  Definition & Capability ArtificialIntelligence (AI) refers to the simulation of human intelligence in machines programmed to think, reason, learn, and solve problems autonomously. Rather than executing rigid hardcoded rules, AI systems analyze data, recognize complex patterns, and make decisions in real-time context. Paradigm Shift Traditional Software: Input Data + Hardcoded Rules Fixed → Output AI & Machine Learning: Input Data + Desired Outputs → Learned Rules This shift enables software to handle fuzzy inputs like vision, natural speech, and chaotic financial markets.

  Generative AI &LLMs The Era of Foundation Models Generative AI shifts from analyzing existing data to creating entirely novel text, images, code, and audio based on learned statistical distributions. Large Language Models (LLMs) rely on Transformer architectures featuring self-attention mechanisms that process long-range context in text in parallel.

  RAG (Retrieval-Augmented Generation) Combinesexternal knowledge databases with LLMs to ground responses in accurate, private enterprise facts. Eliminates model hallucinations by dynamically injecting relevant context directly into prompt windows. AI Agents & Tool Calling Autonomous entities using LLMs as core "reasoning brains" to execute multi-step complex goals. Agents interact with real systems by calling APIs, browsing the web, executing code, and iterating on errors autonomously. RAG & AI Autonomous Agents
