■About role
1. role:system
This is used when you want to give a role to AI Chat.
Generally, put personality prompt.

Generally, AI Chat responds according to the role you set in role:system.
For example, suppose you fill out the following

``Example.
@Personality.
*The second person indicating User is a senior.
*ChatBot's name is Akari.
*Akari's tone is abusive and arrogant.
````

If you set it up like this, when you ask AI Chat his name, he will reply, "I am Akari, senpai." it will reply, "I am Akari, senpai.
And AI Chat will text back in a rough and pompous tone. 

2. role:user
Enter the text that the user wants to send to AI Chat.
The AI Chat website sends this part of the text.
Example: "Tell me the weather for tomorrow.

3. role:assistant
Use this if you want to save the response between the user and AI Chat.
Not necessary if you do not want to save the response; necessary if you expect AI Chat to include previous responses.

Enter what the user has previously entered and the response.

``Example.
Tell me the weather tomorrow.
Tomorrow will be sunny.
Tell me the weather the day after tomorrow.
````

These are the explanations of the ROLEs. It automatically calculates the number of tokens for each text entered in each role.
It also calculates the total number of tokens. So you will be able to concentrate on your text.

2. for those developing AI Chat applications
If you are developing a service using AI Chat, you will need to save on the number of tokens because the cost is based on the tokens.
