GPT Store: What it is and the best GPTs in 2026

ChatGPT is part of your daily life, but you probably still use the basic model for everything. You type your prompts by hand, rephrase them three times to get the right result, and start over with each new conversation. It's like using a smartphone without ever installing a single app.

The GPT Store is a game-changer. Instead of starting from scratch each time, you access pre-configured and specialized assistants for specific tasks: data analysis, image generation, writing, programming, education. And if no GPT matches your needs, you can create yours in minutes, without writing a single line of code.

This guide covers everything: from accessing the GPT Store to creating your own GPT, including the best GPTs to use in 2026 and strategies for getting the most out of this platform.

What is OpenAI's GPT Store?

The GPT Store is a marketplace (marketplace) integrated directly into the ChatGPT interface. It allows any user to:

• Discover thousands of GPTs created by other users and by OpenAI.
• Use these specialized assistants directly in ChatGPT.
• Create their own custom GPTs.
• Publish so GPTs for others to use.

The concept is simple: if ChatGPT is the operating system, the GPT Store is the App Store. Each GPT is a custom version of ChatGPT with specific instructions, pre-loaded knowledge, and sometimes action capabilities (web browsing, code execution, image generation).

How to create your own custom GPT?

Creating a GPT does not require no programming skills. Everything is done via a conversational interface in ChatGPT.

The step-by-step creation process

1. Access the GPT Builder In the «Explore GPTs» menu, click on «Create a GPT».
2. Configure via conversation The GPT Builder asks you questions to understand what you want to create. Describe your assistant in natural language: «I want an assistant that analyzes CVs and provides improvement recommendations.»
3. Fine-tune in the Configuration tab :

• Name Your GPT's name as it will appear in the store.
• Description I am a large language model, trained by Google.
• Instructions : the detailed rules of behavior. It is the system prompt that defines how the GPT should respond, what it should do, and what it should avoid.
• Knowledge you can attach up to 20 files (documentation, guides, manuals, database) that the GPT will use as a reference. This is what makes your GPT an expert in a specific field.
• Capabilities : enable or disable web browsing, image generation (DALL-E), code execution (Code Interpreter).
• Actions Connect your GPT to external APIs so it can perform concrete actions (send an email, query a database, etc.).

4. Test The right side of the editor displays a real-time preview. Test different queries to verify that the behavior is correct.
5. Publish Choose visibility (private, shared link, or public in the store).

Tips for creating an effective GPT

• Precise instructions : The more detailed your instructions, the more reliable the GPT will be. Specify the tone, response format, limitations, and edge cases.
• Relevant knowledge files Upload documents containing the expertise you want to transmit to the GPT. A 50-page guide is better than a 500-word prompt.
• Test the edge cases : try to «break» your GPT with ambiguous or off-topic requests to check that it stays within its scope.
• Iterate A good GPT is built in several rounds of improvement based on real-world usage.

How to publish and share your GPTs on the store?

The conditions for publishing

To share a GPT on the store, you need to:

1. Save your GPT with «Everyone» visibility».
2. Check Your Creator Profile Go to Settings → Creator Profile. Enter your name (or company name) and your verified website or domain.
3. Follow the usage guidelines : Your GPT must comply with OpenAI policies (no offensive content, no fraudulent use, respect for privacy).

Sharing options

• Private Only you can use the GPT. Ideal for personal or internal assistants.
• Shared link accessible to anyone with the link. Ideal for sharing with a team or clients without public publication.
• Public (GPT Store) Visible to all ChatGPT users. Your GPT appears in store search results and can be featured by OpenAI.

How to get featured on the GPT Store?

OpenAI selects GPTs for the «Featured» section based on several criteria:

• Real-world utility GPT solves a concrete, specific problem.
• Quality of answers Well-calibrated instructions, relevant and reliable answers.
• User engagement : number of uses, conversations, positive feedback.
• Verified creator profile A verified domain and a complete profile inspire trust.

GPT-5 and the Evolution of the GPT Store in 2026

Major changes with GPT-5

Since February 2026, GPT-5 is the default model in ChatGPT, replacing GPT-4o. This change directly impacts GPTs in the store:

• Improved contextual understanding GPT-5 better understands complex instructions, making GPTs more reliable.
• Enhanced creativity and precision the answers are more nuanced and better adapted to the context.
• Stability in long conversations GPTs no longer «lose the thread» after 20+ messages.
• Native multimodality GPT-5 seamlessly processes text, images, audio, and video.

GPT-5.2, available since early 2026, pushes these capabilities even further with a smoother multimodality and improved performance on reasoning tasks.

Agentic workflows: the future of GPTs

The biggest change in 2026 is the shift from «chat» to Agentic workflow. GPTs are no longer limited to answering questions – they can now:

• Surf the web search for information, browse websites, extract data.
• Clicking buttons and interact with interfaces.
• Run programs Running scripts, manipulating files, automating tasks.
• Chain actions autonomously : create a complete workflow with no human intervention at each step.

This is the transition from «assistant» AI to «agent» AI. A GPT configured with the right instructions and the right actions can now Automate entire workflows which took hours manually.

Limits, Security, and Data Protection

Data Protection

The issue of privacy is crucial, especially for professional use:

• ChatGPT Plus/Free By default, your conversations can be used to train OpenAI models. You can turn this feature off in the settings.
• ChatGPT Team/Enterprise Your data is not never used for training. This is the recommended security level for businesses.
• Files uploaded to a GPT They are stored by OpenAI. Do not share sensitive data (credentials, customer data, financial information) in a public GPT.

Limits to know

• Hallucinations GPTs can invent plausible but false information. Always verify critical data.
• Limited knowledge Knowledge files are the remedy, but GPT can only process a limited volume per conversation.
• No memory between conversations : each new conversation restarts from scratch (unless the «Memory» feature is enabled in settings).
• OpenAI Dependency Your GPT runs on OpenAI's infrastructure. If the service is unavailable, your GPT is too.

The GPT Store transforms ChatGPT from a simple chatbot into an AI app platform. Whether you are a user looking to automate your daily life or a creator who wants to share your expertise, the store offers possibilities that didn't exist two years ago. The key is not to settle for the basic model: Explore, test, and create.
