Interactive walkthrough of every number in a tiny GPT
Original: Show HN: Every number in a tiny GPT, from one forward pass to one step of RLHF
A developer has published an interactive tool that shows every number inside a tiny GPT model, tracing the calculations from a single forward pass through to one step of RLHF fine-tuning. The project lets users inspect the arithmetic step by step, and it is drawing attention as a hands-on way to understand how transformer models and reinforcement learning training actually work under the hood.
Why now: People are discussing it because it offers an unusually transparent, step-by-step view of how GPT models compute and learn.
