Inference
Weights
The numerical parameters inside a neural network that are learned during training.
In depth
The numerical parameters inside a neural network that are learned during training. Weights determine how the network transforms input into output. When people say a model has 70 billion parameters, they mean 70 billion weights. Releasing model weights publicly is what makes open-source AI models possible, since anyone with the weights can run inference without depending on an API provider.
Example
In practice, developers reach for Weights when they need the capability described above as part of an AI feature or workflow.
