How can I get this information? It’s shown in the chat model, but I can’t access this data in my workflow. [image] I’ve seen workarounds here in the community, but maybe now there’s an official way? Information on your n8n setup n8n version: 1.84.3 Database (default: SQLite): default n8n EXECU…

Hi I’m sure you can get it from the underlying tables: Here’s a workflow which was posted recently which is surely based on that: [圖片] Solved white_check_mark - How to Get LLM Token Usage from AI Agents Tips & Tricks Hey community! wave I’ve been trying…

I copied this workflow as-is into the same version (1.84.3) of n8n (community) and my output doesn’t have that part (tokenUsage) at all. Is there something you have enabled in your settings for your actual OpenAI account to make that appear in the response?

The information is in the OpenAI Chat Model node, not on the AI Agent node. Did you open that one? And that is the problem. The information is not on the output of the AI Agent, and I don’t know how to retrieve it from the chat model node :confused:

Ah, ok. Thanks for clarifying. It is kinda twice as annoying when you know something is there, but you can’t reach it.

In case you want to cross this off your list of things to try, or build on the idea and see if you can get it to work, this looked promising (a document got inserted), but the actual info wasn’t stored.

So the agent has access to the subnode token usage data? If you ask it, it will answer?

IDK. I just thought it would be worth a try. I would assume if anything in the workflow has access to the tokenUsage info from the model, it would be the agent. However, it would be a weird interaction. What I tried would essentially be telling the AI to return tool-usage instructions to the age…

Alguem ja tentou fazer a consulta por api direto no site da openai.com ?

Hi @solomon Is this what you’re looking for? [圖片] Can't set the path of the 'chat model' in 'AI Agent' step Help me Build my Workflow Hi @aminabudahab You will need to activate Return Intermediate Steps in the AI Agent node options [image] [image] …

Unfortunately no, @mohamed3nan What I’m trying to get is the information from the model node: [image] If I open this node I can see the token usage data: [image] But if I try to get that data on a subsequent node, this is all I see: [image]

Unfortunately that’s an estimator, not real data extraction from the workflow. @jcuypers From what I can see it gets the text, the AI model and sends to an external service to estimate the cost. Very smart, but still cumbersome.
