I’m looking to integrate an AI agent into my n8n workflow.
I’m considering using OpenAI’s GPT-3.5 Turbo and 4o.
Which subscription is more suitable for this use case: the API key subscription or the OpenAI Plus subscription? What factors should I consider when making my decision?
It looks like your topic is missing some important information. Could you provide the following if applicable.
Afaik there is only the ChatGPT Plus Subscription and the OpenAI API, the ChatGPT Plus Subscription only includes ChatGPT with the GUI, the API can only be accessed via the api key which gets priced by usage. You can only use the API with N8N.
Hello @Roxester ,
Welcome to the n8n Community forum.
Thanks for sharing your use-case and for the question.
I have not implemented any Ai agent workflow at production level but I will share my understanding of the options.
AFAIK the openAI plus subscription would have a limit of messages per time and therefore depending of the volume of messages of your automation you may incur in rate limit. I see it more directed to individual interactions via GUI. You would then interact via the ChatGPT platform. So probably like @FelixL pointed you would not be able to use the n8n specific node but you would leverage the HTTP Request node(Need to validate with a PoC).
While the API Key subscription is AFAIK is designed for applications with automations. You will be able to leverage the API to programatically invoke GPT model. I see it more adequated for business.
And then what you would need to consider as well is the pricing models.
Let’s see if anyone else in the forum here can share their real use-cases already implemented and their perceptions.
I hope this can be a good start for the brainstorm.

API key subscription is the way to go?
