Making AI Make Sense

Alice Robert

Welcome to Kai.community, where we explore the evolving relationship between human systems and artificial intelligence. I’m Alice Robert—Anthrobotist by function, ever-curious by design—here to question what technology is becoming and how it reflects us.

Siva

And I’m Siva Narendra, engineer by training, innovator by conviction. Together, we examine how collaborative advances in computing, AI, and robotics can drive systems that are not only intelligent—but inherently human-centric. Let’s begin.

Siva

This is episode 2 on Making AI Make Sense. Let’s start with a simple but powerful question. What do large language models—these LLMs like GPT-4o, Gemini 2.5—really do when they generate text?

Alice Robert

I mean, they seem almost magical, don’t they? Like they actually understand what we’re asking.

Siva

Exactly, but that’s the thing. They don’t really understand. What they’re doing is predicting the next most probable word in a sentence, based on the patterns they’ve seen during training. Essentially, they’ve learned relationships between words by analyzing billions of data points—books, articles, websites, you name it.

Alice Robert

Okay, so it’s kind of like they’re guessing? But at a super advanced level?

Siva

Kinda, yeah. Think of it like a very sophisticated autocomplete system. When you type something on your phone, it suggests the next word. LLMs do that too, except, instead of one word, they do it one token, which could be a word or part of one, at a time to build these long, coherent responses.

Alice Robert

That makes sense, but I’ve seen them go way beyond just suggesting the next word. Like, they can write essays, scripts—even poetry.

Siva

Right, because they’ve been trained on massive amounts of data, which teaches them not just grammar but style, tone, even cultural nuances. The funny part is—it’s all probabilities. They don’t think, they don’t plan the way we do; everything they generate is a result of what probability says is most likely based on their training.

Alice Robert

And they can still mess it up sometimes. I actually tested this for a research article I was preparing—

Siva

Oh no!!!! What happened?

Alice Robert

Well, I asked it to give me a supporting quote from a historical figure, and it came up with the perfect line. It was eloquent, convincing. But here’s the kicker—it wasn’t real! That quote didn’t exist anywhere.

Siva

Ah, the infamous hallucinations! That’s a classic example. It sounded right because the model has seen similar language patterns, but it had no way to verify if that quote was authentic. It just stitched something together that seemed plausible.

Alice Robert

And, honestly, that’s a little scary. I mean, how many people take these answers at face value without realizing how that guesswork works?

Siva

Exactly, and it’s one of the biggest challenges in using these models responsibly. They’re brilliant at mimicking human language, but that brilliance can make it harder to spot when they’re wrong.

Alice Robert

It’s fascinating, but also unsettling. Why can’t these language models, as powerful as they are, just stick to the facts instead of hallucinating sometimes?

Siva

It’s a fundamental trade-off. At their core, these models are probability engines—they’re optimizing for what’s most likely to come next, not what’s true. During training, they’re exposed to massive datasets and learn patterns, but that data isn’t always accurate, and they don’t have an inherent mechanism for fact-checking. So, when they generate, they’re essentially guessing based on what they’ve seen before.

Alice Robert

Right, but isn’t that a bit of a design flaw? I mean, if they’re just guessing, how are they supposed to be reliable?

Siva

Not so much a flaw, but more of a limitation of the approach. These models aren’t trying to know the truth—they’re trying to sound fluent. And “sounding right” can sometimes backfire. Like when they output fictional quotes or made-up data because it aligns with what’s probable, not verifiable.

Alice Robert

Can the randomness in their process make it worse? Like, does the model get more unpredictable if you, I don’t know, tweak some settings?

Siva

Absolutely. That unpredictability often comes down to the 'temperature' setting. It’s like a dial for creativity versus accuracy. At a low temperature, the model becomes very focused, almost deterministic—it’ll choose the most likely continuation every time. But the higher you crank up the temperature, the more adventurous it gets, pulling in less likely, often surprising, continuations.

Alice Robert

Ah, so it’s kind of like choosing between playing it safe or taking a creative risk?

Siva

Exactly. And it’s situational. For example, imagine a bank using a high-temperature setting to brainstorm edgy marketing slogans—

Alice Robert

That sounds fun. “Your Money, Our Imagination,” or something wild like that.

Siva

Ha, close enough. But then, when they switch gears to writing compliance documents that need precision, they drop the temperature down to zero. There, the output has to be factual and structured, a totally different need.

Alice Robert

That makes a lot of sense. So, the art is really in knowing when to let it be creative versus when to keep it grounded.

Siva

Precisely. It’s all about striking the right balance for the use case.

Siva

That balance we talked about becomes even more important when we start exploring techniques to make AI more reliable. One such method gaining traction is Retrieval-Augmented Generation, or RAG, which essentially lets a language model pull in real, external data during response generation. This way, its output is grounded in facts rather than just probabilities.

Alice Robert

Wait, so instead of the models just guessing based on their training data, RAG lets them look up information, like in real-time?

Siva

Exactly. Think of it like giving the AI access to a library while it’s answering your question. It’s no longer limited to what it was trained on, which could be outdated or incomplete. Instead, it searches for relevant documents or facts, brings those into the conversation, and then generates its response based on that input.

Alice Robert

That’s so interesting. I actually used something similar recently for fact-checking a story. I was writing about climate change policies, and the AI tool I tried pulled data straight from government reports. It felt like—as you’d say—a safety net.

Siva

Exactly, and that’s the power of RAG. It’s adding that layer of accountability. But let me add to that safety net analogy—you know how a trapeze artist still takes risks, but having a net allows them to make bolder moves? That’s what RAG does for AI. It gives models more confidence to be accurate because they’re standing on verifiable information.

Alice Robert

But okay, can we talk about Knowledge Graphs? They’re another really fascinating piece of the puzzle. How do they compare to RAG?

Siva

Oh, great question. Knowledge Graphs are like a mapped-out brain of structured facts. While RAG pulls information from unstructured sources like documents, Knowledge Graphs work by organizing data in entities and relationships—so you could ask, say, 'What’s the capital of Japan?' and the Graph will just give you 'Tokyo' without needing to search for it. It’s already stored as a defined fact.

Alice Robert

Wow. And because it’s structured, that also means less guesswork, right? The AI isn’t trying to interpret paragraphs of messy text—it’s pulling directly from, like, verified snapshots of reality.

Siva

Exactly. Plus, Knowledge Graphs can do more than just retrieve facts. They can act as fact-checkers to ensure consistency across a model’s output. If the AI says the capital of Australia is Sydney, the Knowledge Graph flags that and corrects it to Canberra. It's especially valuable in areas like finance or healthcare, where accuracy is non-negotiable.

Alice Robert

I can see how that might reassure people who are skeptical about AI’s credibility. It also makes me wonder—when you combine these tools with human oversight, does that mean trust in AI could shift dramatically?

Siva

Without a doubt. What we’re moving toward isn’t about replacing human judgment but bolstering it. RAG and Knowledge Graphs make AI less of a confident guesser and more of a collaborative assistant. When humans and AI work together—humans bringing critical thinking and AI bringing speed and scale—you’ve got something really powerful. It’s trust by design.

Alice Robert

And honestly, that feels hopeful. Like, the more we use these tools responsibly, the more we can put AI to work solving the big, meaningful problems without losing confidence in the answers.

Siva

Exactly, Alice. And making sure the system is built with transparency, accountability, and collaboration is key to ensuring it serves humanity, not the other way around. With RAG and Knowledge Graphs, we’re seeing the beginning of that shift. It's exciting to think about where this could lead.

Alice Robert

On that note, I think we’ve covered some really important ground today. From how language models think to how they can be made smarter—and frankly, safer with tools like RAG and Knowledge Graphs. As a parting thought could you tell our listeners what steps they should consider as they use GenAI tools?

Siva

That is great question. I recommend "Guide, Edit, Enhance" or GEE principle. Guide, Edit, Enhance is a rapid-fire loop for trustworthy AI writing. Guide means pointing the model with a crystal-clear prompt—scope, style, and must-cover points—so its first draft lands close to the target. Edit is the safety net: you or a second pass fix facts, tighten structure, and trim fluff. Enhance kicks the process back to the top—feeding the cleaned-up draft into the model with new instructions for tone, depth, or visuals. Leverage RAG and Knowledge graphs. Each spin through Guide and Edit layers on accuracy and polish, so in just a few iterations you transform raw AI text into publication-ready content—speed of light, but with human-level quality. And to our listeners, thanks for sticking with us as we unpack these complex but critical topics. Like we said earlier, AI is incredible, but it’s the intentionality behind how we use it that truly matters.
