Experience the Future of Communication With GPT-3: Consume GPT-3 API Through MuleSoft

Chatbots can significantly improve how we communicate and interact with technology. Explore the potential of GPT-3 and other language-generation tools.


It is a chatbot that uses the GPT-3 (Generative Pre-trained Transformer 3) language model developed by OpenAI to generate human-like responses to user input. The chatbot is designed to be able to carry on conversations with users in a natural, conversational manner, and can be used for a variety of purposes such as customer service, online support, and virtual assistance.


OpenAI offers a number of Application Programming Interfaces (APIs) that allow developers to access the company’s powerful AI models and use them in their own projects. These APIs provide access to a wide range of capabilities, including natural language processing, computer vision, and robotics.

These APIs are accessed via HTTP requests, which can be sent in a variety of programming languages, including Python, Java, and MuleSoft. It also provides client libraries for several popular programming languages to make it easy for developers to get started. Most interestingly, you can train the model on your own dataset and make it work best on a specific domain. Fine-tuning the model will make it more accurate, perform better and give you the best results.


It is a company that provides integration software for connecting applications, data, and devices. Its products include a platform for building APIs (Application Programming Interfaces) and integrations, as well as tools for managing and deploying those APIs and integrations. MuleSoft’s products are designed to help organizations connect their systems and data, enabling them to more easily share information and automate business processes.

Steps To Call GPT-3 model API in MuleSoft

  • Account:  Create an account using your email id or continue with Google or Microsoft account:

Create your account

  • Authentication: The OpenAI API uses API keys for authentication. Click API Keys to generate the API key.

API Key Generated

Do not share your API key with others, or expose it in the browser or other client-side code. In order to protect the security of your account, OpenAI may also automatically rotate any API key that we’ve found has leaked publicly. (Source: documentation)

The OpenAI API is powered by a family of models with different capabilities and price points.

  • The highly efficient GPT-3 model is categorized into four models based on the power level suitable to do their task.
text-davinci-003 Most capable GPT-3 model. Perform any task w.r.t other models with higher quality, longer output, and better instruction-following 4000 Jun-21
text-curie-001 Very capable, but faster and lower cost than Davinci. 2048 Jun-19
text-babbage-001 Very fast and lower cost, Perform straight forward task 2048 Jul-19
text-ada-001 Perform simple task 2048 Aug-19

Where GPT-3 Could Potentially Be Used

Content Creation

The API can be utilized to generate written materials and translate them from one language to another.

Software Code Generation

The API can be used to generate software code and simplify complicated code, making it more comprehensible for new developers.

Sentiment Analysis

The API can be used to determine the sentiment of text, allowing businesses and organizations to understand the public’s perception of their products, services, or brand.

Complex Computation

The API can assist in large data processing and handle complex calculations efficiently.


Like all natural language processing (NLP) systems, GPT-3 has limitations in its ability to understand and respond to user inputs. Here are a few potential limitations of GPT-3:

  1. Reliability: Chatbots may not always produce acceptable outputs and determining the cause can be difficult. Complex queries may not be understood or responded to appropriately.
  2. Interpretability: The chatbot may not recognize all variations of user input, leading to misunderstandings or inappropriate responses if not trained on diverse data.
  3. Accuracy: Chatbot, being a machine learning model, can make mistakes. Regular review and testing are needed to ensure proper functioning.
  4. Efficiency: GPT-3’s test-time sample efficiency is close to humans, but pre-training still involves a large amount of text.

Overall, GPT-3 is a useful tool that can improve communication and productivity, but it is important to be aware of its limitations and use it appropriately.


As chatbots continue to advance, they have the potential to significantly improve how we communicate and interact with technology. This is just an example of the various innovative approaches that are being developed to enhance chatbot performance and capabilities.

As we continue to explore the potential of GPT-3 and other language generation tools, it’s important that we remain authentic and responsible in our use of these tools. This means being transparent about their role in the writing process and ensuring that the resulting text is of high quality and accuracy.
