ChatGPT God Mode: The Secret Settings That Change Everything

Stop Using Basic ChatGPT: Here is How to Unlock 'God Mode'

BREAKING December 25, 2025 | By The Tech Mirror

Stop what you are doing.

You are likely using ChatGPT like a generic chatbot. You ask a question, you get a vanilla answer. But what if I told you there is a hidden configuration panel—a "God Mode" of sorts—that forces the AI to behave exactly how you want, 100% of the time?

It's called Custom Instructions, and it’s the difference between an AI toy and a professional assistant.

TL;DR - Why This Matters:
• Stop Repetition: Never tell ChatGPT your job title or location again.
• Better Tone: Force the AI to be concise, professional, or code-heavy.
• Instant Efficiency: Cut down your prompt engineering time by 50%.

The Setup: How to Configure Custom Instructions

Don't just read this. Open a new tab and follow these exact steps to upgrade your workflow immediately.

1. Access the Interface

Navigate to ChatGPT on your browser.

2. Locate Your Profile

Click on your Profile Icon at the bottom left corner. Select the Custom Instructions option from the menu.

3. The Control Panel

A window will pop up. This is where the magic happens. You have two distinct boxes to fill.

The Strategy: What to Type in the Boxes

Box 1: "What would you like ChatGPT to know about you?"

Do not be vague. Feed it specific data points about your profession and location. This context prevents hallucinations and irrelevant advice.

• Context: "I am a Senior Software Engineer based in India."
• Expertise: "I specialize in Python and AWS."
• Goals: "I am looking to optimize legacy code for cloud-native environments."

Box 2: "How would you like ChatGPT to respond?"

This is your style guide. If you hate fluffy intros (like "Certainly! Here is the code..."), kill them here.

• Format: "Be highly professional. No fluff. No moralizing."
• Length: "Keep responses under 200 words unless asked for a deep dive."
• Action: "Always provide a code block for technical questions."

4. Activate and Save

Toggle the enable button. Hit save. Your OpenAI experience is now permanently upgraded.

The "Bracket Hack" (Alternative Method)

Don't want to change your global settings? You can inject custom instructions on the fly using square brackets `[ ]`. This is great for temporary persona shifts.

Final Thoughts

Custom instructions are not just a feature; they are the most underutilized asset in the OpenAI ecosystem. By defining your persona and expected output format, you stop fighting the AI and start leading it.

Go customize your settings now. Your productivity will thank you.

Frequently Asked Questions

Are Custom Instructions available for free users?

Yes! OpenAI has rolled out Custom Instructions to both Free (GPT-3.5/4o-mini) and Plus users. You can access it in the settings menu regardless of your subscription tier.

Do Custom Instructions affect every new chat?

Yes. Once enabled, the "Enable for new chats" toggle ensures that every new conversation you start will inherit these instructions. Old chats will remain unaffected unless you restart them.

How do I turn off Custom Instructions?

Simply go back to the Custom Instructions menu (Profile > Custom Instructions) and toggle the "Enable for new chats" button to OFF. You do not need to delete the text in the boxes.

What are the best Custom Instructions for coding?

For developers, tell ChatGPT to: "Only output code," "Do not explain unless asked," "Use Python 3.10+ syntax," and "Add comments for complex logic." This saves significant reading time.

Can I have multiple Custom Instruction profiles?

Currently, ChatGPT only supports one set of instructions at a time. If you need to switch often, we recommend saving different instruction sets in a separate document (like Notion) and pasting them in as needed.
