Welcome to the first installment of our blog series on generative AI! Let’s dive into language models—those fascinating algorithms that make machines sound almost human. They’ve transformed the way we interact with technology, allowing it to generate responses like a slightly less glitchy robot. In this series, we’ll break down the concepts behind these models in a straightforward way, steering clear of jargon overload while exploring the exciting world of AI.

More Parameters = More Memory (AKA the Model’s Brain)

When we say "parameters," we mean the settings inside the model’s brain. The more it has, the more memory it needs. So, a bigger brain means it eats up more memory. But the upside? It can store more info and give smarter answers—so it’s less likely to mix up "your" and "you’re."

Have you seen people talking about 8 billion parameters, 70 billion parameters? That’s what they’re referring to—

Prompts: The Magic Words

Think of a prompt as your model’s to-do list. You tell it what to write, and voilà, it does. Want a 500-word essay on the Taj Mahal? Just say something like: "Hey, can you write a 500-word story about the Taj Mahal in India?"

Simple, right? Until the model decides to take a detour into the history of Mughal emperors and conveniently ignores that 500-word limit. Good luck reeling it back in!

Context Window: The Model’s Goldfish Memory

Ever notice how your chatbot sometimes forgets what you were talking about? Yeah, that’s the context window at play. It’s the model’s short-term memory and it can only remember so much. If you chat too long, the beginning of the conversation gets tossed out like last week’s leftovers. Keep it short, or expect some weird plot twists.

Pro Tip: Bigger context windows help the model stay focused longer, but even then, it's not foolproof. Don’t get too attached to the consistency.

Completions: The Model’s Best Guess

“Completions” are just a fancy way of saying “the model’s response.” Ask it something, and it’ll give you an answer based on whatever data it’s been trained on. But how good the answer is depends on how clear your prompt is. Vague question? Vague answer. It’s basically the model’s way of saying “I tried.”

Inference: The Tech Behind the Curtain

“Inference” is the process where the model takes your prompts, parameters, and context (no magic dust, unfortunately) and generates text. It breaks the input into smaller pieces called "tokens" and uses "attention mechanisms" to focus on the most relevant parts. This helps the model stay on track and produce coherent responses – basically, it’s the model’s way of trying not to embarrass itself.

The Bottom Line

So there you have it. Parameters, prompts, context windows, completions, and inference – the basics of how language models do their thing. Next time you chat with an AI, just remember, it’s working hard behind the scenes to almost understand you. But hey, we’ll get there someday. Probably.

Cheers Until Next Time!
