OpenAI Cuts ChatGPT Pro Pricing to $100/Month for Codex Users

OpenAI has introduced a new $100/month ChatGPT Pro tier designed specifically for Codex users, reducing the price of its highest-tier subscription from $200/month. Both Pro plans remain available, differentiated solely by usage allowances.

Pricing and Feature Breakdown

Pro $100/month: 5x higher usage limits than ChatGPT Plus. During a limited promotional period through May 31, Codex users on this tier receive up to 10x the Codex usage available to Plus subscribers.

Pro $200/month: 20x higher usage limits than ChatGPT Plus, intended for continuous, heavy-duty workflows including parallel projects.

OpenAI confirms both tiers include "the same core capabilities," with usage allowance as the only differentiator. Both provide access to exclusive models and unlimited access to Instant and Thinking modes.

Codex Momentum

The timing aligns with significant adoption growth for Codex, OpenAI's coding-focused AI model. The company reports:

• 3 million weekly active users as of the announcement
• 5x user growth in three months
• 70% month-over-month usage growth

Codex, available as a macOS application since February 2026, has driven demand for higher usage tiers beyond the $20/month ChatGPT Plus plan.

Market Context

The new $100/month tier addresses a gap for developers who require more than Plus allows but previously faced the steep jump to $200/month. This pricing structure mirrors tiering strategies in competitive developer-focused AI services, where mid-market pricing targets active professionals.

The promotional 10x Codex bonus (available through May 31) functions as a limited-time acquisition incentive for the new tier.

What This Means

OpenAI is explicitly segmenting its subscription market by developer intensity rather than model capability. The $100 tier targets Codex's fastest-growing user cohort—professionals using AI coding daily but not at enterprise scale. Maintaining the $200 tier preserves revenue capture from high-volume users while the new pricing removes friction in the mid-market. Codex's 5x growth in three months suggests this positioning was strategically timed, with the tier designed to convert power users before they seek alternatives.
