OpenAI has been doing the same thing gradually. Codex launched with generous Plus limits, then they introduced the $100 Pro tier, and Plus limits have quietly tightened since. With the same repetitive tasks I was running, consumption is noticeably higher now for the same output.

The pattern feels deliberate — make the $20 tier just uncomfortable enough that power users upgrade, without officially announcing the reduction. If it continues, $20 buys you a demo and $100 buys you actual work.
