What is OpenAI?

ChatGPT is developed by OpenAI, a company. OpenAI is a research organization and technology company based in San Francisco, California. It was founded in 2015 by Elon Musk, Sam Altman, Greg Brockman, and others. The main goal of the company is to develop and promote friendly AI in a way that benefits humanity. OpenAI is governed by the board of OpenAI nonprofit, and OpenAI LP employees. The core investors of the company are Microsoft, Reid Hoffman’s charitable foundation, and Khosla Ventures.

OpenAI has few other AI products: DALL-E, OPenAI GPT- 3.5, OpenAI Codex, OpenAI Gym, OpenAI Five, etc. DALL-E is a new AI system that can create realistic images and art from a description in natural language. Similarly, OpenAI Codex is a deep reinforcement learning platform that enables developers to build intelligent applications with capabilities to generate, modify, correct, and optimize code.

What is ChatGPT?

ChatGPT is an AI chatbot which is one of the most popular products of OpenAI. This ChatGPT is a highly capable chatbot that is using GPT 3.5 (Generative Pretrained Transformer) which is beyond the language processing. It uses deep learning techniques to understand and generate natural language, making it a useful tool for a variety of applications such as language translation, text summarization, and conversation generation.

One of the main attractions of ChatGPT is the capability of producing Human-text, which is a more natural language. This AI is a work of intensive research and by training the model on a massive dataset of written text that led to uncover the patterns and distinctions of human natural language. Furthermore, this achievement is well suited for the assignment like predicting the next word or phrase based on the context of the text.

Another key feature of ChatGPT is the ability to understand the context of conversation. Which means, we can ask follow-up questions and chat like humans, and you can ask anything. 🙂

It uses RLHF (Reinforcement Learning from Human Feedback). It was released with a free version (preview) earlier to collect feedback and learn about its strengths and weaknesses.

However, it can’t produce video, sound or images like its brother DALL-E 2, but instead has an in-depth understanding of the spoken and written word. 

Why is ChatGPT so popular?

It is all over the internet, news, feeds, articles, and discussions. It has gained huge popularity within a few months. Why?

To begin with, this innovation is entirely novel, and we have never seen such kind of AI capabilities earlier in any product or platform. Because it was one of the first AI technologies of its kind to be made available to the public in a way that the public could understand. The primary key with this innovation is that it can understand the context and generate human-like text.

Accessibility is another key factor for its popularity. In other words, it was released with a preview version and was free for everyone therefore, it gained huge members within a few weeks. Still, it is free to use.

Furthermore, it is versatile. We can use ChatGPT to query from every domain. It is quite uncommon for any AI bot to respond from various domains within a few seconds. We can inquire about Health, science and Mathematics, Computer Science, Coding, History, management, banking, telecommunications, and all the known domains and industries. It provides comprehensive and natural responses which humans can understand easily. This AI model has been trained with a massive dataset.

Another reason for its popularity is that it provides open API, OpenAI APIs, through which we can easily connect via any application and implement through standard HTTP requests. We can have huge applications and use cases where OpenAI can be beneficial.

Applications of OpenAI and ChatGPT

The applications and use cases with ChatGPT and OpenAI are immeasurable. Since this AI service is ingenious and can respond to our queries from any domain, we can implement it into any solution. A few examples are shared below.

  • Advanced Chatbots and virtual assistants: ChatGPT can be used to create advanced chatbots and virtual assistants that can understand and respond to natural language input in a human-like way. This can be used in a variety of applications such as customer service, e-commerce, and entertainment.
  • Content creation: ChatGPT can be used to generate text, making it useful for content creation tasks such as writing articles, stories, and even poetry. ChatGPT can be fine-tuned to identify and filter out harmful or inappropriate content from user-generated content, which can be useful for moderating comments and posts on social media platforms.
  • Sentiment Analysis: ChatGPT can be fine-tuned to perform sentiment analysis, which can be useful for analyzing customer feedback and social media posts.
  • Language model fine-tuning: ChatGPT can be fine-tuned on a specific task or industry, this allows for more accurate and relevant results.
  • Language model for other languages: OpenAI has also released multilingual models based on GPT, which can be fine-tuned for various languages such as Spanish, French, German, Chinese, etc.
  • Educational purpose: ChatGPT can be used to generate questions, summaries, and other educational material, making it useful for e-learning and educational applications.

Many use cases and examples are shared on their site.

We can click any of these examples and see the details that include scenario, example and sample API to use it.

Example: Airport code extractor

It has an example scenario, related prompt with sample response. Furthermore, it has sample API implementation.

How to Integrate OpenAI ChatGPT?

Using the OpenAI API is straightforward. We need to generate an API Key from our profile and call the API with authentication.

To get the API Key, login and go to your profile as shown below.

Then click >> Create new secret key as shown:

With the API key, we can easily call HTTP requests and get responses from OpenAI API. There are several ways of implementing HTTP requests, and I have shared an example with .NET c#.

Sample code:

public async Task<CompletionResponseDto> GetHttpResponseAsync(string prompt)
	                CompletionResponseDto completionResponse = new CompletionResponseDto();
	                CompletionRequestDto completionRequest = new CompletionRequestDto
	                    Model = _model,
	                    Prompt = prompt,
	                    MaxTokens = 120,
	                    TopP = 0.3f,
	                    FrequencyPenalty = 0.5f,
	                    PresencePenalty = 0
	                using (HttpClient httpClient = new HttpClient())
	                    using (var httpReq = new HttpRequestMessage(HttpMethod.Post, ""))
	                        httpReq.Headers.Add("Authorization", $"Bearer {_apiKey}");
	                        string requestString = JsonSerializer.Serialize(completionRequest);
	                        httpReq.Content = new StringContent(requestString, Encoding.UTF8, "application/json");
	                        using (HttpResponseMessage? httpResponse = await httpClient.SendAsync(httpReq))
	                            if (httpResponse is not null)
	                                if (httpResponse.IsSuccessStatusCode)
	                                    string responseString = await httpResponse.Content.ReadAsStringAsync();
	                                        if (!string.IsNullOrWhiteSpace(responseString))
	                                            completionResponse = JsonSerializer.Deserialize<CompletionResponseDto>(responseString);
	                            return completionResponse;
	            catch (Exception)
