How does AI actually learn? By rolling downhill.
Every AI you've used, ChatGPT included, learns with the same idea: gradient descent. Watch it in 64 seconds on Instagram, with a ball, a valley and zero equations.
- 1Make a guess
- 2Measure how wrong it is: the loss
- 3Take a small step downhill, then repeat
Try it
Roll the ball to the bottom
Set the learning rate, then step. Too small and it crawls. Too big and it bounces right past the answer.
Step
0
Loss
7.84
Just right: steady steps to the bottom
Each step moves the ball by learning rate × slope. The loss here is x², so the slope at any point is 2x.
