Do I need math first?

No, fast.ai teaches top-down: you build models first and learn the theory as needed.

What should I know before starting fast.ai?

Comfortable Python is the main prerequisite; you can pick up the math along the way since the course teaches top-down. A GPU helps, but the free notebooks run on cloud services like Colab, so no local hardware is required.

Is the course still relevant with modern LLMs?

Yes — fast.ai teaches the deep-learning fundamentals and mental models behind the models you now prompt or fine-tune. Understanding training, transfer learning, and evaluation makes you far better at using and debugging LLM systems, even if the course predates today’s chat models.
