Don’t Build Another AI Agent Until You Understand This AI Agents vs AI Workflows ~ n8n



AI Summary

Summary of Video: AI Agents vs. AI Workflows

Introduction

  • Surge in popularity of AI agents leads many to automate workflows unnecessarily.
  • Overusing AI agents increases costs, complexity, and reduces reliability.
  • Goal: Clarify differences between AI agents and AI workflows.

AI Agents

  • Definition: LLM (Large Language Model) wrapped in a framework capable of executing tool calls.
  • Process: Receives input, decides on tool calls, processes outputs, and generates responses.
  • Characteristics: Autonomous, undeterministic (can produce different results for the same input).

AI Workflows

  • Definition: A traditional workflow enhanced with AI, following predetermined steps.
  • Process: Executes a fixed sequence, predictable and consistent in behavior.
  • Characteristics: Deterministic, ensuring the same output for the same input.

Comparisons of Examples

  1. Email Labeling System:
    • AI Agent Approach: Multiple round trips to LLM for processing; higher cost and time.
    • AI Workflow Approach: Single classification step with subsequent actions based on predetermined logic; faster and cheaper.
  2. Complaint Processing System:
    • Demonstrated similar differences in cost efficiency and speed between both approaches.

Conclusion

  • Use AI workflows when tasks are deterministic to ensure reliability, reduce costs, and enhance efficiency.
  • AI agents are better suited for dynamic tasks but may introduce errors (5-25% mistake rate).
