GPT-image2.5 API 还是这么喜欢生成透明度图片哦知道有个参数可以关闭，我要去操作下：可以。GPT Image 2.5 API 可以关闭透明背景生成，只需要把 background 参数设置为 "opaque"。例如： ``` from openai import OpenAI client = OpenAI() result = client.images.generate( model="gpt-image-2.5-sunburst", prompt="一只坐在草地上的猫", size="1024x1024", quality="medium", background="opaque", # 强制非透明背景 output_format="png" ) ```
