OpenAI introduces ChatGPT Pro $100 tier with 5X usage limits for Codex compared to Plus

OpenAI is making moves to try and court more developers and vibe coders (those who build software using AI models and natural language) away from rivals like Anthropic.

Today, the firm arguably most synonymous with the generative AI boom announced it will begin offering a new, more mid-range subscription tier — a $100 ChatGPT Pro plan — which joins its free, Go ($8 monthly), Plus ($20 monthly) and existing Pro ($200 monthly) plans for individuals using ChatGPT and related OpenAI products.

OpenAI also currently offers Edu, Business ($25 per user monthly, formerly known as Team) and Enterprise (variably priced) plans for organizations in said sectors.

Why offer a $100 monthly ChatGPT Pro plan?

So why introduce a new $100 ChatGPT Pro plan, then?

The big selling point from OpenAI is that the new plan offers five times greater usage limits on Codex, the company's agentic vibe coding application/harness, than the existing, $20 monthly Plus plan.

As OpenAI co-founder and CEO Sam Altman wrote in a post on X: "It is very nice to see Codex getting so much love. We are launching a $100 ChatGPT Pro tier by very popular demand."

However, alongside this, OpenAI's official company account on X noted that "we’re rebalancing Codex usage in [ChatGPT] Plus to support more sessions throughout the week, rather than longer sessions in a single day."

That sounds a lot like OpenAI is also simultaneously reducing how much ChatGPT Plus users can use its Codex harness and application per day.

What are the new usage limits for the new $100 ChatGPT Pro plan vs. the $20 Plus?

OpenAI's Developer website notes that for individual users, usage is categorized by "Local Messages" (tasks run on the user's machine) and "Cloud Tasks" (tasks run on OpenAI's infrastructure), both of which share a five-hour rolling window.

The larger strategic implications and context

OpenAI’s sudden move toward the $100 price point comes amid the unprecedented financial ascent of its chief rival, Anthropic. Just days ago, Anthropic revealed its annualized run-rate revenue (ARR) has topped $30 billion, surpassing OpenAI's last reported ARR of approximately $24–$25 billion.

This growth has been fueled by the massive adoption of Claude Code and Claude Cowork. The competitive friction intensified on April 4, 2026, when Anthropic officially blocked Claude subscriptions from being used to provide the intelligence for third-party agentic AI harnesses like OpenClaw.

OpenClaw’s creator, Peter Steinberger, was hired by OpenAI in February 2026 to lead their personal agent strategy. By hiring Steinberger and subsequently launching a Pro tier that provides the high-volume capacity Anthropic recently restricted, OpenAI is effectively courting the displaced OpenClaw community to reclaim the professional developer market.
