OpenAI has launched a more affordable ChatGPT Pro plan at $100 per month, specifically targeting Codex users who need more advanced AI coding capabilities. The new tier replaces the previous $200 Pro plan, offering five times more Codex usage than the $20 ChatGPT Plus subscription.

This move comes as OpenAI's Codex for Mac app gains traction, with the company reporting 3 million weekly users and 70% month-over-month growth. The Pro plan includes access to exclusive models, unlimited Instant and Thinking models, and temporarily doubled Codex usage through May 31st. OpenAI's pricing strategy creates two distinct Pro tiers: the $100 version for regular users and the $200 tier for those running demanding, continuous workflows.

By introducing this mid-tier option, OpenAI is addressing developer demand while maintaining its premium offering for power users. The pricing shift makes advanced AI coding tools more accessible to a broader range of developers, potentially accelerating adoption of AI-assisted development workflows. With Codex's rapid growth and the new Pro plan's competitive pricing, OpenAI is positioning itself to capture more of the developer tools market.
