The Illusion of Memory: Why LLMs Can't Remember — and How We Trick Them

Large Language Models (LLMs) often feel like they remember past conversations or facts, but under the hood their memory works very differently from human memory. This article explores how LLMs handle context, why it seems like they remember things, and how engineers simulate memory for them.

Dynamic AI Agents Orchestration: A New Paradigm (No, it's not an MCP) — Part 1 The Future of Intelligent Automation and Real-World Integration

If you've ever tried building an AI agent using modern orchestration frameworks, you might have felt a strange sense of déjà vu — like you're back in the early 2000s dealing with DLL Hell. Back then, software broke because a tiny shared library had the wrong version or wasn't registered correctly.

Rethinking Workflows: How Choreography Empowers AI Agents to Collaborate Without a Boss

Picture a group of highly skilled professionals in one office. Each person is an expert in a particular domain — finance, marketing, customer service, logistics — yet there's no single manager telling them what to do. Instead, they each listen for signals relevant to their specialty (for example, a new sale happened or inventory is low) and take action immediately. …

The Math Behind the Magic: How Probability Powers Large Language Models Like GPTs Ever wondered what powers GPT-4? It's all about probability

Imagine you're about to flip a coin. Before you do, you might wonder: What's the chance it lands on heads? Or consider picking a card from a standard deck: What's the probability of drawing an Ace? These everyday questions tap into the essence of Probability Theory — a mathematical framework for quantifying uncertainty and making informed predictions.
