Parameters
What is Parameters?
The numerical values (weights and biases) inside a neural network that are adjusted during training. A model's parameter count is often used as a rough measure of its scale — GPT-3 had 175 billion parameters; larger models have hundreds of billions or more.
Example in practice
When a technology vendor claims their AI has "70 billion parameters", they are signalling the model's scale — a CTO should treat this as one data point alongside benchmark scores and actual task testing.
