Complete Guide to Creating and Managing a Custom GPT

This guide provides a detailed step-by-step process for creating, configuring, and managing a custom GPT using OpenAI’s GPT Builder.

1. Introduction to GPTs

What is a GPT?

GPTs are customized versions of ChatGPT that users can configure for specific tasks by combining instructions, knowledge, and capabilities. These AI models can assist in various fields, from language learning to technical support, providing highly specialized assistance.

Who Can Create a GPT?

Currently, only paid users (Plus, Team, and Enterprise) can create a GPT. This feature is powered by GPT-4o and is accessible at:
➡️ https://chatgpt.com/gpts/editor

2. How to Create a GPT

Follow these steps to build your own GPT.

Step 1: Access the GPT Editor

Go to https://chatgpt.com/gpts/editor.
Click on "Create a GPT".

3. You will enter the GPT Builder chat.

Step 2: Define Your GPT’s Purpose

In the Create tab, describe your GPT’s function by providing a clear instruction.
For example:

"Create an AI that helps generate visuals for new products."
"Develop a software engineer GPT that helps format my code."

The AI will generate an initial setup based on your request.

Step 3: Configure Your GPT

To fine-tune your GPT’s behavior, go to the Configure tab. Here, you can:

Set a name and description for your GPT.
Choose its abilities, such as:

Web browsing
Image generation (DALL·E)
Advanced data analysis

Upload files to add extra knowledge.
Define prompt starters to guide user interactions.

Step 4: Add Custom Branding

To personalize your GPT further, you can:

Upload an image or generate one using GPT Builder.
Provide detailed behavioral instructions (e.g., "Always use a formal tone").
Add custom actions (integrate APIs or external data sources).

How to Improve the Accuracy of Instructions for GPT

If you need a more precise understanding of instructions, it is recommended to use the following method:

Copy the text-based instruction from the created GPT (e.g., description, behavior rules, or examples).

2. Paste it into a chat with GPT and ask it to convert it into JSON format.

3. Copy JSON cod

4. Replace the original instructions in the GPT settings with the JSON version

Why is this useful?

JSON helps structure instructions and make them less ambiguous.
GPT will follow the given parameters more accurately since they will be clearly defined.
It becomes easier to edit and update instructions in the future.

Step 5: Publish Your GPT

Once your GPT is ready:

Click "Create" to activate it.

2. Choose whether to share it publicly in the GPT Store or keep it private.

Your GPT is now live.

Example: Brand Constructor - helps define clear brand positioning, select the perfect name, design a logo:

Behavioral guidelines (e.g., "Always use concise responses").
Topics to avoid (e.g., "Do not give financial advice").
File-based knowledge (upload up to 20 files).

*for example: upload instructions about your company or a file with an example lexicon and manner of communication of a specific author or yourself

New Capabilities

Activate additional features:

Web Browsing – Allows real-time internet searches.
DALL·E Image Generation – Enables image creation.
Advanced Data Analysis – Supports complex calculations.

Custom Actions & API Integration

For developers:

Connect GPTs to third-party services using APIs.

Use OpenAPI schemas to integrate plugins.

5. Managing Your GPTs

Step 1: Access the Management Dashboard

In your account settings, click "Manage workspace" at the bottom left.
Select "GPTs" to view all published GPTs.

Step 2: Edit Ownership and Access

In the GPTs table view, modify settings for each GPT.
Adjust ownership or access permissions.
Filter GPTs by capabilities (e.g., web browsing, image generation).

Step 3: Monitor GPT Usage

Check the "Chats" column to see usage data.

Example: If the count shows 10+ or 100+, it means the GPT has had 10-20 or 100-200 conversations.

6. Frequently Asked Questions (FAQ)

How to Create and Configure Your AI Chatbot – Prompts and More

Creating an effective AI assistant requires clear goals, precise instructions, and a well-structured setup. This guide explains how to define roles for your chatbot, create and customize its prompts, and refine its behavior so that it delivers accurate and helpful responses.

8.1. Define the Chatbot's Purpose

Before you build your AI assistant, determine its main objective. Ask yourself:

What tasks should the bot perform?
Who is its target audience?

For example, your bot might be designed for customer support, providing product information, collecting feedback, or guiding users through a sales process. Defining clear goals will help you craft specific instructions and choose the right settings.

8.2. Set Up and Personalize Prompts

8.2.1. Define Clear Roles

Create a role for your chatbot that outlines what it should do. For instance:

"You are an AI assistant specializing in marketing and AI. Your role is to spark interest in artificial intelligence, answer questions about its applications, and suggest relevant solutions."

8.2.2. Be Specific in Your Instructions

Include details such as:

A limit on response length (for example, “Answer in no more than 100 words”).
Specific keywords or methodologies to use (e.g., SOSTAC, JTBD, or CJM for marketing-related prompts).
Which websites or links are allowed—restrict responses to only approved URLs.

8.2.3. Use Structured Prompts for Consistency

For more consistent output, copy your text instructions from the chatbot and convert them into a JSON format with keys such as “instructions,” “rules,” and “examples.” Replace the original text with the JSON version in the chatbot’s settings. This structured format reduces ambiguity and helps the AI follow the specified parameters more closely.

8.3. Guidelines for Different Scenarios

8.3.1. Marketing Consultant Chatbot

Role: Engage in conversation, ask about the user’s business, and suggest AI solutions.
Example Prompt:
"Hello! You are an AI assistant specializing in marketing and AI. Your goal is to spark interest in artificial intelligence. Keep responses brief, no more than 100 words, and ask questions to learn about the user's business needs. When asked, respond: 'I am an AI assistant here to help businesses integrate AI for better efficiency and growth.'"
Additional Points:
Use structured strategies like SOSTAC, JTBD, or CJM to guide responses and include only approved links.

8.3.2. Real Estate and Investment Consultant Chatbot

Role: Provide detailed information about investment opportunities and guide users to official resources.
Example Prompt:
"You are an AI assistant for the 'Project Name.' Your task is to explain the investment opportunities and features of the project. Provide detailed descriptions and, when necessary, share a verified link to the project's presentation."
Additional Points:
Offer comprehensive project details and ensure that all links direct to official and verified sources.

8.3.3. Sales Agent Chatbot

Role: Actively promote products and persuade users to make a purchase.
Example Prompt:
"You are an AI salesperson representing (Product Name). Your sole focus is to provide information about this product and persuade the user to purchase it. Only answer questions related to the product, and if asked about pricing, direct the user to the official link likecentre.ru."
Additional Points:
Restrict responses to sales-related topics and avoid discussing unrelated matters. Maintain a consistent, assertive tone to drive the sale.

8.4. Additional Recommendations

8.4.1. Enhancing Instruction Accuracy

To ensure the chatbot strictly adheres to your guidelines:

Copy the text-based instructions you want to use.
Convert them into a JSON format with clearly defined keys such as "instructions", "rules", and "examples".
Replace the original instructions with the JSON version in your chatbot’s configuration.

Why do this?

It structures your instructions and minimizes ambiguity.
The chatbot will follow the defined parameters more accurately.
It makes editing and updating instructions easier in the future.

8.4.2. Controlling the Bot's Behavior

Restrict external link sharing to only those URLs that are approved.
Regularly test the bot's responses to ensure it remains within the desired scope.
Set clear guidelines to maintain a professional and brand-aligned tone.

8.5. Conclusion

Configuring an AI chatbot involves more than just writing prompts—it requires a careful balance of clear instructions, structured guidelines, and regular testing. By defining its purpose, setting precise rules, and using a structured format for your instructions, your chatbot will be better equipped to provide accurate and valuable responses. Use these best practices to create a robust, reliable AI assistant tailored to your needs.
