OpenAI has started selling a premium tier for ChatGPT Business that costs $100 per user per month on annual billing — or $125 month-to-month. That's exactly five times the price of the standard seats, which still run $20 and $25. The usage allowance also scales up fivefold, and the five-hour usage limit is gone.
Companies don't have to upgrade everyone. You can keep everyday employees on Standard and reserve Premium for heavy users. Both tiers include ChatGPT, ChatGPT Work, and Codex, and admins can swap seats around whenever they need to.
