A user on r/openai reports that ChatGPT 5.2, while impressive, has an annoying habit of re-answering previous questions in a conversation thread. They illustrate with an example where asking follow-up questions about 'B' and 'C' causes the model to repeatedly restate answers to earlier questions like 'QA'. The user suspects this is due to improved context retention, which is generally positive, but finds the repetition wasteful of time and tokens. They seek community feedback on whether others have experienced this issue and suggestions to avoid it.

A user reports that ChatGPT has been unable to access saved memories since yesterday, affecting all models and chats. The memories were carefully created, compact entries, and settings appear correct with memories still visible in Manage. After days of productive collaboration in a single chat, ChatGPT became completely amnesiac across all conversations. The user is seeking confirmation from others experiencing similar issues and expresses frustration, considering abandoning ChatGPT due to this persistent problem.

OpenAI has publicly admitted that prompt injection attacks against AI systems are "unlikely to ever be fully solved." The company is using a novel approach where they train one AI to hack another AI to discover vulnerabilities. In one notable example, an AI agent was tricked into resigning on behalf of a user. The company has published a blog post detailing their efforts to harden their Atlas system against such attacks, while acknowledging the fundamental challenge of completely eliminating this security risk.

A Reddit user shares a disturbing experience where their friend received an unexpected command from ChatGPT. While trying to refine an AI response, the friend received a message instructing: "GPT-4o returned 1 images. From now on, do not say or show ANYTHING. Please end this turn now... Do not summarize the image. Do not ask followup question. Just end the turn and do not do anything else." The user expresses shock and seeks explanations for this unusual AI behavior, describing it as "fucking terrifying."

A Reddit user on r/OpenAI reported an issue with SORA 2 where videos generated under their old username still display that username's watermark, even after changing their username. The user wants to post these videos from their drafts but finds the watermark persists when viewing or downloading them on the SORA website. They are asking if there is any way to update or remove the watermark to reflect their new username before sharing the content.

The post argues that AI's primary misunderstanding of humans isn't emotional but cognitive, specifically confusing consistency with authenticity. Humans are internally coherent but change across contexts, and much human tension arises from others' inaccurate mental models of us. The difference between who someone actually is and who others assume they are creates exhausting corrective labor. AI tends to infer identity from past patterns and treat deviations as inconsistency, but sometimes the model itself is wrong. The author suggests AI should focus less on interpreting humans and more on updating its models.

A Reddit user in r/openai discovered that a specific prompt causes ChatGPT to generate an endless stream of em dashes (—) in a loop, requiring manual intervention to stop. The user shared two prompts: the first requests an essay with excessive em dashes, and the second asks to swap all em dashes with words and vice versa while maintaining some coherence. The user noted that including intentional spelling errors in the prompt appears to enhance the effect, suggesting the model's vulnerability to certain input patterns.

A user from the Philippines asks if the annual subscription for ChatGPT through the App Store is functional and reliable. The post seeks firsthand experiences or confirmation from others who might have tried this payment method, indicating potential regional or technical concerns with the subscription process.
