Weights

Friendly Description: Weights are the numbers inside a neural network that get fine-tuned during training. They are what the model actually "knows." If you imagine a recipe, the weights are like the precise measurements of every ingredient, perfected over many tries until the dish comes out just right. When people share an AI model, what they're really sharing is its weights.

Example: An open-source model release usually means the weights are made publicly available. Researchers and developers can download the file (which can be many gigabytes), load it into their own systems, and use the model immediately, because everything the model learned is captured in those numbers.
