Artificial Analysis：Nano Banana 2.1 生成速度慢于前代，但同速模型中画质最高
Nano Banana 2.1 is slower than earlier Nano Banana models, but no faster model scores higher in quality
AI 导读
Artificial Analysis 的独立生成速度基准显示，Nano Banana 2.1 每张 1K 图像约需 16 秒，Nano Banana 2 为 8.3 秒，Nano Banana 2 Lite 为 3.1 秒。它是 AA-Image-T2I v2.0 前六名中最快的模型，排名高于它的每个模型耗时至少是它的 3.3 倍。
推荐理由
AI 评分 59
独立速度基准给出 Nano Banana 2.1 与同系列及榜单前六的耗时对比，可据此判断画质与延迟的取舍。
