This is what happens when running inference on a neural network:
Input (list of numbers) -> (Bunch of math operations) with (other numbers) -> Output (also a list of numbers)
This applies whether you are talking about image classification, image generation, text generation etc.
The model defines what the "(Bunch of math operations)" part is. As in, do these multiplications, then add, then a tanh operation etc.
The weights define what the "(other numbers)" are. Training is the process of figuring out these weights using various methods - some of which involve example inputs/outputs (supervised learning), others don't require examples (unsupervised or self-supervised learning).
