Automatically Passthrough Binary Images in OpenAI Assistant node?

Questions

Describe the problem/error/question

I’m trying to pass images to the openAI assistant like I did using “automatically pass through binary images” in the “AI Agent” node.

However, I don’t see the option on the Open AI’s “Message an Assistant” node.

Any plans for adding such feature?
or is there a way I can work around?
or is there a reason why this cannot be done?

It looks like your topic is missing some important information. Could you provide the following if applicable.

  • n8n version:
  • Database (default: SQLite):
  • n8n EXECUTIONS_PROCESS setting (default: own, main):
  • Running n8n via (Docker, npm, n8n cloud, desktop app):
  • Operating system:

Hey @Dae_Lee
Great question and I was curious to see how easy this would be to implement.

I discovered that assistant messages do not support base64 values like the chat completion APIs we’re used to in other AI nodes. Instead, to send an image to an Assistant, you are required to upload via the Files API and then reference the IDs when you send the message.

Here’s a possible workaround until this feature is supported in n8n.
