Custom GPTs die Dec 11: if you use someone else's GPT, you can't migrate it

OpenAI's custom GPTs retire Dec 11 (deferred Enterprise workspaces get until Feb 11, 2027), and most coverage misses the group affected most: people who use GPTs made by others.

Per the official FAQ:

You cannot migrate someone else's GPT — "permission to use it does not let you migrate it yourself"
Access to the original doesn't carry over to a replacement plugin; migrated plugins start private, and publishing one requires a separate submission
Migration uses only the latest published version (drafts don't transfer), the original becomes read-only and undeletable, the chosen model doesn't carry over, and custom actions calling external services must be rebuilt, possibly as MCP servers
Old chats remain accessible, but the GPT page itself disappears

The author's to-do list: inventory the GPTs you'd miss and their creators, check for replacement links, save 3-4 familiar prompts per GPT to compare replacement behavior, and creators should publish final edits before migrating. (Post includes a plug for the author's own product.)
