Model identity, supported workflow, and output guidance were checked against Google’s current model card and this site’s production configuration.
生成前先看已核验事实
以下信息来自当前产品配置与所链接的一手文档。实际输出质量仍会受提示词与输入图像影响。
- Google model ID
- Gemini 3.1 Flash Image
- Banananano route
- Kie.ai · nano-banana-2
- Input workflows
- Text + reference images
- Documented output
- 0.5K to 4K
Google identifies this efficient general-purpose image model as Nano Banana 2.
The generator uses the configured Kie.ai model route. Users do not provide a separate API key.
The current product configuration enables both text generation and reference-guided editing for this model.
Google’s model card documents 0.5K, 1K, 2K, and 4K. This interface currently presents the resolutions supported by its provider route.
快速探索图像方向
当你想快速探索一个概念，再把最好的结果推进到更高精度设置时，Nano Banana 2 很适合。
- 创意发散和情绪板
- 社媒概念图与缩略图
- 基于参考图的风格和构图变化
它在工作流中的位置
先用 Nano Banana 2 快速生成多个方向，再把表现好的提示词推进到 Pro 或专门模型中精修。
- 先生成多个视觉方向
- 保存表现最好的提示词片段
- 用模型对比页选择下一步模型
Test Nano Banana 2 without cherry-picking
A useful test asks whether the model completes your brief reliably—not whether one gallery image looks impressive.
- 1Define the output job and three non-negotiable requirements before generating.
- 2Run the same prompt at least three times with one fixed aspect ratio and resolution.
- 3Score prompt adherence, anatomy or geometry, text, and edit fidelity at full size.
- 4Only compare another model after keeping every controllable input the same.
This guide summarizes documented capabilities and a repeatable test method. It does not present invented latency, win-rate, or quality scores.
