100 ChatGPT Prompts & Commands: The Ultimate List for Coding, Marketing, Video & Business

What this article covers

• 100 tested ChatGPT prompts and command codes across 10 categories.
• Slash-style short commands (/optimize, /template, /matrix, /table), usable as prompt prefixes.
• Per category: concrete commands with example prompts.
• How to customize the codes and combine them with system prompts.

Introduction

The most effective ChatGPT users don’t work with long-form sentences. They use command codes: brief, precise directives that tell the model exactly what to do. /optimize, /table, /matrix, /template - these prefix-style prompts are reproducible, faster to type, and deliver more consistent results than free-form writing.

This list contains 100 such codes across 10 categories, with prompt text you can use directly. They work with ChatGPT (GPT-4o, o3) and can be adapted for other models. See also the Claude version and for local models the Ollama prompt engineering guide.

How the codes work

A command is a prefix + your input. Example:

/optimize

ChatGPT interprets the command as an instruction and the rest as input. You can combine them: /optimize as table or /matrix with 3 options.

Commands stack, each one adds a rule. Pro tip: save frequent combinations as Custom Instructions or GPTs so they’re always active.

For local models

The codes work with Ollama and local models too. Instead of repeating them per message, put them in the system prompt. See System Prompts and Prompt Engineering.
