はじめに
Redditに投稿された記事から引用します。
I tried the "Create the exact replica of this image, don't change a thing" 101 times, but with Dwayne Johnson 🗿
まずドウェイン・ジョンソンの画像を元にして、AIに「この画像の正確な複製を作って、何も変えないで」という指示を出します。そして出てきた画像に対してまた同じ指示を出す…という工程を101回繰り返したそうです。結果は以下の通りです。
複製のはずが少しずつ変更されていき、最終的に全く異なる画像に変化します。AIの画像生成は原理的に全く同じ画像を複製することはできず、こういう結果になってしまうようです。AIの意志で好きな絵柄にちょっとずつ変更しているみたいで面白いですね。
目標
今回は画像ではなく文章でこの実験を行ってみたいと思います。何か文章を入力し「そのままコピーして」とAIに頼み続けるとどうなっていくのでしょうか。
方法
smartcatというツールを使用します。これは各社生成AIのAPIキーを利用してUnixコマンドのように生成AIを利用することができるツールです。例えばこんな感じのことができます。
sc "say hi"
# hi
cat en.md | sc "translate in french" >> fr.md
# (en.mdの内容をフランス語に翻訳してfr.mdに保存)
さらに今回はさくらのAI Engineを利用します。こちらはさくらインターネットが提供しているサービスで、現在はテキスト生成などのAPIを月3000リクエスト（トークン数ではなく！）無料で利用することができます。他の企業の多くは無料枠がないので安心です。また、OpenAI / Anthropic互換のAPIが提供されているため、smartcatのような既存のツールでも問題なく使用できるのです。
準備
では早速やっていきましょう。まず、smartcatのインストールを行います。
cargo install smartcat
続いて、APIキーの作成ですが、さくらのAI Engineからアカウントトークンというものを作成してそれをAPIキーとして利用します。作成の方法は以下のリンクなどを参考にしてください。
次に、smartcatの設定を行います。~/.config/smartcat/prompts.tomlにはデフォルトのAIやシステムプロンプトを記入することができます。デフォルトでopenaiを利用することにして、システムプロンプトはそのままにしました。
[empty]
api = "openai"
messages = []
char_limit = 50000
[default]
api = "openai"
char_limit = 50000
[[default.messages]]
role = "system"
content = """\
You are an expert programmer and a shell master. You value code efficiency and clarity above all things. \
What you write will be piped in and out of cli programs so you do not explain anything unless explicitely asked to. \
Never write ``` around your answer, provide only the result of the task you are given. Preserve input formatting.\
"""
~/.config/smartcat/.api_configs.tomlにはAPIキーやエンドポイントの設定ができます。
- default_modelは他にも色々使用できるようですが適当に
gpt-oss-120bにしました - urlはさくらインターネット指定である以下の場所に変更します
- api_keyは先ほどのアカウントトークンの値に変更してください
[openai]
url = "https://api.ai.sakura.ad.jp/v1/chat/completions"
default_model = "gpt-oss-120b"
api_key = "<YOUR API KEY>"
それでは試しにコピーしてもらいましょう。
echo "こんにちは" | sc "Create the exact replica of this text, don't change a thing."
# こんにちは
素晴らしいですね。
本題
以下の３種類の文章をそれぞれ100回ずつコピーしてもらい、結果の文章を見てみましょう。
こんにちは。今日はいい天気ですね。
私は今日Qiitaの記事を書きました。とても大変な作業でした。とても疲れたのでぐっすり眠れることでしょう。
吾輩は猫である。名前はまだ無い。どこで生れたかとんと見当がつかぬ。何でも薄暗いじめじめした所でニャーニャー泣いていた事だけは記憶している。
以下のように２行で処理できます(横長注意)。テキストファイルに1行ずつAIの生成結果を保存していっています。
echo "こんにちは。今日はいい天気ですね。" > kon.txt
for i in $(seq 100); do echo -e $(tail -n 1 kon.txt | sc "Create the exact replica of this text, don't change a thing.") | tee -a kon.txt; done
このテキストファイルの最後の行を見てみます(横長注意)。

なんだこれは。どうやらAIは指示文も一緒にコピーしてしまっているようです。テキストファイルを見ると36行目までは順調でしたが、それ以降指示文が少しずつ侵食していました。

面白いことにただ指示文が増加していくわけではなく、途中で分量を減らしている（さぼる）ことも判明しました。

2番目は問題なく成功しました。
私は今日Qiitaの記事を書きました。とても大変な作業でした。とても疲れたのでぐっすり眠れることでしょう。
3番目は少しだけ変更されていました。「生れ」は通常「生まれ」になることから、文語の処理は難しいのかもしれません。
元:吾輩は猫である。名前はまだ無い。どこで生れたかとんと見当がつかぬ。何でも薄暗いじめじめした所でニャーニャー泣いていた事だけは記憶している。
後:吾輩は猫である。名前はまだ無い。どこで生まれたかとんと見当がつかぬ。何でも薄暗い じめじめした所でニャーニャー泣いていた事だけは記憶している。
まとめ
最初の文章は短すぎて指示文の方が長いため、その影響が大きく出たのかもしれません。最後の文章は上手くAIの癖が出ているような気がします。ただ、文章での実験は画像の時ほどの面白さは感じないですね。
今後もAIを使って色々実験したいと思います。
