Stop Building AI Agents With Workflows

By n8n

Categories: Tools, Product

Summary

n8n separates AI automation into three distinct patterns: fully deterministic workflows for reliability, semi-deterministic workflows with AI as specific steps, and autonomous agents with freedom to choose tools—and they work together, not separately, enabling teams to embed AI agents directly into production systems.

Key Takeaways

  1. Use deterministic workflows for production systems that must run fast, cheap, and reliably the same way every time—this becomes essential as real systems scale, even if you don't anticipate needing it upfront.
  2. Semi-deterministic workflows treat AI as a defined step with a specific job (classification, data filling, multi-tool tasks) rather than letting it roam freely—this hybrid approach gives you control while leveraging AI where it adds value.
  3. Agents operate as autonomous coworkers with defined capabilities, skills, and personality—give them tools (Miro, Notion, etc.) and let them decide when to use them, deployable directly into Slack or other team workflows.
  4. Stack these patterns together: any workflow becomes a tool for your agent, and agents can be embedded inside deterministic workflows via canvas integration, creating layered automation that's both flexible and controlled.
  5. Avoid building agents with workflows—n8n's dedicated agents interface provides better UX for AI assistants than trying to construct agents as workflow logic, especially for chat interfaces or support bots.

So at the top level in n8n, we have these 3 core things. Credentials, which is the connections to all the other apps managed throughout n8n. The workflows for the deterministic logic and controlled AI use, which includes agent nodes in the canvas, and now also agents. And the other stuff is important [laughs] too, but we'll just focus on the differences between these 3 things for this video. Agents is our newest offering and the one where AI has the most freedom in n8n. You can define an agent to have a set of capabilities, skills, and personality to help with tasks that don't have specific predefined steps. Let's say, for instance, I want an agent to be a marketing assistant for my team. I can give it tools like our Miro and Notion so it can work with us, give it skills like Anthropic's m…
