Google Vertex node support of custom models from model garden

It would help if there was support in Google Vertex node for:

Foundation models from Google model garden.

My use case:

In our company we are using heavely Vertex AI to host foundation models, like:
Claude, Llama, Mistral etc.
I would really love to have support fundation models from google model garden in vertex AI node.
Right now when I try to use enabled models from model garden like:

  • llama-4-maverick-17b-128e-instruct-maas
    And node gives me response:
    Only models starting with ‘gemini’ are supported.
    n8n version
    1.112.4 (Cloud)

Any resources to support this?

Are you willing to work on this?
