# Gemini Nano Banana 2.1

**Gemini Nano Banana 2.1** (`gemini-nano-banana-2.1`) is the latest
high-efficiency image generation and conversational editing model. An update
to Nano Banana 2
([Gemini 3.1 Flash Image](/docs/models/gemini-3.1-flash-image)), it maintains
Flash-level speed and cost efficiency while delivering significant
improvements in visual quality, prompt adherence, multi-turn character
consistency, and text rendering. It serves as the more efficient counterpart to
[Gemini 3 Pro Image](/docs/models/gemini-3-pro-image) (Nano Banana Pro).

**Key updates:**

* Improved visual quality and realism across `1K`, `2K`, and `4K` output
  resolutions (default `1K`)
* Fixed tiling artifacts on wide and panoramic aspect ratios (`1:4`, `4:1`,
  `1:8`, `8:1`) at `2K` and `4K` resolutions
* Enhanced text rendering and infographic layout accuracy
* Multi-image fusion supporting up to 14 reference images (character consistency
  for up to 4 characters and object fidelity for up to 10 objects)
* Grounding with Google Web and Image Search
* Configurable Thinking levels (`minimal`, `medium` default, and `high`)
