Watch on YouTubeThe Power of AI: A Green Apple Eats a Red Apple 🍏🍎
AI turns a simple idea into something strangely satisfying. A green apple comes to life, bites into a crunchy red apple, and reacts with realistic facial motion, texture, lighting, and ASMR sound.
Watch on YouTubeHow AI Agents Work: Tools, Memory, MCP, Guardrails
How AI agents work beyond the LLM: prompt → tool call → policy → runtime → observation.
Watch on YouTubeHow Vector Databases Work: Embeddings, HNSW & Semantic Search
Vector databases store embeddings so semantic search can find nearest neighbors by meaning instead of exact keyword matches. This visual deep dive explains ANN, HNSW, IVF, metadata filtering, hybrid search, reranking, and the retrieval step that powers RAG.
Watch on YouTubeRAG Explained: Why LLM Guesses Without Retrieval
What is RAG? Retrieval-augmented generation fetches document chunks with embeddings before the language model writes an answer.
Watch on YouTubeAI Embeddings Explained: Vectors Behind RAG Search
What are embeddings? They turn text into vectors so semantic search can find nearest neighbors by meaning, not spelling.
