1. What is the ChatGPT API?

1-1. What is ChatGPT?
ChatGPT is a highly advanced language model developed by the non-profit organization OpenAI. This model utilizes artificial intelligence to communicate with users in a chat format. ChatGPT primarily learns from a vast amount of text data available on the internet and is characterized by its ability to generate natural sentences that resemble human writing. Depending on the instructions provided (referred to as prompts), ChatGPT can engage in conversations like a human, create emails, blogs, and scenarios, generate ideas, and summarize long texts. It can also be utilized for translation and annotation tasks.

1-2. What is an API?
API stands for Application Programming Interface, which serves as a gateway for sharing data and functions between software applications and enabling them to work together. APIs provide the rules and protocols for applications to interact with each other, allowing developers to share and integrate information across different systems and platforms. Among APIs, those provided over the internet are specifically referred to as Web APIs.
Web APIs transmit data via HTTP (Hypertext Transfer Protocol). Generally, Web APIs are used to exchange data between clients and servers. A Web API receives HTTP requests from clients and returns HTTP responses. Requests include HTTP methods (such as GET, POST, PUT, DELETE) and endpoints (URLs), while responses contain data and status codes.
In information transmission and reception, data formats such as JSON (JavaScript Object Notation) and XML (eXtensible Markup Language) are commonly used. JSON is particularly human-readable and easy for machines to parse, which is why it is adopted by many Web APIs.
In many cases, access to the Web API is controlled using authentication tokens or API keys, allowing only authorized programs to access it. Additionally, data communication is generally encrypted using HTTPS, so third parties cannot read the contents of the communication.
Many services available on the internet provide Web APIs. For example, social media platforms (Facebook, X), cloud services (AWS, Azure), payment processors (PayPal, Stripe), and mapping services (Google Maps) offer Web APIs, allowing developers to use these APIs to extend their applications.
1-3. What is the ChatGPT API?
OpenAI offers various Web APIs for text generation, image recognition/generation, and speech recognition/generation. These Web APIs are collectively referred to as the OpenAI API. Among them, the Web API specifically for text generation is called the ChatGPT API. The ChatGPT API allows you to choose from different GPT models, including GPT-4 and GPT-3.5. Additionally, when using the API, you can access preview versions of the models, allowing you to try out the latest models like GPT-4 Turbo early. For more information about GPT-4 Turbo, please see the blog post below.

By utilizing the Retrieval feature of Assistants, you can provide reference files, allowing you to combine the knowledge built into ChatGPT with external knowledge to generate responses. Simply by providing your company's product or service FAQ documents, you can create a unique ChatGPT for your company.
2-2. Writing, Summarizing, and Editing
In document creation, it is possible to generate natural text in response to given texts or questions. For example, it can be utilized in various situations such as writing blog articles or creating reports. The summarization feature allows for condensing long texts into shorter versions. This is helpful when processing large amounts of information efficiently. For instance, it can be used for summarizing news articles or compiling meeting minutes. The proofreading feature can correct grammatical and expression errors in the provided text. This is beneficial for improving the quality of writing and supporting foreign language learning. For example, it can be used for proofreading English texts or editing essays.
2-3. Language Translation
By specifying the source text and the target language for translation, the ChatGPT API can perform translations. There is no need to specify the source language, as it automatically detects the language of the source text. The training data used in the development of ChatGPT includes multilingual data, but since the majority of the data is in English, ChatGPT excels at automatic translation into English, particularly in terms of expressiveness.
2-4. Email and Document Creation, Summarization, and Editing
By utilizing the ChatGPT API, you can implement functions such as creating, summarizing, and proofreading emails and other documents. For example, it can be used in various situations such as drafting important emails, creating reports, and processing long texts that need summarization. It also has a proofreading function that can correct grammatical and expression errors in emails.
2-5. Information Retrieval
ChatGPT primarily learns from data available on the web and can be used to search for various information. The most recent date of the training data for the preview version of ChatGPT, GPT-4 (gpt-4-1106-preview), is April 2023. It cannot search for the latest data after this date or for non-public data such as internal documents. By using the aforementioned Assistants API, you can provide additional information to ChatGPT, making it possible to search for the latest data and non-public data as well.
2-6. Transcription of Meetings and Creation of Minutes
The OpenAI API provides a speech recognition feature called Whisper. It can recognize speech with high accuracy not only in English but also in Japanese. There is no need to specify the language in advance as it automatically recognizes the language. However, it is important to note that it cannot recognize the speaker.
2-7. Programming Code Creation and Modification
ChatGPT has also learned programming code. It has extensive knowledge of widely used programming languages such as Python, JavaScript, and C#, allowing it to generate programming code simply by instructing it in human language about what you want to implement. It is also well-versed in best practices for programming, providing valuable advice during design and testing. You can also pass existing code and ask for explanations.
2-8. Debug Verification, Specification Confirmation
During debugging, you can obtain explanations about the details of issues by providing error messages. It is also possible to pass programming code to have the suspected areas pointed out or to receive suggestions for fixes. You can create code samples from specifications, or conversely, create test code.
2-9. Manual Creation
You can prepare the outline of the manual and have ChatGPT generate the text. While it is possible to generate long texts all at once, generating them by chapter or paragraph tends to improve accuracy. If you have past manuals, you can also align the style and expressions by providing that data.
