Embeddings, Vector database Agent,, RAG & MCP: How Modern AI Systems Actually Work

This video is Sponsored by Twingate → https://twingate.plug.dev/eqoeK2F
It breaks down the complete AI stack in a simple, system design perspective.

We go step by step:
• Embeddings: how AI understands meaning
• Vector Databases: how AI remembers
• Agents: how AI decides and acts
• RAG: how AI stays accurate and up-to-date
• MCP: how AI connects to real-world tools

By the end, you’ll have a clear mental model of how modern AI systems actually work.
