ChatGPT is a large language model chatbot developed by OpenAI based on GPT-3.5. It has a remarkable ability to interact in conversational dialogue form and provide responses that can appear surprisingly human. Large language models perform the task of predicting the next word in a series of words.

Reinforcement Learning with Human Feedback (RLHF) is an additional layer of training that uses human feedback to help ChatGPT learn the ability to follow directions and generate responses that are satisfactory to humans.

What Does ChatGPT Mean?

ChatGPT (Chat Generative Pre-trained Transformer) is a complex machine learning model that is able to carry out natural language generation (NLG) tasks with such a high level of accuracy that the model can pass a Turing Test.

ChatGPT was trained on massive amounts of unlabeled data scraped from the internet before 2022. The model is continually being monitored and fine-tuned for specific language-oriented tasks with additional datasets labeled by humans.

Tasks ChatGPT excels at include:

  • Providing answers to questions.
  • Completing a given text or a phrase.
  • Writing fiction and non-fiction content from prompts.
  • Producing humanlike chatbot responses.
  • Generating computer code.
  • Translating text from one language to another.
  • Performing calculations.
  • Summarizing a given text.
  • Classifying text into different categories.
  • Analyzing text sentiment.
  • Generating text that summarizes data in tables and spreadsheets.
  • Responding to user input in a conversational manner.

ChatGPT is built on a large language model (LLM) called GPT-3 (Generative Pre-trained Transformer 3). A large language model is a type of deep neural network that uses billions of parameters and is trained with petabytes of data. The model was developed by OpenAI, a research firm founded by Elon Musk.

Who Built ChatGPT?

ChatGPT was created by San Francisco-based artificial intelligence company OpenAI. OpenAI Inc. is the non-profit parent company of the for-profit OpenAI LP. OpenAI is famous for its well-known DALL·E, a deep-learning model that generates images from text instructions called prompts.

The CEO is Sam Altman, who previously was president of Y Combinator. Microsoft is a partner and investor in the amount of $1 billion dollars. They jointly developed the Azure AI Platform.

Why is ChatGPT Not Working?

When you try to sign up for the AI chat service ChatGPT, an error message saying that ” ChatGPT is at capacity right now” will appear. This signifies that they are momentarily unable to add new users due to a flood of traffic.

Just like any other online service, ChatGPT requires servers to operate. In the face of high volumes of traffic, they tend to overload. For that reason alone, the ” at capacity” error occurs. Due to the high volume of users, the servers cannot process all the requests.

Most of these problems can be attributed to the fact that the server is already operating at full capacity. It’s also possible that they indicate an issue with your network connection. So, how can you easily fix this?

How Does It Work?

On the face of it, GPT-3’s technology is simple. It takes your requests, questions or prompts and quickly answers them. As you would imagine, the technology to do this is a lot more complicated than it sounds.

The model was trained using text databases from the internet. This included a whopping 570GB of data obtained from books, webtexts, Wikipedia, articles and other pieces of writing on the internet. To be even more exact, 300 billion words were fed into the system.


As a language model, it works on probability, able to guess what the next word should be in a sentence. To get to a stage where it could do this, the model went through a supervised testing stage.

Here, it was fed inputs, for example “What colour is the wood of a tree?”. The team has a correct output in mind, but that doesn’t mean it will get it right. If it gets it wrong, the team inputs the correct answer back into the system, teaching it correct answers and helping it build its knowledge.

It then goes through a second similar stage, offering multiple answers with a member of the team ranking them from best to worst, training the model on comparisons.

What sets this technology apart is that it continues to learn while guessing what the next word should be, constantly improving its understanding of prompts and questions to become the ultimate know-it-all.

How to Fix The “ChatGPT is at Capacity Right Now” Error?

If the capacity error in ChatGPT is driving you crazy, try taking it easy for a while and try these solutions to fix the “ChatGPT is at capacity right now” error:

  • Wait for a little.
  • Refresh the page.
  • Login to your ChatGPT account again.
  • Use a VPN.
  • Use ChatGPT in Incognito.
  • Try a second OpenAI account.
  • Clear your browser’s cache.
  • Use a different OpenAI API.
  • Avoid using ChatGPT during peak hours.
  • Subscribe to ChatGPT Professional.
  • Check the ChatGPT server status.
  • Use a ChatGPT alternative.

How to Register an OpenAI Account

Using the ChatGPT chatbot is fairly simple, as all you have to do is type in your text and receive the information. However, OpenAI does require an account before you can use any of its tools, so if you don’t have one, you will have to register. You have the option of choosing an easy login with a Google or Microsoft account.

Otherwise, if you have any other kind of email, you can enter it manually. After this, you must enter a phone number; however, keep in mind that you cannot use a virtual phone number (VoIP) to register for OpenAI. You will then receive a confirmation number, which you will enter on the registration page to complete the setup.

Once you see some housekeeping rules about ChatGPT, including potential errors in data, how OpenAI collects data, and how users can submit feedback, you know you have successfully registered.

How Was ChatGPT Trained?

Data scientists and machine learning engineers used semi-supervised learning to train ChatGPT. Semi-supervised learning algorithms are trained on datasets that are partially labeled; some of the data points have a label and some do not. The model uses the labeled data to predict the output of the unlabeled data.

According to OpenAI, data scientists gathered the huge amount of unlabeled data required to train the LLM by scraping the internet. They supplemented this with text sources that were either in the public domain or made available for use by researchers and possibly governments.

OpenAI has not revealed exactly how they were able to label the immensely large data sets required to fine-tune the model, but it’s known they outsourced some of the labeling and it’s likely they also took advantage of crowdsourcing platforms like Amazon’s Mechanical Turk.

Is ChatGPT Free to Use?

Yes, the basic version of ChatGPT is completely free to use. It’s not free for OpenAI to continue running it, of course. Estimates are currently that OpenAI spends around $3 million per month to continue running ChatGPT, which is around $100,000 per day. Beyond the cost of the servers themselves, some egregious information has recently come out about what else has been done to train the language model against producing offensive content.

OpenAI has also recently announced a new paid, premium version of its chatbot, called ChatGPT Professional. You can currently only join the waitlist, though, and the monthly price is unknown. The features that may be available in ChatGPT Premium include no throttling, an unlimited number of prompts, faster response, and no blackouts.

Best ChatGPT Alternatives

OpenAI’s ChatGPT is one of the most popular chatbots in the market. But of course, there are some alternatives to it, such as:

  • Chinchilla
  • Notion AI
  • Chai
  • NovelAI
  • Caktus AI
  • AI Dungeon

How Can ChatGPT be Used?

ChatGPT can write code, poems, songs, and even short stories in the style of a specific author. The expertise in following directions elevates ChatGPT from an information source to a tool that can be asked to accomplish a task.

This makes it useful for writing an essay on virtually any topic. ChatGPT can function as a tool for generating outlines for articles or even entire novels. It will provide a response for virtually any task that can be answered with written text.

Business Uses for ChatGPT

ChatGPT is being used as an augmented intelligence tool for a wide variety of business tasks. It is currently being used to:

  1. Automate the content creation process for social media posts, website articles and product descriptions.
  2. Build customer-facing conversational chatbots that are capable of going off script.
  3. Summarize and categorize customer feedback from multiple channels.
  4. Translate business reports and marketing deliverables from one language to another.
  5. Write boilerplate computer code and generic scripts.
  6. Translate the information contained in a table or spreadsheet into text.
  7. Create chatbots that support just-in-time learning for internal training programs.
  8. Write meta descriptions and suggest synonyms for SEO keywords.


As previously mentioned, ChatGPT is envisioned as a tool that the public will eventually have to pay to use. Over a million users have registered to use ChatGPT within the first five days since it was opened to the public.
