GoogleNano Banana 2 (Gemini 3.1 Flash Image) is Google DeepMind’s flagship Flash image model for high-fidelity generation and fast editing at scale, optimized for price and performance. It follows complex prompts more reliably and adds configurable thinking levels (Minimal vs High/Dynamic) to balance latency and quality. It improves text rendering in images, can generate or translate text across languages directly in the image, and uses world knowledge and web image search for more grounded, realistic output. It supports native aspect ratios (including 4:1, 1:4, 8:1, 1:8) and 512px/1K/2K/4K resolutions.
