Applications and landscapes of artificial intelligence are diversifying day by day. A little over a year ago, OpenAI released ChatGPT to users. We were all shocked to see that we could complete time-consuming tasks in minutes using just a few prompts. The development of ChatGPT was not limited to text generation and continued to constantly update and develop itself. One of OpenAI's latest services is GPTs, which allows you to build your own ChatGPT.

What are GPTs?

GPTs is an AI chatbot builder tool that allows you to build your own custom ChatGPT and assign it to specific tasks. While ChatGPT is currently an effective solution for completing most repetitive tasks, you can take things a step further and build your own personal ChatGPT.

Building your own custom GPT has benefits both in daily and professional life, such as;

  • Task-focused Content Generation
  • Specific Use Case Adaptation
  • Concise and Accurate Output Generation
  • Custom Data Training
  • Streamline Workload
  • Increased Productivity

How Do GPTs Operate?

GPTs generate output using the GPT-4 large language model. The only difference between GPTs and ChatGPT-4 is that GPTs are customizable. You can create your own GPT with prompting and data training methods and take your AI chatbot experience to the next level.

What is the Difference Between ChatGPT and GPTs?

ChatGPT is an AI chatbot that generates output within the limits of its own persona with pre-trained data and parameters. If you want to use ChatGPT for specific tasks, you would have to customize it with the prompting method for each new task. However, thanks to GPTs, you can customize ChatGPT at once and use the GPT you created over and over again without additional prompting. In short, while ChatGPT has a generic output style, you can customize GPTs as you wish.

Is Custom GPTs Free?

To use OpenAI's GPTs tool, you must have a Plus or Enterprise subscription. This tool is not available for free ChatGPT users. You can activate the OpenAI Plus subscription for $20/month. Once you have the Plus subscription, you do not need to pay additional fees to build GPT or try OpenAI's GPTs.
