Summary : Learn five practical prompting techniques—role prompting, few-shot examples, chain-of-thought, guardrails, and self-consistency—that help you get precise, reliable, and safer outputs from AI tools like ChatGPT. Use these methods to turn generic answers into expert-level responses. Why prompts matter Great AI output starts with a great prompt. If your results feel generic or off-target, the issue is rarely the model; it is the input. Prompt engineering is the practical skill of crafting inputs so the model reliably produces the outcome you want. These five techniques will help you move from reactive questioning to deliberate instruction. View my  Prompt Engineering & Prompting Techniques video . Then read on. 1. Give the AI a job title: Role Prompting Assign a persona or role to the model to frame its tone, vocabulary, and depth. For instance, asking an AI to "act as a cybersecurity expert" leads to technical, risk-focused answers. Role prompting is a quic...

Summary : A clear post about the core concepts behind generative AI - emergent abilities, chain-of-thought, hallucinations and RAG, human-alignment via RLHF, and foundation models. Practical examples and tips for using these ideas responsibly and effectively. Introduction Generative AI tools like ChatGPT feel effortless: you type, they answer. That ease hides a complex stack of engineering and surprising mechanics. Understanding how these models work helps you get better results, spot their limits, and use them safely. View the Generative AI Builder's Journey first. Next, this post explains five essential concepts that drive generative AI today and what they mean for everyday users and builders. 1. Bigger Is Not Just Better - It Can Be Unpredictably Different In many systems, adding scale produces steady improvement. With large language models (LLMs), scale sometimes unlocks new, unexpected skills called emergent abilities. A small model might fail entirely at a task, while...

Summary : Context Engineering is the architecture that lets AI remember, personalize, and act reliably across sessions. Beyond crafting clever prompts, it assembles the right data, tools, and memory hygiene so AI systems behave like thoughtful personal assistants,  and not forgetful librarians. Beyond RAG: Why Most AI Forgets the Moment You Close the Chat We’ve all had the same experience: a helpful conversation with an AI assistant, then a fresh chat that treats us like a total stranger. Every interaction feels like the first. That friction isn’t just annoying, but it also exposes a core architectural limitation of many AI systems. By default, Large Language Models (LLMs) operate as essentially stateless systems. They reason inside a temporary "context window" that vanishes when the session ends. If you want an AI that remembers, learns, and personalizes over time, you must design for state. That’s what Context Engineering does: it builds the framework that transforms...
