How Large Language Models (LLMs) Work
Large language models (LLMs) are advanced AI systems capable of processing and generating human-like text. By analyzing vast amounts of data, LLMs understand language patterns and can predict the next word in a sequence, summarize content, or even engage in complex conversations. This powerful technology forms the backbone of applications ranging from chatbots to content creation tools. Learn about how these models operate, from the basics of tokenization and embedding to the more advanced concepts like attention mechanisms and hardware acceleration. Explore the essential components that make LLMs a key driver in artificial intelligence innovation.
What is AI
Artificial intelligence (AI) enables solving complex problems without explicit solutions. Instead of defining step-by-step instructions, AI models learn through training on examples, identifying patterns, and producing results. This approach is especially useful when creating algorithms for tasks where traditional programming methods fall short.

What is Tokenization in AI
Tokenization converts words into numbers for AI models. Instead of handling individual characters, tokenization maps entire words or word fragments to numerical equivalents, reducing computational complexity. This allows large language models to efficiently analyze and predict text while treating words as cohesive units, improving performance.

What is Embedding in AI
Embedding represents the meaning of words as numerical vectors for AI models. Each vector encodes various attributes of a word (e.g., "cat" with four legs and fur) using directional values. This approach helps AI process not just words but their semantic relationships, enabling more nuanced understanding and responses.

What is Rotational Positional Embedding (RoPE) in AI
Rotary Positional Embedding (RoPE) encodes word order in text for AI models by rotating vectors representing words. Each rotation reflects a word's position in a sequence, preserving the distinction between phrases like "hello world" and "world hello." This method ensures positional context in language processing without altering vector magnitude.
