Day 23 : From Code to Cognition: Transformers & LLMs : The Architecture Behind ChatGPT, Bard, and More
Opening: Why Understanding the Architecture Matters Welcome to Day 23 of the “From Code to Cognition” series a daily exploration of the principles, patterns, and paradigms that shape intelligent systems. Today, we’re diving into the architecture that powers modern conversational AI: the transformer. For tech professionals whether you're already working in AI or considering a pivot grasping the fundamentals of transformers and large language models (LLMs) isn’t just intellectually satisfying. It’s a gateway to building smarter systems. It helps you evaluate model behavior, design better prompts, and contribute meaningfully to one of the most transformative fields in computing. This post offers a clear, structured walkthrough of the architecture behind modern LLMs, with practical insights and real-world relevance. No hype just the mechanics, implications, and opportunities. Part 1: What Is a Transformer, Really? Introduced in the 2017 paper “Attention Is All You Need,” the tran...
