Your First Break in AI
FBA Lab is an interactive study lab where you learn how AI models are actually trained — from real training code, not slides. Every concept comes four ways: watch, read, deep-dive with Rune (your AI tutor), and play graded challenges.
No setup. No GPU required. Study entirely in your browser.
Every concept, four ways
FBA Lab teaches each idea from real training code — so it sticks whichever way you learn best.
Watch
Video lessons that walk through each decision.
Read
Written explanations you move through at your own pace.
Rune
Deep-dive any concept with Rune, your AI tutor.
Play
Graded challenges that earn verified skill fluency.

Three ways in: the curriculum, the lab, and the arena.
Roadmap
The full curriculum. Learn how AI models are actually trained across three acts — Model Training Fundamentals, AI Systems Optimization, and World-Record Training — grounded in real code and compared to frontier open models like OLMo, Marin, and SmolLM3.

The hands-on lab. Train a GPT-2 small model from scratch to a validation loss below 3.28, then beat your time across six successive optimizations — each step changes exactly one thing, so you isolate every bet.

The live competition. Take human-graded challenges, earn skill fluency verified by a real grader, and climb the leaderboard as you build an LLM. Spectating is free — no login needed.
Enter the ArenaWho FBA Lab is for
Students, professionals, career switchers, and the simply curious. It doesn't matter what you studied or where you work — what matters is that you're ready to learn by doing. Work through the lab, build in the open, and let your work speak for itself.
FBA Lab is led by FireHacker (Amardeep Singh Sidhu), founder of AIEdx. Every step comes four ways — video, written lessons, an AI tutor, and graded challenges — so you can learn the way that works for you.
