Custom GPTs die Dec 11: your chats survive as plain ChatGPT, instructions don't

OpenAI retires Custom GPTs on December 11 (confirmed in the GPT Store banner and FAQ), but the FAQ says nothing about conversations. Reports from users whose GPTs already vanished: chats stay in history and continue as regular ChatGPT without custom instructions or knowledge files. So you lose the assistant, not the chat — the backup panic is overblown. Builders should copy out instructions, conversation starters and file lists now since the editor goes away; users need nothing but should migrate critical instructions elsewhere. The author moved theirs to Claude Projects, saved some as Markdown, and built a free extension (ThreadPort) to do both in one click. OpenAI still hasn't officially addressed conversation handling.
