1.3. History of language models

History of language models

The history of language models is a fascinating record of the evolution of natural language processing technology. As computers became more powerful, language models also developed at a frightening pace.

Early language models from the 1960s and 1970s were relatively simple and relied on statistics and grammatical rules. One example is the "Markov Chain" model. With the development of neural networks in the 1980s and 1990s, language modeling became more advanced. These models, such as HMM (Hidden Markov Models) and RNN (Recurrent Neural Networks), were able to handle more complex language structures. The arrival of the era of Deep Learning made language models much more complicated and effective. LSTM (Long Short-Term Memory) and GRU (Gated Recurrent Unit) models enabled a better understanding of long-term dependencies in text.

In 2017, the Transformer architecture appeared, which revolutionized the field of natural language processing. GPT (Generative Pre-trained Transformer) models were among the first to use this architecture. They opened the way to creating advanced models such as ChatGPT.
1.2.5 ChatGPT and Subsequent Evolutions In 2020, OpenAI released the first version of ChatGPT, which was a breakthrough in the field of chatbots. Then subsequent versions appeared, such as ChatGPT-3, which were even more advanced and flexible in generating text.

The history of language models is a journey from simple statistical models to advanced architectures based on neural networks. ChatGPT is one of the most modern language models, which use these advanced technologies to generate text in an incredibly complicated and useful way. Its development is a fascinating example of progress in the field of artificial intelligence.

2.1. Getting access to ChatGPT

How to use ChatGPT? Access and interface

To start using ChatGPT, you need access to this tool. Here are the steps that will help you get access:

  1. Registration on the platform: The first step is to register on the platform that offers access to ChatGPT. This can be a website or mobile app.
  2. Creating an account: After registration, you need to create an account. This usually requires providing basic information such as email address and password.
  3. Purchasing access: Depending on the platform, access to ChatGPT may be free or paid. If it is paid, you will need to choose an appropriate subscription plan or purchase an appropriate number of tokens. The standard version 3.5 is free, but its knowledge base is limited to September 2021.
  4. Account configuration: After purchasing access, you may need additional configuration, such as setting language preferences or adjusting model parameters.

2.2. User interface vs. API

Now that you have access to ChatGPT, you need to decide how you want to integrate with it. There are two main options:

  • User interface (UI): This is an easy way to use ChatGPT. After logging into the platform, you have access to an interactive window where you can enter your questions and receive answers.
  • API (Application Programming Interface): The API is a more advanced option and is intended for developers. It gives control over ChatGPT and allows integration with your own applications. If you are a developer, you can use the API documentation to integrate ChatGPT with your own projects.

ChatGPT for beginners: how to start?

The choice between the user interface and the API depends on your needs and skills. If you are a beginner user, the user interface may be a good place to start because it is simple and intuitive. If you are a developer or want more advanced control over ChatGPT, the API may be the right option for you.

2.3. What are Prompts?

How to write good prompts?

Prompts, also called "prompts", are texts or questions that users provide to the GPT model to obtain answers or generated content. These are hints or input information that help determine the context or purpose of interaction with the model.

Examples of prompts:

"Write a short story about a space journey." "Translate the following sentence into French: 'Hello, how are you?'" "What do you think about climate change?"

In the case of the GPT model, such as ChatGPT, prompts are a key element of communication. They indicate what information or answers the user expects from the model. For example, using the prompt "Write a short story about a space journey", the user suggests to the model that they want to read a short story on this topic.

Sending appropriate prompts is important to get the desired results from the model. Well-formulated prompts help in effective communication with the model and obtaining answers or content that meet the user's expectations.

2.4. Sending text queries

Communicating with the ChatGPT model is relatively simple and involves sending it text queries. Here's how to do it:

  1. Enter your question: In the user interface or using the API, you can enter your question or content that you want ChatGPT to work with.
  2. Understanding context: The model will analyze the entered question in the context of previous questions and answers, which will allow it to better understand exactly what you mean.
  3. Waiting for an answer: After entering the question, you will receive an answer from ChatGPT. This can be text that answers your question or continues the conversation.

2.5. Interpreting responses

Interpreting the responses generated by ChatGPT is a key aspect of using this tool. Here are some tips on how to do it:

  1. Understanding context: Remember that ChatGPT's responses are generated in context. When reading the answer, it is worth analyzing whether it refers to your question or previous statements.
  2. Assessing credibility: Be careful and critical of generated content. ChatGPT generates text based on training data and is not always able to provide correct and current information.
  3. Correcting responses: If necessary, you can correct the answer or ask additional questions to get a better explanation or specific information.
  4. Ask questions clearly: The more precise your question is, the more likely you are to get an accurate answer.
  5. Practice and experimentation: Over time, you will understand how to communicate effectively with ChatGPT and how to get the desired results. Experiment and learn as you go.

2.6. How to get the best results?

To get the best results from the GPT model, in this case ChatGPT, it is worth following a few key rules:

  1. Ask clear and precise questions: The more precise your question is, the more likely you are to get an accurate answer. Avoid vague or ambiguous questions.
  2. Be patient: Sometimes the model needs several attempts to generate a response that meets your expectations. Experiment and adjust questions and parameters until you get the desired results.
  3. Control content: Responses generated by ChatGPT can be creative, but not always accurate or factually correct. Be careful and verify information, especially if you use the model for business or educational purposes.
  4. Develop the conversation gradually: Start with simple questions and gradually develop the dialogue to avoid confusion or answers that do not fit the context.
  5. Experiment: Don't be afraid to experiment with different settings and questions. This will allow you to discover new possibilities of the model.

Remember that the GPT model is a tool and does not always generate ideal answers. The key to getting the best results is understanding how it works and skillfully adapting it to your needs.
