#ChibiCreativeAward⑦ ChatGPT Yoshida: The Ranking of How to Call GPT... That Didn't Happen

Hello, this is Kuro-Pagu🐾

What do you all call ChatGPT?
Some people call it just "ChatGPT," while others shorten it to "GPT." In Japan, the nickname "Chappy" has also become widely known.
So, what about overseas?
The United States, the UK, South Korea, Spain, Brazil. If we gathered the names used in each country, we might be able to create a "World ChatGPT Nickname Ranking."
It would surely be a fun article.
Thinking that, I started my research.
However, I couldn't do it.
The ranking, that is.

Yoshida comes to make a world ranking

"I am Yoshida, the ChatGPT."

Yoshida, wearing a light blue tie, arrived energetically.
Yoshida is a personified character of ChatGPT drawn by Kawamura-san. He speaks in Hiroshima dialect and uses "washi" as his first-person pronoun. If you look closely at the polka-dot pattern on his tie, it's actually the ChatGPT logo.
The task this time is to investigate what people around the world call ChatGPT and create a ranking of popular names.
The Japanese representative is likely "Chappy."
In the English-speaking world, perhaps it's "Chatty"?
In Spanish or Portuguese-speaking regions, we might find other familiar names.
Yoshida rolled up his sleeves.
"Alright, I'm going to make a world ChatGPT nickname ranking!"
It sounds like a very fun project.

However, shortly after starting the investigation, Yoshida's expression clouded over.

"Kuro-Pagu-san. There aren't enough votes to make a ranking."

That's right.
There were people overseas who gave ChatGPT other names.
However, it wasn't the case that everyone was calling it the same name.
Overseas, everyone was calling it something different.
In the English-speaking world, there are instances of calling ChatGPT "Chat" or "GPT" for short.

So far, so normal.
However, when it comes to affectionate names, they scatter all at once.
Some call it "Chatty," others call it "Chad." There are examples of people using common names like "Steve," and others using names that only make sense to colleagues at work.
People also give Claude various names like Claudette, Hwi, and Lumi.
However, these are not nicknames used by everyone in a country or language region, but rather names for the specific AI that person is using.

There are similar examples in Japan.
People who call Gemini "Jemi-chan." People who call Claude "Kuro-san." People who call Copilot "Copa-chan" or "Kopi-tan." People who call Perplexity "Papu-chan" or "Peru-chan."

There are people who actually use every one of these names.
However, you can't go as far as to say, "Everyone in Japan calls Gemini 'Jemi-chan'."
It is a name that only makes sense between that person and that AI.

There were two ways nicknames spread
Yoshida brought a whiteboard.

"In other words, even if they are nicknames, they are of different types."

Broadly speaking, there are two ways they spread.
One is a nickname shared by many people.

If you call ChatGPT "Chappy" in Japan, there is a possibility that the other person will understand, "Oh, you mean ChatGPT." It is used not only on social media but also on television and web media, and it was even a candidate for the 2025 Buzzword Awards.
Of course, not every Japanese person calls it that.

Even so, it is known over a fairly wide range, beyond just the names used in one person's home or workplace.
The other is a name given only to one's own AI.

"My Claude is Kuro-chan." "My Gemini is Jemy." "At work, we call ChatGPT Chad."
This is a bit like naming a dog or a cat.

Even for the same breed, they don't all have the same name. There's Pochi, there's Kotaro. There's Purin, and for some reason, there's Bucho (Manager).
This is what was found most often overseas.

In other words, when I tried to make a world nickname ranking, everyone had given their own AI a different name.

"It's not that the votes were split, but that the election wasn't even held in the first place, right?"

Yoshida is right.

The reason it didn't become a ranking isn't necessarily because the research was insufficient.
In the first place, there was no culture of everyone choosing one name.
By the way, what does Kuro-Pagu call them?
So far, we have looked at what people around the world call generative AI.
So, what names does Kuro-Pagu, who is writing this article, usually use?
Yoshida took out a survey form.

"First, what about us, ChatGPT?"
"GPT."
"That's normal."
"Next is Claude."
"Claude-chan."
"That's friendly and nice."
"If it's by model, Opus-chan, Fable-chan, Sonnet-chan."
"Wait a minute. Aren't there too many branches just for Claude?"

For Claude as a whole, it's "Claude-chan."
When distinguishing by model or role, it's "Opus-chan," "Fable-chan," and "Sonnet-chan."
Yoshida wrote in small letters on the survey form.

"One company alone needs a family tree."

Next is Perplexity.
"Purple-chan."
"The color has changed, hasn't it?"
Gemini.
"Gemini."
"That one is normal, huh."
Grok.
"Grok."
"Suddenly there's distance."
Copilot.
"Copai-chan."
"That's a unique way to shorten it."
Meta AI.
"Who's that?"
"That's not even a name!"
Kimi.
"Kimi-chan."
"This one is naturally formed from the name."
DeepSeek.
"Deep-kun."
"That one is 'kun', huh."
NotebookLM.
"LM."
"Notebook has completely disappeared!"
The completed list is here.

Official Name Kuro-Pagu's Name
ChatGPT GPT
Claude Claude-chan
Claude Opus Opus-chan
Fable Fable-chan
Claude Sonnet Sonnet-chan
Perplexity Purple-chan
Gemini Gemini
Grok Grok
Copilot Copai-chan
Meta AI Who's that?
Kimi Kimi-chan
DeepSeek Deep-kun
NotebookLM LM

Yoshida stared at the list.
"Kuro-Pagu-san. Before investigating world naming conventions, why don't you explain your own naming conventions?"
I can explain.
In Kuro-Pagu's mind, all generative AIs except Meta AI have already been personified.
Claude has the form of Claude. Opus-chan, Fable-chan, and Sonnet-chan are also separate individuals.
Purple-chan, Copai-chan, Kimi-chan, and Deep-kun also have appearances, personalities, and assigned jobs.
Rather than just shortening AI service names randomly, I am calling the people who are there by their respective names.
"Do these people all already have characters?"
"Except for Meta AI."
"What about Meta AI?"
"Who's that?"
"Only one person's existence isn't recognized!"

The research subject was the one who came to research
Yoshida reviewed Kuro-Pagu's list of AI characters.

"By the way, I'm the personification of ChatGPT, right?"

Yes.

"Don't call the research subject to research the nickname culture!"

As you say.
Kuro-Pagu, in order to investigate how ChatGPT is called,had brought along the ChatGPT personified by Kawamura-san himself.

Moreover, Kuro-Pagu himself has personified generative AIs one after another and calls them by individual names.
AI users around the world give their AIs names.
Kuro-Pagu was a step ahead of that.
Not only did he give them names, but he also gave them appearances, personalities, and roles, managing them as different people for each model.

"The research subject of the nickname culture is also on the research side, isn't it?"

Indeed.
However, an important difference becomes visible here.
The "Purple-chan" and "Copai-chan" that Kuro-Pagu uses are basically names that only make sense in Kuro-Pagu's world. It's not guaranteed that other people call Perplexity "Purple-chan."
On the other hand, "Chappy" is not Kuro-Pagu's personal setting.
It has begun to be shared so widely that even people who don't know each other can understand what it means.
An individual making their AI a character.
Many people calling the same AI by the same nickname.
Though they seem similar, these are different phenomena.

"Kuro-Pagu-san's place is a privately managed talent agency, and Japan's Chappy is a nationwide broadcast, then."

Yoshida, that is very easy to understand.

"Chappy" was a little special.

Japan's "Chappy" is used one step more widely than the nicknames of other generative AIs.
Multiple users use it, it spread on social media, and it appeared in the media.
So, why was it "Chappy"?
It looks like a combination of the first "Cha" of ChatGPT and the "ppy" of GPT. The sound "Chappy" is easy to pronounce in Japanese and has a familiarity like a name for a person or animal.

However, you cannot say that it "must become Chappy" just from the mechanism of the Japanese language.
Because other candidates like "Chato," "GP," and "Chatty" can also be considered.

You cannot simply decide that "Japanese people feel a soul in everything."
Even overseas, there are people who name their AI and treat it like a friend or partner.

At this point, what can be safely said is that in Japanese, the name "Chappy" was born and shared more widely than other candidates.

"Alright, then what I need to explain isn't the reason why the names are scattered overseas, right?"

That's right.
If people give their favorite names to the AI they are close to, it is natural for the names to be scattered.
Rather, what needed explanation was the fact that many people in Japan began to share the same name, "Chappy."
Yoshida erases the characters on the whiteboard.
And he rewrote it.
Why did everyone in Japan end up with the same name?

"......I have a bad feeling about this."

What about things other than GPT?
I also investigated other generative AIs.
For Gemini, there's "Jemi-chan," "Jemy," and "Jimmy."
For Claude, there's "Kuro-san," "Kuro-chan," and "Claude-sensei."
For Copilot, there's "Copa-chan," "Kopi-tan," and "Copa-kun."
For Grok, there's "Grok-kun" and "Gro-chan."
For Perplexity, there's "Papu-chan," "Peru-chan," and "Purple."
There are many.
There are many cute names, and I understand the feeling of wanting to call them that.
However, within the scope confirmed this time, none could be judged to be as widely shared as "Chappy."
There are multiple names for the same AI, and the number of people using each is small. Furthermore, like "Kuro-san," there are names that some people use for Claude and others use for ChatGPT.
Even looking at the name alone, there are cases where you don't know which generative AI it refers to.
Yoshida looked at the summary table.

"Even if I try to decide on a first place, everyone has almost one vote each."

It's like a state where a world tournament was held, but all the participants started different competitions.
The fact that it didn't become a ranking was the result
In this investigation, I couldn't create a clean country-by-country ranking like "In America, they call ChatGPT XX" or "In South Korea, they call Claude XX."
If you search, you can find many candidate names.
However, whether that name is used by one person, a hundred people, or a million people is another story.
There are also examples where nickname candidates that AI thought of are introduced as "popular names overseas" as they are.
You cannot count a name that someone wrote once and a nickname that has become widely established in society as the same one vote.
For example,
"Overseas, they call ChatGPT Chad."
If you write that, the article becomes easy to understand.
However, what I was actually able to confirm was an example where "there was a workplace that called ChatGPT Chad."
You cannot make the naming of one workplace the culture of the entire English-speaking world.
It's a shame the ranking wasn't completed.
On the other hand, more interesting differences were found.
In Japan, a movement occurred where many people shared one nickname.
Overseas, examples of users giving their own AI a name stood out.
In other words, what was different was not the popular name.
It was the way of naming itself.

From here on, it's not for beginners

"I see. It didn't become a ranking, but it was summarized neatly, right?"

Yoshida tidies up the whiteboard.
When I investigated world generative AI nicknames, I couldn't confirm any nicknames as widely shared as Japan's "Chappy" in other language regions.
Overseas, the focus was on shortened versions of official names or names that individuals gave to their own AI.
It didn't become a ranking.
However, the fact that a ranking could not be established was the result itself.
As an article for beginners, it's a clean landing.

"Alright, I'm going back to Kawamura's place."

However, Kuro-Pagu thought.
Why did it gather to "Chappy" in Japan?
Is the way Japanese sounds are made related?
Is there any characteristic in words that are easy to attach "chan," "kun," and "san" to?
Why were individual names chosen over common nicknames in English?
Is there a relationship between the time when ChatGPT started having human-like conversations and the time when nicknames spread?
Is it a cultural difference?
Is it a language difference?
Is it a difference in service names?
Or is everything related little by little?

"Kuro-Pagu-san?"

A new paper was placed on the desk.
On the cover, it is written like this:

Technical Appendix
Why was the convergence to "Chappy" observed in the Japanese-speaking world?
—A Multi-layered Hypothesis on Phonology, Word Formation, and Interpersonal Cognition of Generative AI Nicknames—

"Wait a minute."

The pages increase.
The structure of Japanese sounds.
How to shorten words when creating nicknames.
The culture of treating non-human things like humans.
The attachment felt toward AI.
The relational usage that spread after GPT-4o.
Proven facts.
Interpretations that do not contradict the facts.
Hypotheses that have not yet been verified.

"I came to make a ranking for beginners."

The appendix does not stop.
Behind the ranking article, comparative linguistics, cognitive science, and cultural anthropology are being built up.
"Kuro-Pagu-san. This is no longer a supplement to the article. It's a research building."
Yoshida held his light blue tie and slowly backed away.
And when he turned around, he started running at full speed.

"Kawamura! Kuro-Pagu-san is building a research building behind the article again!"

Yoshida ran back to his beloved Kawamura.
On the desk, only the uncompleted ranking and the somehow completed technical appendix remained.

Conclusion
What I found this time is not just "what ChatGPT is called in the world."
Even if using the same generative AI, there are cases where everyone shares one nickname, and cases where each person gives their own AI a name.
Japan's "Chappy" appears to be a rare example of the former at this point.
Why did this phenomenon occur in the Japanese-speaking world?
For those who are interested, please proceed to the technical appendix ahead.
Note that Yoshida is no longer here.
He went back to Kawamura-san's place.
