OpenAI announced on Thursday something that power users have been asking for forever: a $100/month plan. Until now, plans were priced at: free (which now includes ads), an $8/month Go plan (that also includes ads), a $20/month Plus plan (ad free), and then all the way up to a $200 Pro plan (also ad free).

OpenAI’s pricing plan page currently does not list a $200/month plan at all. However, that highest tier is still available, OpenAI confirmed to TechCrunch.

The model maker says Plus (which remains at $20/month) and the new $100 Pro tier are geared to support daily usage of ChatGPT’s coding tool Codex. The $100 Pro plan will offer 5x more Codex than the Plus plan.

OpenAI makes no bones that this new pricing tier is to challenge Anthropic, which has long had a $100/month option for Claude.

“The new $100 Pro Tier is designed to give developers more practical coding capacity for the money, especially during high-intensity work sessions where limits matter most. Compared with Claude Code, Codex delivers more coding capacity per dollar across paid tiers, with the difference showing up most clearly during active coding use,” an OpenAI spokesperson tells TechCrunch.

One thing to know: OpenAI is offering even higher limits of Codex on the $100 plan through May 31. So anyone who tries the new tier, goes relatively mad with coding and never gets a rate warning: Be advised that such a situation likely won’t last.

None of the plans offer unlimited usage. The $200 plan, however, offers 20× higher limits than Plus. The model maker promises on its FAQ that this is enough to support “your most demanding workflows continuously, even across parallel projects.” Both Pro plans offer the same core features. The main difference is the rate limits, the company says.

The spokesperson also says that more than 3 million people globally are using Codex every week, “up 5x in the past three months, with usage growing more than 70% month over month.”
