n8n AI Agent Node in 2025: Complete Guide to Building Smart Workflows
The n8n AI Agent Node brings reasoning, memory, and adaptive decision-making to your workflows. Instead of just running prompts, the AI Agent Node lets automations think — analyzing context, calling APIs, and making choices dynamically using models like GPT-4o, Claude 3.5, or Gemini 1.5 Pro.

What Is the n8n AI Agent Node
Introduced in the 2025 update, the AI Agent Node is designed to make n8n workflows more intelligent. It connects with major AI providers, processes context dynamically, and can interact with other nodes through reasoning steps. Think of it as a brain embedded inside your automation.
Key Features
- Multi-model support for OpenAI, Anthropic, and Google Gemini.
- Context persistence for long-running workflows.
- Tool-calling support — agents can trigger other nodes or fetch APIs autonomously.
- Built-in memory and function calling support for advanced AI logic.
- JSON-based input/output compatible with existing workflows.
How to Use the AI Agent Node
- Open your n8n dashboard and create a new workflow.
- Add the AI Agent node from the AI section.
- Choose your preferred provider (OpenAI, Claude, or Gemini).
- Define the prompt or task logic (for example: summarize, generate text, or analyze data).
- Connect the node to an action — such as sending a Slack message or updating a Notion page.
- Run a test execution and monitor the reasoning path in logs.
Example Workflow: AI Support Agent
Imagine connecting a WhatsApp or Gmail webhook to the AI Agent Node. Every incoming message is analyzed for tone and intent. The agent crafts a reply using OpenAI, checks customer data in Google Sheets, and sends a personalized response back — all in seconds. This setup turns n8n into an automated AI-powered customer assistant.
Best Use Cases
- AI email summarization and tone analysis
- Chatbot automations across WhatsApp, Telegram, and Slack
- Lead enrichment and qualification using GPT logic
- Smart content creation with AI-driven branching logic
- Decision-based workflow routing using contextual reasoning
Verdict
The n8n AI Agent Node transforms automation from static triggers into dynamic, context-aware systems. By combining structured workflow logic with adaptive AI reasoning, it’s the most powerful way to blend human-like decision-making with automated speed. Whether for marketing, support, or data ops, it’s the node that defines n8n’s AI era.
