Today I’ll show you how to use ChatGPT-5 in the Cursor IDE and use it to take a messy app and make it much better. We’ll go step-by-step, from turning on GPT-5 model to using it for real coding tasks.

What is Cursor and why use ChatGPT-5 in it?

Cursor is a code editor (similar to VS Code) but with AI built in. It lets you:

Chat with AI about your code
Ask for code changes directly inside the editor
Make multi-file edits without switching tools

With ChatGPT-5 inside Cursor, you get:

Better reasoning
Smarter refactoring
Cleaner explanations

How to Turn on ChatGPT-5 in Cursor

Open any project and navigate to the right column with the chat. Then click on the word "auto" and turn off the toggle.

After that, you will see the GPT-5 model in the list

You can use two modes, "Ask" and "Agent".

Ask mode acts as an AI Assistant
Agent mode does all the hard work for you. All you need to do is look and confirm when it asks for permission to run specific commands.

Tips for Better Results

Be specific. Short, clear prompts work best.
Review everything. Don’t apply changes without reading them.
Ask for explanations. Use Chat to explain diffs in plain English.
Work in small chunks. Big changes are harder to debug.
Keep testing. Run your app after each step.
