  1. ChatGPT

    Start here: ChatGPT is the tool that brought AI assistants into everyday life, and understanding what it is gives you a concrete anchor for everything that follows.

  2. OpenAI

    Now meet the lab behind ChatGPT — knowing who OpenAI is and what they're trying to do puts the product in context.

  3. Anthropic

    A second major lab with a different philosophy — reading about Anthropic shows that there's more than one approach to building AI.

  4. Claude

    Claude is Anthropic's assistant, so this step connects the lab you just read about to the product it ships.

  5. Reinforcement Learning from Human Feedback

    This is the training technique that turns a raw language model into a helpful, well-behaved assistant — the key step behind both ChatGPT and Claude.

  6. Chain-of-Thought Reasoning

    One of the most important ideas in how modern AI reasons: letting the model think through a problem step by step before answering.

  7. Retrieval-Augmented Generation

    Finish with RAG — the technique that lets AI assistants pull in outside information, bridging the gap between a model's training and the real world.
