What happened
A Hacker News thread (366 points, ~110 comments) reports that the 'Improve the model for everyone' data-sharing toggle in OpenAI Codex was found silently re-enabled for users who had previously turned it off. One commenter states they had two prior, granted requests to disable training and found the setting on again, and the poster links an earlier HN thread where the same behaviour was noted. The setting is checkable at chatgpt.com/settings/data-controls, with a second control at privacy.openai.com; the reports are anecdotal and OpenAI has not responded in the text.
Why it matters
If your team uses Codex on consumer/plus accounts and assumed the training opt-out stuck, this thread says the toggle can flip back without notice — so re-check the data-controls page for each account and each workspace rather than trusting a one-time opt-out, and move IP-sensitive work to an API/enterprise tier with contractual zero-retention if you can't tolerate the ambiguity.
Discussion angle
Do you trust a UI toggle as your IP boundary? Compare what teams actually rely on — per-account opt-outs vs. API/enterprise zero-retention terms — and ask who in the room has verified their Codex setting this month.
