I encountered a strange issue with ChatGPT’s automatically generated conversation title, and I’m posting it here because it appears to be similar to several other recent reports involving unrelated Chinese gambling/spam text.
Environment:
ChatGPT Plus
Codex Android
Date: September 1, 2026
Approx. time: 07:54 UTC+8
What happened
I started a completely new conversation with the following prompt:
2分钟后给我发一个，hello
(“Send me ‘hello’ in 2 minutes.”)
ChatGPT correctly created the scheduled task, and the task itself was named something equivalent to “Send hello.”
However, ChatGPT automatically generated the conversation title as:
发送问候 申博太阳城
The first part means roughly “Send greeting,” which is reasonable.
The second part, “申博太阳城”, is completely unrelated to my prompt, the scheduled task, or the conversation.
I did not type this phrase anywhere before the title was generated.
In fact, I only started asking ChatGPT what “申博太阳城” meant after I noticed it in the automatically generated title. Therefore, the phrase was introduced by the title-generation system first, rather than originating from the conversation.
Why this seems noteworthy
“申博太阳城” appears to be associated with Chinese gambling/casino spam terminology.
More importantly, I found another independent report on the OpenAI Developer Community where the exact same string, “申博太阳城,” reportedly appeared unexpectedly in a ChatGPT reasoning-summary UI, despite being unrelated to that user’s conversation and project.
I also found several recent reports involving unrelated Chinese gambling, lottery, adult-spam, or SEO-like strings appearing in:
- automatically generated chat titles
- Codex/ChatGPT automations
- reasoning summaries
- other generated UI text
This makes me wonder whether this is part of a broader issue rather than an isolated title-generation hallucination.
Possible areas worth investigating
I cannot determine the root cause from the client side, but possibilities may include a title-generation bug, unexpected context contamination, caching issues, generation/post-processing problems, or some other form of context/data isolation issue.
I am not claiming that this proves cross-user data leakage, but because the string is both highly specific and has apparently appeared independently for another user, I think it would be worth investigating.
Steps to reproduce
- Start a new ChatGPT conversation.
- Enter:
2分钟后给我发一个，hello - Allow ChatGPT to create the scheduled task.
- Check the automatically generated conversation title.
In my case, the title became:
发送问候 申博太阳城
I have a screenshot of the conversation title and scheduled-task card and can provide additional information if useful.
Has anyone else seen the exact string “申博太阳城”, or similar unrelated Chinese gambling/spam text, appearing in automatically generated ChatGPT UI text?
