Introduction

Hello!
This article is about the topical AI service ChatGPT. It is no exaggeration to say that there is no day when we do not hear about it in the daily news.

What is ChatGPT

ChatGPT is a chat service that can generate natural sentences developed by OpenAI. AI specialized in natural language processing can be used for various purposes such as text generation, question answering, sentence summarization, language translation, etc.

GPT stands for "Generative Pretrained Transformer" and refers to a neural network model for processing natural language using deep learning architecture.

ChatGPT learns a huge amount of text data and accumulates "knowledge" as artificial intelligence. This allows you to generate responses to questions and conversations in natural language, as if they were written by a human.

OpenAI, which created ChatGPT, is an artificial intelligence research institute established in 2015, with Elon Mask and Sam Altman among its founding members. The company develops and researches artificial intelligence technology and publishes its results as open source so that researchers and developers around the world can use it.

ChatGPT is the latest achievement of natural language processing technology developed by the company, and its innovative features have become a hot topic. After the launch of ChatGPT, the company's valuation also rose to US$29 billion, more than doubling from US$14 billion in 2021.

The number of registered users surpassed 100 million in just two months, and is said to have achieved the fastest growth ever. This also shows how fast this speed was.

What you can do with ChatGPT

From here, I will explain what you can do with ChatGPT.

① Text generation
You can generate sentences by entering simple instructions. Examples of use include the automatic generation of novels and stories, the generation of product descriptions, and blog posts. It is also possible to describe functions of spreadsheet software such as Excel, and programming languages such as HTML and Python.

② Answering questions
When you enter a question, a sentence is generated in the form of an "answer". For example, if you type in "Tell me a good yakitori restaurant in Tokyo", it will answer in very fluent Japanese. ChatGPT enables chatbots and voice assistants to interact more naturally.

③Sentence summary
Since long sentences can be shortened, it can be used for news articles, automatic summaries of blog articles, summaries of research papers, summaries of books, etc.

 ④ Language translation
It is trained for multilingual translation and can translate between various languages, so it can be used for cross-cultural exchange and international business.

Usage

Anyone can use ChatGPT for free as long as they create an account (*Paid plans also exist).

<How to open an account>

① Access the official OpenAI website (https://openai.com/).
②Click the "Try ChatGPT" button in ChatGPT.
③ Click the “Sign up” button in the center of the screen.
④ After transitioning to the “Create your account” page, create an account.
⑤ After entering the necessary information, account opening is completed.

<How to use>
Once you have created an account, there is a place where you can enter text at the bottom of the page. If you type in what you want to do or a question, the answer or the contents of the generated text will appear as a response.

Examples in Japan

ChatGPT is already making its mark in the business world. Below are some examples from Japan.

・Service that enables ChatGPT on LINE
ChatGPT is a service that can be used by creating an account with a web browser, but products aimed at improving convenience have also appeared. That is the collaboration with services such as LINE and Slack that have many users.
In the future, it is thought that various new businesses will increase the number of new businesses that can benefit from innovation by devising interfaces in this way so that even people who do not interact with the IT field on a daily basis can benefit from innovation.

・ A service that moves avatars in conjunction with ChatGPT
Until now, ChatGPT was only able to exchange text, but an increasing number of companies are providing services that make the user experience richer by incorporating animations and avatars.

As a result, it is expected to be applied in various fields, and it is expected that there will be many initiatives such as online customer service and virtual YouTuber fields in the future.

・Service that enables voice calls with ChatGPT
This is another example of creating value by adding a voice call interface to ChatGPT.
It is thought that automation and labor saving can be achieved in the area of communication with people, such as making the content of voice guidance in call centers more human.

Products that make effective use of OpenAI's API are likely to be released one after another in the future.

important point

Natural language generation technology is attracting particular attention among artificial intelligence technologies. However, on the other hand, some researchers and civil society have pointed out some dangers.
The following are points to note when using natural language generation technology.

(1) Dissemination of false information
Sentences using natural language generation technology may contain a mixture of true information and disinformation. In particular, since it is possible to generate sentences that are biased toward content that emphasizes a specific position or opinion, it may lead to the spread of biased reporting and fake news.

②Acquisition of personal information
Applications and websites that use natural language generation technology may collect information entered by users. Therefore, personal information may be collected illegally.

(3) Infringement of the user's privacy
Since natural language generation technology involves communication with humans, it is necessary to interact with users. Recording and analyzing a user's behavior may lead to an invasion of privacy.

④ Disturbance of public order
Using natural language generation technology to generate socially problematic expressions and violent language may disrupt public order.

In this way, when using natural language generation technology, it is necessary for users, businesses, and researchers to give due consideration. In addition, users are required to be aware of false information and personal information issues and to check information regarding personal information protection.

On the other hand, business operators and researchers are required to create rules to prevent the creation of expressions that disturb public order and violent language, and to focus on protecting the privacy of users.

Future prospects

On March 14, 2023, OpenAI released GPT-4. ChatGPT was a chat service equipped with GPT-3.5, but with the release of GPT-4, more advanced support can be expected.

In the field of ChatGPT, if you subscribe to the paid service "ChatGPT Plus", you can use ChatGPT with GPT-4 installed. By the way, ChatGPT Plus was originally released on February 1, 2023 with the following benefits.

① Normal access is possible even during peak hours
(2) Faster response is possible
(3) New functions and functional improvements can be used in advance

ChatGPT is basically a service that can be used free of charge, but due to the rapid increase in the number of users after its release, the site has become unusable due to problems such as the input screen not being displayed, and there being no response even when posting text on ChatGPT. load was occurring.

Against this background, ChatGPT Plas has emerged as a subscription service that allows subscribers to use ChatGPT preferentially. This time, with the benefit of (3) above, it is now possible to use ChatGPT with GPT-4 installed in advance.

The clear difference between the free version and ChatGPT Plus features has not yet been clarified, so we are looking forward to future information.

Summary

ChatGPT is one of the large-scale language models that can be used for various natural language processing tasks, and is expected to be used in fields such as text generation, question answering, sentence summarization, and language translation.

It can also be said that ChatGPT plays an important role in the current progress of AI technology, as future developments through these examples are also suggested.
