Mastery Gate 3: draw and implement GPT closed-book

Mastery Gate 3: draw and implement GPT closed-book. Learn architecture, objective, training, and generation as one system and complete: Whiteboard, implement, and train on a new co

Learning objectives

  1. Explain what problem “Mastery Gate 3: draw and implement GPT closed-book” solves without hiding behind terminology.
  2. Trace the variables and causal links across architecture, objective, training.
  3. Complete “Whiteboard, implement, and train on a new corpus” and judge the result with evidence rather than intuition.

Core concepts

architecture

architecture is part of the lesson’s causal model. State its inputs, outputs, invariants, and failure mode; then verify it with a hand-check or a minimal experiment before moving to an optimized implementation.

objective

objective is part of the lesson’s causal model. State its inputs, outputs, invariants, and failure mode; then verify it with a hand-check or a minimal experiment.

training

training is part of the lesson’s causal model. State its inputs, outputs, invariants, and failure mode; then verify it with a hand-check or a minimal experiment.

and generation as one system

and generation as one system is part of the lesson’s causal model. State its inputs, outputs, invariants, and failure mode; then verify it with a hand-check or a minimal experiment.

Build and verify

Whiteboard, implement, and train on a new corpus

  • Predict: write the expected output, trend, or failure before running code.
  • Build: implement only the minimum components needed to answer the question.
  • Verify: compare with a baseline or trusted implementation; save seeds, parameters, and raw outputs.
  • Transfer: change one shape, dataset, scale, or workload condition and explain whether the conclusion still holds.
