Mastering ChatGPT Plugins & Custom GPTs

Your Comprehensive Guide to Designing a ChatGPT App with ChatGPT Plugins


How can I create a Plugin for ChatGPT?

If you are an avid chat openai api user and were searching for best chat gpt plugins, you may have discovered from openai chatgpt plugins website that creating a Plugin for ChatGPT is no longer possible. OpenAI has shifted its focus from Plugins to enabling developers to create Actions within a GPT. 

Although the plugin finder is still available in the ChatGPT dashboard, OpenAI has ceased accepting new ChatGPT plugins, transitioning towards a model where developers can create Custom GPTs and enhance GPT’s capabilities by creating Actions within the framework itself. 

Plugins for ChatGPT were extensions that allowed the AI to interact with external data, services, and APIs, enhancing its capabilities beyond its built-in knowledge and functionalities. These plugins enabled ChatGPT to perform a wide range of tasks, from fetching real-time information from the web to integrating with third-party services for more dynamic and interactive responses. 

Note that use of plugins and ‘Exploring GPTs’ is not available under chatgpt free version.

What is the Difference between a Plugin for ChatGPT and an Action?

A Custom GPT is a tailored version of ChatGPT, configured for specific tasks or knowledge domains, enhancing its responses based on predefined data or parameters. An Action, however, is a specific functionality embedded within a GPT, enabling it to perform defined tasks, like accessing external APIs or executing commands, as part of its interaction flow. Actions represent discrete operations within the broader capabilities of a Custom GPT. 

Think of a Custom GPT as a personalized robot that you’ve taught to know a lot about a specific topic or to do a particular job. An Action, on the other hand, is like a special tool or skill you give to this robot, allowing it to do a specific task, such as looking up the weather or ordering pizza, as part of its conversation with you. 

Can I create a Custom GPT without an Action?

You can create a Custom GPT tailored to specific topics or tasks without necessarily incorporating an Action. Actions are optional enhancements that enable specific functionalities, like accessing external data, but are not a requirement for customizing a GPT’s knowledge base or conversational abilities.

Setting up a Custom GPT without an Action, a person might simply guide the GPT to adopt a specific perspective or knowledge area, like “think like a historian” or “focus on marine biology,” shaping its responses accordingly without integrating external functionalities.

In setting up a Custom GPT without an Action, one might also tailor conversation styles, set specific tones or language use, instruct it to simulate certain expertise levels, or embed a unique personality or character traits, enriching the interaction experience. 

When setting up a Custom GPT, users have creatively instructed it to adopt roles like a “virtual friend” or “advice giver,” aiming to simulate more personal or engaging interactions. However, it’s crucial to approach these customizations responsibly, as seen with platforms like Janitor.ai, where ethical considerations and the intended use of GPT come into play.

Adding Action to your Custom GPT

Adding an Action to your Custom GPT introduces dynamic capabilities, such as real-time data fetching or interaction with web services, broadening the scope of tasks your GPT can perform beyond its pre-configured knowledge and conversational settings. This allows for more interactive and up-to-date responses, providing a richer user experience.

ChatGPT Plugins

For example, as well as the Custom GPT having the default ability to query Bing with ‘Web Browsing’ or option to use chatgpt code interpreter, you could also give your Custom GPT an ‘Action’ ability to access a news API to broaden its ability to access historical knowledge.

Why would I create a Custom GPT?


Creating a Custom GPT can offer numerous benefits for your brand or company, beyond the potential financial incentives of commissions from OpenAI for usage. While it’s true that using APILayer’s APIs might incur costs after a certain number of calls, the strategic deployment of a Custom GPT can bring substantial value to your business. Here are some compelling reasons:

  1. Enhanced Customer Engagement: A Custom GPT can interact with your customers in a personalized and engaging manner, providing them with tailored information, support, and services. This level of interaction can significantly improve customer satisfaction and loyalty.
  2. Brand Differentiation: Deploying a Custom GPT with unique capabilities or personality can set your brand apart from competitors. It demonstrates innovation and commitment to providing value-added services to your customers.
  3. Operational Efficiency: Automating certain customer interactions, information dissemination, or even internal tasks with a Custom GPT can streamline operations, reduce workload on human staff, and lead to faster response times.
  4. Data Insights: Interactions facilitated by a Custom GPT can generate valuable data on customer preferences, common inquiries, and feedback. This data can be analyzed to improve products, services, and customer experiences.
  5. Innovative Marketing: A Custom GPT can be a novel marketing tool, engaging potential customers through interactive content, quizzes, personalized recommendations, or even storytelling that aligns with your brand narrative.
  6. Educational Tool: For brands focused on education or knowledge dissemination, a Custom GPT can serve as an interactive learning assistant, providing explanations, supplementary information, and learning resources in an accessible format.
  7. Community Building: A Custom GPT can foster community engagement by moderating discussions, answering community questions, and facilitating interactions in online forums or social media platforms, helping to build a vibrant brand community.

While considering the development of a Custom GPT, it’s important to weigh the potential costs of API usage against the anticipated benefits and possible future commissions from OpenAI. The strategic use of a Custom GPT can lead to improved customer engagement, operational efficiencies, and innovative ways to promote and differentiate your brand.
