目前要直接访问谷歌官方渠道比较麻烦，可以使用以下网站来生成
1、访问下面网站
点击“Generate lmages”生成图片按钮
2、点击“Upload lmage”上传要生成手办的照片，最好是全身照（双人照识别效果欠佳，很难识别成功，官网生成也很随机，有时能生成）。
3、输入提示词：
Using the nano-banana model, 4K high-definition quality
a 1/7 scale commercial figurine of the character in the picture was drawn, in a realistic style and in a real environment. The figurine was placed on a computer desk with a round transparent acrylic base with no text on it.
On the left side of the desk, a monitor screen vividly displays the ZBrush software interface, showing the 3D model of the same figure in a mid-sculpting phase
Background, on the right side of the desk: A BANDAI-style box packaging. The box is pristine and features high-quality print of the original character artwork on the front. The box is slightly angled to show its 3D form.
studio-quality lighting with soft shadows, extremely high detail, depth of field. The environment should feel like a collector's personal workspace
4、lmarena.ai会随机使用两个文生图模型来生成图片，可能并不会使用nano banana模型生成，所以我在提示词中增加了一句（Using the nano-banana model）来强调，如果对生成效果不满意，可以点击箭头所指按钮重新生成。
