OpenAI New Agent SKD & N8N

Questions

As some you know, OpenAI just launched a new API / SKD for Agents. At first look, it seems similar to what N8N has been doing for few months now. There could be changes in some of the N8N modules especially because they introduced the Response API end point. I think this will eventually replace the chat completion API.

https://platform.openai.com/docs/guides/responses-vs-chat-completions

"We’re working to achieve full feature parity between the Assistants and the Responses API, including support for Assistant-like and Thread-like objects and the Code Interpreter tool. When complete, we plan to formally announce the deprecation of the Assistants API with a target sunset date in the first half of 2026.

Upon deprecation, we will provide a clear migration guide from the Assistants API to the Responses API that allows developers to preserve all their data and migrate their applications. Until we formally announce the deprecation, we’ll continue delivering new models to the Assistants API."

I personally feel that N8N architecture allow us to use different LLMs and not just stay with one.

Does any one see any areas that this new SKD improves over what we currently have in N8N?

To your confusion:

Chat Completions API, Response API, and Assistants API are different.

The Chat Completions API is not going away
The Chat Completions API is an industry standard for building AI applications, and we intend to continue supporting this API indefinitely. We’re introducing the Responses API to simplify workflows involving tool use, code execution, and state management. We believe this new API primitive will allow us to more effectively enhance the OpenAI platform into the future.

But yes, the Response API will someday replace the Assistants API, the Chat Completions will never be replaced.

The new SDK might provide some value, but as most models have the ability for tool calls and n8n’s agent node already allows to setting such, I don’t think the Response API will change things too much. Very useful to have computer use as built in tool tho.
