OpenAI Introduces New 100 Dollar Monthly Pro Tier for Intensive Codex Use
OpenAI has officially expanded its subscription lineup by adding a new $100/month Pro tier specifically designed for developers and heavy users of Codex, the company’s AI coding agent. Launched on April 9, 2026, this middle-ground option sits between the standard $20 Plus plan and the high-end $200 Pro plan to better support long-form, high-intensity coding sessions.
The new tier provides 5x more Codex usage than the ChatGPT Plus plan and includes unlimited access to GPT-5.4. For a limited time, OpenAI is even boosting this to 10x more usage to encourage adoption. This move comes as OpenAI shifts its $20 Plus plan to focus on steady, day-to-day use rather than prolonged, heavy coding sessions.
