Why can't I connect the Hugging Face Inference Model node to the AI Agent node in n8n?

I'm trying to connect the node "Hugging Face Inference Model" to the node "AI Agent" in n8n, but they appear to be incompatible. When I attempt to connect them, I get the error message below:
I am using:
- n8n version: 1.81.0
- Database: Postgres (default is SQLite)
- Running n8n via Docker on Linux
How can I resolve this compatibility issue between the two nodes?

The error you're encountering is due to the fact that the AI Agent node expects a connected Chat Model sub‐node, but the Hugging Face Inference Model node isn’t recognized as one. In n8n the AI Agent node is designed to work in tandem with a proper Chat Model sub‐node (for example, one of the available Chat Model nodes) rather than a root node like Hugging Face Inference Model.
How to resolve this issue:
-
Use a compatible Chat Model node:
Instead of trying to connect the Hugging Face Inference Model node to the AI Agent node, click the + Chat Model button on the AI Agent node. This will allow you to select one of the supported Chat Model nodes that are compatible. -
Reconfigure your workflow:
Adjust the workflow so that the AI Agent node receives input from a proper Chat Model sub‐node. The AI Agent node isn’t set up to accept input directly from root nodes like Hugging Face Inference Model.
By adding and configuring a compatible Chat Model sub‐node, the AI Agent node will have the expected connection, and the error should be resolved.
