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
- 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.
- 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).
