From LLMs to hallucinations, here’s a simple guide to common AI terms

The rise of AI has brought an avalanche of new terms and slang. Here is a glossary with definitions of some of the most important words and phrases you might encounter.

As organizations rush to move AI into production, they’re finding that the tools they rely on to monitor traditional software don’t translate cleanly to AI systems. The reason is fundamental: AI doesn’t fail as software does. It doesn’t throw clean error codes or follow predictable execution paths. It drifts, hallucinates, and degrades in ways that are often subtle, intermittent, and hard to reproduce. The result is a growing gap between what teams think observability should provide and what current tools actually deliver. The uncomfortable truth? The AI observability tools we have today are built for yesterday’s problems. To understand where the industry is headed, we need to look at where it is today and why that’s not enough. AI observability today: The era of evals Today’s AI observability landscape is dominated by one concept: evaluation. Most tools focus on scoring model outputs after the fact. They rely on test datasets, human graders, or, increasingly, “LLM-as-a-judge” approach

Once again, AI proves to be an unreliable source of information about AI.

Years ago, right-wingers coined the phrase “Trump Derangement Syndrome” (TDS) to describe people who hate US President Donald J. Trump. (I think it better describes the president’s outlandish, truth-challenged statements and the followers who think he can do no wrong.) What’s really deranged is his recent AI executive order. First, a little history. As you may recall, Trump often (and loudly) trashed his predecessor’s Executive Order 14110, which had demanded “safe, secure, and trustworthy” AI. That Biden Administration order was replaced last year by Trump’s own “Removing Barriers to American Leadership in Artificial Intelligence” directive; it basically let US AI companies do whatever they wanted in the name of innovation. Then, a little thing called Anthropic Mythos came along — and scared the pants off even AI’s biggest fans. Seemingly in response, someone in the federal government decided that letting AI companies do whatever they want might not be the brightest policy.  Or, did t

Here, we explain what AI hallucinations look like, why they happen, and how you can check whether a source actually exists.
