    <p className="mb-4">
      Modern AI systems — from Large Language Models (LLMs) to Generative AI for images or audio, and Agentic AI — all depend on one crucial ingredient: <strong>data</strong>. The way data is prepared, curated, and managed for these systems has evolved significantly compared to traditional data engineering for business intelligence or rule-based systems.
    </p>
    <p className="mb-4">
      This page covers best practices in data engineering tailored to LLMs, Generative AI, and Agentic AI, and compares their workflows both with each other and with traditional data pipelines.

    <h2 className="text-xl font-bold mb-4">Key Differences from Traditional Data Engineering</h2>
    <ul className="list-disc list-inside pl-4 space-y-2">
      <li>Focus on unstructured/multimodal data vs structured tabular data</li>
      <li>Objective is model performance, not just data accuracy or dashboards</li>
      <li>Use of synthetic data, data augmentation, and self-supervised learning</li>
      <li>Need for high-throughput, parallel pipelines (image/audio/text/token handling)</li>
      <li>Model-aware metrics (bias, representativeness) instead of only schema/data type checks</li>
      <li>Data feedback loops, online adaptation, and real-time inference support</li>
    </ul>

    <h2 className="text-xl font-bold mb-4">Conclusion</h2>
    <p className="mb-4">
      Traditional data engineering focuses on correctness and reporting from known structured data. In contrast, modern AI data engineering is about scalability, diversity, and adaptability – managing messy, complex, and evolving data to fuel intelligent systems.

      Engineers today must master not only data pipelines, but also how those data choices impact models and downstream AI behaviors.
