# What is Dense Transformer?

*Artificial Intelligence · Last updated: November 10, 2026*

It is the standard Transformer architecture where all parameters are active at every step.

## Overview

Dense Transformer refers to the traditional structure where all computational units in a layer of an artificial intelligence model work collectively for every input. As input data passes through the model, the entire network is triggered, which requires high computational power. As the model's capacity grows, the energy and time consumed increase proportionally.

***Analogy:** This is similar to all employees of a factory entering the production line simultaneously for every simple incoming order.*

## How it works

After input texts are tokenized, they pass through all parameters of the model simultaneously via matrix multiplications. This process ensures a deep understanding of the data but consumes hardware resources heavily. Especially in large-scale models, this full participation creates a significant hardware cost.

## Where it is used

This architecture is widely preferred in standard large language models and basic text generation systems.

## Commonly confused with

It is frequently confused with the Mixture of Experts (MoE) architecture, where only the relevant part of the parameters is active.

## Questions and answers

**Why are Dense Transformer models slow?**

Because the entire network must work simultaneously for every word or operation, it creates a heavy load on the hardware.

**In which areas is it used?**

It serves as a fundamental building block in general-purpose natural language processing tasks and standard artificial intelligence infrastructures.
