OpenAI (ChatGPT): OpenAI's Tibo (@thsottiaux) posted that usage limits are doubled for all Pro 100/200/500 tiers and Business Premium, effective today, and that the planned Pro 200 usage-limit reduction will not happen. OpenAI's help article (captured Oct 30, 2026, 8:20 AM CT) is narrower: Pro 100 and Pro 500 doubled; on Pro 200 only the lower allowance doubled; Plus is unchanged.
Old OpenAI Help Center (read Oct 29, 2026, 8:12 AM CT): grandfathered Pro 200 subscribers keep the previous included allowance through October 29, 2026, then "move to the lower included usage allowance".
New "We are doubling all usage limits for all Pro 100/200/500 tiers and Business Premium, effective today." "We heard your kind feedback and won't be reducing usage limits for Pro 200, so your Work and Codex usage will stay the same."
