What Are AI Agents?

Unlike basic chatbots, AI agents can autonomously interpret queries, manage sub-tasks, and integrate with external systems. While popular conversational services like OpenAI ChatGPT, Bing AI Chat (Microsoft Copilot in Edge), or Google Bard (Gemini AI) can handle Q&A or general content generation, AI agents often chain multiple steps, call APIs, or spin up additional “sub-agents.” This depth of autonomy is why they’re gaining traction in coding, marketing, operations, and even personal productivity.

NOTE: Enterprise Data Hygiene & Processes

In the world of AI agents, the adage “garbage in, garbage out” isn’t just relevant—it’s supercharged. If your enterprise data is disorganized, outdated, or rife with errors, these agents will inevitably produce flawed or biased outputs. Any many cases, they simply won’t work at all! Maintaining pristine data hygiene, robust governance, and well-defined processes is critical. Clean, carefully curated data ensures your AI initiatives remain accurate, reliable, and actually do the things you expect it to do.

This isn’t just true for your quantitative data warehouses. It’s also true for all of your qualitative data warehouses – we’re talking about your project tracking platforms, unstructured internal communications, internal documentation, written procedures, legal documents, presentations, strategy decks, and so on. The age of AI has dawned at it has shown us that qualitative data deserves as much attention and quantitative.
