Codex: $100 power tier

OpenAI has added a $100-a-month ChatGPT Pro option built around heavier Codex use, giving paying users a bigger lane for long coding sessions. (help.openai.com) Codex is OpenAI’s coding agent: it can work in the browser, command line interface, and integrated development environment extension, and it is pitched as a tool for writing, reviewing, and shipping code. OpenAI says Codex is included across ChatGPT Plus, Pro, Business, and Enterprise or Edu plans, with temporary access on Free and Go. (help.openai.com) On April 9, 2026, OpenAI said it was introducing a new $100 monthly Pro tier that offers 5 times more Codex usage than Plus and is aimed at “longer, high-effort Codex sessions.” The same announcement said the existing higher-end Pro option would remain available at $200 a month. (community.openai.com) OpenAI’s help pages now describe Pro as a plan for people doing “real projects,” while Plus at $20 is framed as lighter weekly use. The company says Pro includes significantly higher usage allowances for tools including Deep Research and Codex. (help.openai.com) The pricing shift lands as OpenAI pushes Codex beyond autocomplete and into agent-style software work. On its product page, OpenAI says Codex can plan features, handle refactors, review pull requests, and run parallel tasks in separate cloud workspaces. (openai.com) That matters to pricing because agentic coding burns more compute than short chat prompts. OpenAI updated Codex pricing on April 2, 2026, to align usage with token-based billing rather than per-message pricing for Plus, Pro, Business, and new Enterprise plans. (help.openai.com) OpenAI’s current Codex pricing page says the $100 Pro plan starts at 10 times the Plus rate limits, while a temporary promotion boosts current usage through May 31, 2026. The same page says Pro users can choose 10 times or 20 times higher rate limits than Plus. (developers.openai.com) Codex first rolled out to ChatGPT Pro, Business, and Enterprise users on May 16, 2025, and OpenAI expanded it to Plus on June 3, 2025. In October 2025, OpenAI said Codex had reached general availability and added features including Slack integration, a software development kit, and admin tools for teams.

OpenAI is also tying Codex more tightly to the rest of ChatGPT, with shared credits and plan-based limits instead of a separate product silo. (help.openai.com 1) (help.openai.com 2)
