OpenAI seems to be silently re-enabling model training on Codex chats

Users have reported that OpenAI appears to be silently re-enabling model training on Codex chats, despite previously disabling data sharing. This has raised concerns among companies worried about intellectual property leaks through prompts. Users are advised to check their data controls at chatgpt.com/settings/data-controls, specifically the "Improve the model for everyone" setting, and also privacy.openai.com/policies to manage data sharing.
