This post explains why RAG exists, how it works, and what problems it actually solves — without turning it into a tooling tutorial.https://blog.girishshekhar.com/posts/llms-and-how-our-work-is-changing/4-why-llms-fail/Wed, 05 Apr 2023 00:00:00 +0000https://blog.girishshekhar.com/posts/llms-and-how-our-work-is-changing/4-why-llms-fail/Large Language Models often fail in ways that feel inconsistent or irrational. This post explains why those failures are not bugs, but natural consequences of probabilistic systems trained on language — and what that means for real product and system design.https://blog.girishshekhar.com/posts/llms-and-how-our-work-is-changing/2-how-llms-work/Wed, 22 Mar 2023 00:00:00 +0000https://blog.girishshekhar.com/posts/llms-and-how-our-work-is-changing/2-how-llms-work/A deeper look at how Large Language Models actually work — focusing on tokens, transformers, and training stages — explained in a way that helps engineers, product managers, and technical leaders reason about behavior and tradeoffs.https://blog.girishshekhar.com/posts/llms-and-how-our-work-is-changing/1-why-llms-changed-the-game/Tue, 07 Mar 2023 00:00:00 +0000https://blog.girishshekhar.com/posts/llms-and-how-our-work-is-changing/1-why-llms-changed-the-game/Large Language Models feel different from earlier machine learning systems. This post explains why — focusing on tokens, training data, self-supervision, and the architectural patterns that changed how we build software.
