Documentation

n8n-nodes-nvidia-nim-chat

Use NVIDIA NIM inference microservices as the chat language model in n8n AI Agent and AI Chain workflows. The node speaks the OpenAI-compatible API surface that NIM exposes, so you can point it at NVIDIA-hosted endpoints or your own NIM deployment.

n8n is a fair-code licensed workflow automation platform.

Contents

Installation

  1. In n8n, open Settings → Community nodes (or your admin's equivalent).
  2. Install the package n8n-nodes-nvidia-nim-chat.

For detailed steps, security notes, and Docker or CLI options, see the official guide: Installing community nodes.

Quick start

  1. Create credentials
    In n8n, add NVIDIA NIM Chat API credentials (see Credentials).

  2. Add the node
    Add NVIDIA NIM Chat Model to your workflow.

  3. Connect it
    Wire the node's Model output to the Chat Model input of an AI Agent or AI Chain node (this node has no regular inputs; it only supplies the model).

  4. Pick a model
    The Model dropdown is loaded from your GET /models endpoint. Choose the model your NIM deployment exposes.

  5. Optional tuning
    Open Options for temperature, top-p, max tokens, retries, timeouts, and response format (text or JSON).

If you are new to n8n, the Try it out docs help you run your first workflows.

What this node does

Aspect Details
Role Supplies a chat LLM to AI Agent / AI Chain (output type: AI language model).
API OpenAI-compatible chat completions against your configured Base URL.
Models List is fetched dynamically from the API so it matches your account or self-hosted NIM.

JSON responses: If you set Response Format to JSON, include the word json in your prompt (as noted in the node UI) so the model returns valid JSON.

Credentials

Create NVIDIA NIM Chat API credentials in n8n:

Field Description
API Key Your NVIDIA NGC API key. Create or manage keys at NVIDIA NGC. Stored and sent as a Bearer token in the Authorization header.
Base URL Root URL for the OpenAI-compatible API. Default: https://integrate.api.nvidia.com/v1. Use your own base URL if you run NIM on-premises or in your cloud.

Use Test on the credential to verify access; it calls GET /models on your base URL.

Compatibility

  • n8n: Use a version that supports community nodes and built-in AI Agent / AI Chain (and LangChain-style model inputs). This package targets n8n node API version 1.
  • A specific minimum n8n version is not pinned in this repo; if something fails to appear in the editor, upgrade n8n first.

Developing this package

Clone the repository, install dependencies, then use the n8n node CLI:

npm install
npm run build    # production build → dist/
npm run dev      # local n8n with this package (see n8n-node dev docs)
npm run lint     # eslint via n8n-node
