Definition
The learned weights and biases in a neural network that determine how it processes input and produces output.In-Depth Explanation
Parameter count is often used as a proxy for model capability. GPT-4 is estimated to have over 1 trillion parameters. More parameters generally enable learning more complex patterns but require more compute for training and inference. Parameter-efficient methods like LoRA reduce fine-tuning costs.
Real-World Example
Llama 2 comes in 7B, 13B, and 70B parameter versions, with larger models generally performing better.
