Problem uploading base64 img to assistant with Vision

[merry grove]

Hi, im trying to upload and image to an assistant in base64 but i got an invalid format error.
Code:

var message = await openai.beta.threads.messages.create(
            thread.id,
            {
                role: "user",
                content: [
                    {
                      "type": "image_url",
                      "image_url": {"url": "data:image/jpeg;base64,/9j/4AAQSkZJRgABAQAAAQABAAD/4gHYSU..."}
                    }
                ]
            }
        );

assistants dont support base64

[merry grove]

only chat completion supports base64??

[idle junco]

yes, for assistants its either external url or file id

Will they add base64 support for the assistants as well? I need to continuously upload images every 5 seconds, and having to do it through an external link or by uploading them to OpenAI and then getting the ID seems like a less optimized process

i dont know but i doubt it since large base64 strings saved in threads is far more non optimal. if you need such interval then why use assistants for it? chat endpoint is much faster and outputs can be added to threads
