We're updating ChatGPT Pro and Plus subscriptions to better keep pace with the growing use of Codex.
We're introducing a new $100/month Pro plan. The new plan offers 5x more Codex usage than Plus, and is best suited for longer, high-intensity Codex sessions.
In ChatGPT, this new Pro plan continues to provide access to all Pro features, including unlimited access to Pro-exclusive models and the Instant and Thinking models.
To celebrate the launch, we're temporarily increasing Codex usage through May 31. Pro $100 subscribers can use up to 10x the Codex usage of ChatGPT Plus, letting you bring your most ambitious ideas to life.
The Codex promotion for existing Plus subscribers ends today, and we're recalibrating Plus's Codex usage accordingly. We'll enable more sessions spread across the week rather than one long session at a time during the day.
The Plus plan stays at $20, which is best suited for using Codex reliably in your everyday work, while the new $100 Pro plan offers an easier upgrade path for those who use it more each day.

For those unfamiliar with the existing plans, here's some additional context:
There was a $200/month Pro plan (299,000 won in Korea), and now a new plan has been added between Plus and the existing Pro.
The $100 plan (159,000 won/month) is "10x compared to Plus" for a limited time, and is said to be limited to 5x afterward.
