 reference images (up to 4 characters and 10 objects), grounding with Google Web and Image Search, and configurable thinking levels (minimal, medium, high). All outputs carry a SynthID watermark.
