Where would you like to start?
Start with six essentials.
What is Artificial intelligence?
An AI system infers from received inputs how to generate predictions, content, recommendations or decisions for explicit or implicit objectives.
What is LLM?
An LLM predicts a token or sequence of tokens, sometimes many paragraphs long.
What are Embeddings?
An embedding maps a discrete item such as a token ID to a dense vector of numbers.
What is RAG?
RAG lets an AI model look up relevant documents first, then answer from what it found.
What are AI agents?
An AI agent is a language model that chooses its own next steps and tools while it works through a task.
What is MCP?
MCP standardizes how AI applications connect to external context and tools.
