Gemini Nano Banana 2.1 is Google’s image generation and editing model, and the successor to Nano Banana 2. It is built to balance price and performance. Give it a prompt and up to 14 reference images, and it returns a finished image at up to 4K.
If Nano Banana 2 is already the default in your graph, Gemini Nano Banana 2.1 drops into the same slot. The resolution tiers carry over, the aspect ratio list gains 9:21, and each run costs less.
- Three thinking levels. Minimal, Medium and High. Use Minimal to explore quickly, High for dense layouts and prompts that stack several constraints, and Medium when you want something in between. Higher levels take longer and use more tokens.
