In the early days of AI, we focused on "Prompt Engineering." Today, the focus has shifted to "Agentic Workflows"—the architectural patterns used to chain multiple AI steps together into a cohesive system.
Research has shown that an older, "weaker" model (like GPT-3.5) used in a sophisticated agentic workflow (with self-correction and multi-step planning) can often outperform a "stronger" model (like GPT-4) used in a single-shot prompt. This is because the *workflow* handles the complexity, allowing the AI to focus on one small, manageable task at a time.
An agentic workflow is designed to handle failure. If a model generates incorrect code, the workflow catches the error, feeds it back to the AI, and asks for a fix. This "iterative loop" is what transforms AI from a fickle toy into a reliable production tool. Moving from "prompts" to "workflows" is the biggest architectural shift in AI development today.
