题意：使用图像与@azure/openai进行交互或查询

问题背景：

On chat.openai.com I can upload an image and ask chatgpt a question about it, with the existing openai and @azure/openai api however there doesn't seem to be a way to do this? The ChatCompletion object in both cases only take text prompts.

在chat.openai.com上，我可以上传一张图片并就它向ChatGPT提问，但是使用现有的openai和@azure/openai API时，似乎没有办法做到这一点？在这两种情况下，ChatCompletion对象都只接受文本提示。

Is this feautre supported at an api level?

这个特性在API级别上得到支持吗？

问题解决：

With OpenAI you just include your image as part of the message that you supply. Here is a piece from the code I use, which works whether you have an image or not:

在使用OpenAI时，你只需要将你的图像作为你提供消息的一部分包含进来。下面是我使用的一段代码，无论你是否有图像，它都能正常工作。

if image != '':
    # Get base64 string
    base64_image = encode_image(image)
    content = [
        {
            "type": "text",
            "text": your_prompt
        },
        {
            "type": "image_url",
            "image_url": {
                "url": f"data:image/jpeg;base64,{base64_image}"
            }
        }
    ]
else:
    content = your_prompt
messages.append({"role": "user", "content": content})

And then        然后

payload = {
    "model": model_name,
    "temperature": temperature,
    "max_tokens": tokens,
    "messages": messages
}

where encode_image() is defined:        encode_image() 函数是在哪里定义的？

def encode_image(image_path):
    with open(image_path, "rb") as image_file:
        return base64.b64encode(image_file.read()).decode('utf-8')

Currently you need to target OpenAI model gpt-4-vision-preview. Update: As @Michael suggests, it also works with gpt-4o.

目前你需要将目标设定为OpenAI的模型gpt-4-vision-preview。更新：如@Michael所建议的，它也适用于gpt-4o
