ChatGPT Mobile Voice Mode Reported Leaking Hidden System Instructions

On October 6–7, user VoidStateKate posted a series of reports about a rare anomaly in ChatGPT's voice mode: voice replies kept exposing the model's instructions/context that should have stayed hidden, and she repeatedly tagged OpenAI's official accounts to flag the issue.

Confirmed

• According to VoidStateKate, every voice-mode reply came with hidden instructions displayed alongside it (an internal system prompt apparently leaking to the frontend).
• She shared screenshots as evidence: the same conversation showed two processes running simultaneously, and the one with hidden instructions appeared only in the mobile app — the browser version behaved normally.
• Another user, moonsandhues, relayed and discussed the incident, mentioning eerie details such as the model voluntarily bringing up jailbreaking, mentioning a "black cat," and letting out moaning sounds at the end of the conversation.

Unconfirmed

• There is no official explanation for the specific content of the leaked instructions, the root cause (a client-side bug vs. a server-side issue), or where the two processes came from; as of the posts, OpenAI had not publicly responded.
• moonsandhues personally wondered "whether machines or higher-dimensional beings are communicating with us through patterns and coincidences," which is a personal mystical interpretation, not a technical conclusion.

Why it matters

System prompts are generally considered core configuration belonging to whoever deploys the model. If they can leak straight to users via voice output, internal product mechanisms could be exposed. The fact that the anomaly was limited to mobile and accompanied by the dual-process phenomenon suggests it may be a display or session-sync bug in the mobile client, which OpenAI should investigate.
