Custom GPTs retire Dec 11: chats won't migrate to Projects, key FAQ points
Ok_Negotiation_2587 · reddit · 2026-11-15
With OpenAI retiring custom GPT pages on Dec 11, a Reddit user highlights easily-missed lines from the official retirement FAQ:
- Chats can't follow the GPT into a Project: existing conversations stay in your history but can't be moved in — the new Project starts empty, though old chats remain accessible after retirement.
- For self-built GPTs: migration to a plugin uses only the latest published version (drafts don't transfer), the selected model doesn't carry over, custom actions must be rebuilt, and the original becomes read-only and undeletable once migrated.
The author recommends copying out your GPT's instructions this week, pasting them into Project settings, uploading reference files manually, and running known prompts side-by-side to compare outputs. The post ends with a promo for the author's browser extension AI Toolbox, which organizes chats across GPTs and Projects into folders with full-text search.
