OpenAI released a Optimizing Language Model for Dialogue named ChatGPT on November 30, 2022. 

Once it was released, ChatGPT gained great attention and traffic, causing much discussion on online platforms.

What is ChatGPT?

ChatGPT (full name: Chat Generative Pre-trained Transformer), a chatbot program developed by OpenAI, USA, released on November 30, 2022. ChatGPT is an artificial intelligence technology-driven natural language processing tool that is able to carry out conversations by learning and understanding human language. It can also interact based on the context of the chat, truly chatting and communicating like a human, and can even complete tasks such as writing emails, video scripts, copywriting, translation, code, and writing papers.

How to Use ChatGPT?

1.Open chat.openai.com or Open AI playground，Register ChatGPT account

2.Verify your email address and mobile number

3.Chat GPT Login--Log in ChatGPT account (if you have an account, log in directly)

4.After successful login, find the input box at the bottom and start using

The Services of ChatGPT

ChatGPT was launched on November 30, 2022, by OpenAI's headquarters in San Francisco. The service was initially launched for free to the public, with plans to profit from the service later. By December 4, OpenAI estimated that ChatGPT had more than one million users. In January 2023, ChatGPT had more than 100 million users, making it the fastest-growing consumer app in that time frame.The service works best in English and also works in some other languages, but with mixed results. Unlike other high-profile AI advances, as of December 2022, there are no official peer-reviewed technical papers on ChatGPT.

The New York Times reported in December 2022 that the next version of GPT, GPT-4, was rumored to be available sometime in 2023. In February 2023, OpenAI launched a monthly subscription plan for U.S. users called ChatGPT Plus, which costs $20. OpenAI plans to launch a ChatGPT Pro plan for a monthly fee of 42 USD, which is gradually being rolled out to more countries, with free plans available when demand is low.

The Technical Principle of ChatGPT

ChatGPT has received significant attention due to the introduction of a new technology, RLHF (Reinforcement Learning with Human Feedback), which addresses a core problem of generative models, namely how to align the output of AI models with human common sense, perceptions, needs, and values. ChatGPT is the result of technological advances in AIGC (AI- Generated Content). The model facilitates the use of artificial intelligence for content creation and improves the efficiency and richness of content production.ChatGPT (Generative Pre-trained Transformer) is a large language model developed by OpenAI, based on the transformer architecture. The technical principle behind ChatGPT is the use of unsupervised pre-training and fine-tuning for natural language understanding and generation.

The pre-training phase involves training the model on large amounts of text data to learn the statistical patterns and relationships between words, phrases, and sentences. This is done using a self-supervised learning approach, where the model is trained to predict the next word in a sequence given the previous words. The pre-training is unsupervised because it does not require explicit human annotations or labels.

After pre-training, the model is fine-tuned on specific downstream tasks, such as question-answering, language translation, or dialogue generation. Fine-tuning involves training the model on a smaller labeled dataset specific to the task at hand, allowing the model to adapt to the nuances of the task.

The key technical innovations of GPT include the use of a transformer architecture that allows the model to attend to relevant parts of the input, the use of a masked language modeling task during pre-training to enable the model to learn bidirectional context, and the use of a novel positional encoding scheme that allows the model to capture the sequential order of the input.

Overall, the technical principle behind ChatGPT is the use of self-supervised pre-training and fine-tuning to build a powerful and general-purpose natural language understanding and generation system.

ChatGPT Price -- Is ChatGPT Free to Use?

As an AI language model, ChatGPT is not a product or service that users can directly use. However, ChatGPT's responses and interactions are available for free through various platforms and applications that have integrated the model's capabilities, such as chatbots, virtual assistants, and other AI-powered applications.

It's important to note that while accessing ChatGPT's responses may be free, some platforms or applications that use the model's capabilities may have their own pricing or subscription models. For example, a chatbot powered by ChatGPT may be free to use, but the platform that hosts the chatbot may charge businesses for access to advanced features or for increased usage limits.

In summary, ChatGPT's language capabilities are available for free through various applications, but the specific pricing and usage limitations may vary depending on the platform or application that integrates the model.

Conclusion

ChatGPT currently still interacts with text, but in addition to interacting through natural human conversation, it can also be used for relatively complex language work, including a variety of tasks such as automatic text generation, automatic Q&A, and automatic summarization.
