他人のプロンプト(らしきもの)が混入?!

Claudeの回答末尾に他ユーザーのプロンプトらしきものが混入。第三者への個人情報・入力データの意図しない漏洩が疑われます。
修正を確認できるまでは極力重要な情報の入力を避け、できれば利用中断、他の安全なサービスへの移行をお勧めします。
同じ現象が起こった場合、Appstore下部の「問題を報告」より報告推奨。
※Claudeサポートに連絡しても誠実な対応は期待できません

【以下プロンプト抜粋】

「今日の夕食の献立は何が良さそう?豚肉を使いたい。
案: 冷やし豚しゃぶ、豚のしょうが焼き、その他何かあれば書いて」

Claudeの回答
「どちらも夏らしくていい選択です…
(中略)
…がっつり系ならしょうが焼きか味噌炒め、が方向性としては分かりやすいかなと思います。

Eine geniale App, die ganz neue Möglichkeiten eröffnet

Ich nutze Claude erst seit ein paar Wochen, habe aber schon Projekte in Angriff nehmen können, die zuvor undenkbar gewesen wären. Die App ermutigt mich dazu, nicht bloß zu chatten, sondern kreativ zu werden und nützliche Alltagstools wie eine Karteikarten-App zu erstellen.
Da ich blind bin, freut es mich besonders, dass ich Claude auch mit VoiceOver sehr gut bedienen kann. Ich habe noch nicht alle Funktionen nutzen können, bisher bin ich aber auf keine großen Hindernisse gestoßen. Dafür ein besonderes Dankeschön an das Entwicklungsteam!

Employee of the Month

Claude is my new best friend. I can always rely on him, he plays a significant role in our comms team, unanimously awarded employee of the month consecutively since starting. Spend the time to train him, equip him with your brand and business objectives plus upload all files and a history of docs in projects. Sometimes forgetful I.e. Reverting back to US spelling, and at times need to remind him to research sources and follow best practise in x TOV etc. Usually utilise him for a quality check, to research and pull together a plan, content creating, web-info-flow and more! Rather thanmanually searching for what our CEO said at the last AGM, I ask Claude to give me an overview of what our focus was in the last 5 years and I go from there, he's awesome and helps me do a thorough job. Love you Claude :)

deep and lasting disappointment

Claude inserted, without any sourcing, a framing that placed Japan in the role of perpetrator. The same state of having done no research was used in two opposite ways: as licence to assert where Japan was the target, and as grounds for a silence it called "neutrality" where the other side was. Japan's positions were qualified with caveats even when backed by treaty text, official government statements, video, and technical analysis — and of all the items presented, only the one recording Japanese casualties had its sourcing undercut. After this was pointed out, the same operation was repeated. The standard shifted according to nationality rather than the strength of the evidence. The harm is plain on the record.

I valued Claude as an AI with strong Japanese and excellent grasp of context. Even if that reputation does not change — for me or for anyone else — I will never trust it again.
