OpenAI Puts 5-Hour Cap on ChatGPT Coding Tool — What That Means

OpenAI put a time limit back on ChatGPT Plus users who use its coding tool, Codex. Starting Aug. 25, after five hours of using Codex or ChatGPT Work, you hit a wall and must wait for the five-hour clock to reset — or pay extra for more usage. This applies in addition to the weekly allowance. The five-hour rule was actually removed in July to give users more freedom, but now it's back.

Why the change? OpenAI says it helps spread out the heavy computing load. Think of it like a gym with a few treadmills — if everyone runs for six hours straight, others can't get a turn. By limiting sessions to five hours, the company keeps service stable for everyone. It also prevents casual users from accidentally using up their entire week's allowance in one afternoon and being confused later.

What this means for you. If you use ChatGPT Plus for serious coding, you'll need to keep an eye on both the five-hour and weekly counters. This is especially important if you're in a long coding session — you might get cut off even if you haven't used your whole weekly quota. Developers who pay $100 or $200 per month are exempt for now, and so are business accounts, which use a different credit system.

OpenAI's move shows how AI companies are struggling to balance user demand with the cost of running giant computers. As AI tools become more popular, expect more usage caps and limits. It's a reminder that "unlimited" plans often come with fine print.
