Allow to use a dynamic list as user/assistant prompts for chats in OpenAI

Feature Requests

The idea is:

Allow the Open AI node in chat mode to accept a dynamic list of user/assistant prompts.

My use case:

I have a dynamic list of messages that I have to enter in the Open AI Chat API (either GPT 3.5 or GPT 4). For example:

[
  { "role": "system", "content": "You are a helpful assistant." },
  { "role": "user", "content": "Who won the soccer world cup in 2018?" },
  {
    "role": "assistant",
    "content": "The 2018 FIFA World Cup was won by the French national football team."
  },
  { "role": "user", "content": "Where was it played?" }
]

The number of messages is not fixed, it may vary over time.

I think it would be beneficial to add this because:

It’s the way the Chat API work. You need to provide all the previous user/assistant messages.

I tried doing so with the provided input fields, but if the dynamic list doesn’t match the number of fields, it throws an error, so it’s not possible:

Any resources to support this?

I opened it as a question before doing the feature request: Use a dynamic list as prompts in OpenAI API

Are you willing to work on this?

No at this moment.

This is pretty essential for the OpenAI Chat endpoint as the message history (list) is what gives it the ability/context to reply to longer conversations with the user.

This is essential for many use cases. …If this means we can not define system messages as of now…

Hi, I come across this topic because I am doing a test migration to n8n but have exactly the same problem with dynamic histories. Is there any update to this or will I have to use a custom HTTP setup?

In my case there is a bunch of logic, eg. to “compress” the context in longer conversations.
