Just when it felt like ChatGPT pricing couldn’t get any more confusing, OpenAI has added yet another tier to the mix, and this one sits right in the middle with a neat $100/month price tag.

And no, this isn’t just a random new plan. It’s very clearly aimed at a specific kind of user… the kind who’s already pushing ChatGPT way harder than most people.

OpenAI’s new $100 plan is built for heavy users

OpenAI has introduced a new $100/month ChatGPT Pro tier, positioned between the $20 Plus plan and the existing $200 Pro plan. The focus here is pretty clear: Codex users and power users who need more than what Plus offers, but don’t want to go all the way up to $200. This new tier brings significantly higher usage limits: around 5x more than Plus, and even temporarily up to 10x more Codex usage.

And there’s a good reason for that push. OpenAI says Codex now has over 3 million weekly users, growing 5x in just three months with around 70% month-on-month growth. That kind of surge makes it pretty clear why the company is carving out a dedicated pricing tier for these heavy workflows.

On top of that, the plan includes access to more advanced models, deeper research tools, and expanded capabilities for agent-style tasks. In short, this isn’t meant for casual users, but for people treating ChatGPT like a serious work tool.

Not just a new plan, but a pricing shift

This move signals a clear shift toward usage-based pricing, where heavier AI use comes at a higher cost. Given how expensive advanced workloads are, a one-size-fits-all plan was never going to last.

But it also changes the vibe. What started as a tool for everyone is slowly becoming tiered by affordability. And if $100 is now the middle ground, AI is starting to look a lot like a premium subscription ladder.
