OpenAI launched a $100/month Pro plan on Thursday, slotting a new option between ChatGPT Plus at $20 and the existing Pro at $200. The pitch: heavy Codex users who keep bumping into Plus limits but can't justify the full $200.
The new tier includes 5x more Codex usage than Plus, access to GPT-5.4 Pro, and unlimited Instant and Thinking models. Through May 31, OpenAI is temporarily bumping that to 10x Codex usage over Plus as a launch promo. The $200 plan sticks around with 20x limits. Both share the "Pro" name, which is exactly as confusing as it sounds.
The timing is no accident. 9to5Mac reports OpenAI now claims over 3 million weekly Codex users, a 5x jump in three months with 70% month-over-month growth. Those are company-reported numbers. The $100 price point also mirrors Anthropic's Max 5x tier for Claude, making the competitive positioning obvious.
OpenAI is also "rebalancing" Codex usage within Plus to spread sessions across the week rather than letting users burn through limits in a single day. That's a nice way of saying Plus users may notice tighter daily caps. The real question: whether $100 buys enough headroom for serious coding sessions or just nudges power users toward $200 anyway.
Bottom Line
OpenAI's new $100/month Pro plan gives Codex-heavy users 5x the usage of Plus, with a temporary 10x boost through May 31.
