**TLDR:** An activation-like structure that filters linear signals through a gating mechanism to enable more selective information flow.

<p>A Gated Linear Unit differs from classical activation functions by including a gate that learns how much information should pass through. This selective transmission can be especially effective in sequence modeling, language tasks, and modern Transformer variants. Rather than fully transforming the linear signal, it performs a controlled opening and closing, which may offer more flexible expressivity in some settings. It is one of the important structures that blurs the line between activation and architectural control.</p>
