ratio	string	是	图片比例
model	string	否	模型选择

model 选项

• jimeng-image-4.5 - 最新模型 (高质量)
• jimeng-image-4.1 - 4.1 模型
• jimeng-image-4.0 - 4.0 模型
• jimeng-image-3.1 - 3.1 模型 (艺术风格)
• jimeng-image-3.0 - 3.0 模型 (默认)

比例选项

21:9, 16:9, 3:2, 4:3, 1:1, 3:4, 2:3, 9:16

默认行为

• 每次生成会返回 4张 图片变体（item_list数组）
• 4.x 模型使用 2K 分辨率
• 3.x 模型使用 1K 分辨率

重要提示

• 即梦每次生成会返回4张不同变体的图片
• 查询结果时需要遍历 item_list 数组获取所有图片
• 每张图片的URL在 item_list[i].image.large_images[0].image_url
