Note
An open letter on Pro subscriptions
Predictable subscription terms, verifiable allowances and a corrected correspondence timeline.
I have published an open letter on my decision to stop renewing the $200 ChatGPT Pro subscription.
Update, 30 October 2026: Tibo announced on 29 October that Pro 200 Work and Codex usage would stay the same and that usage limits for Pro 100/200/500 and Business Premium would double. I have marked the open letter closed. The page retains the original requests and corrected correspondence timeline. Read the announcement.
