AI agents or AI in flow engineering is nothing but a system. All variations are agentic systems, but draw an important architectural distinction between workflows and agents:
- Workflows are systems where LLMs and tools are orchestrated through predefined code paths.
- Agents, on the other hand, are systems where LLMs dynamically direct their own processes and tool usage, maintaining control over how they accomplish tasks.
