OpenAI launches Codex Pro $100 subscription; users praise new tier

OpenAI has added a new $100-a-month Pro tier built around Codex, its coding product, creating a lower-priced option between ChatGPT Plus at $20 and the company’s existing $200 Pro plan. OpenAI announced the change on April 9 in its developer community forum and now lists the tier on its Codex pricing page. The company says the new plan offers higher Codex limits than Plus and includes the rest of the ChatGPT Pro feature set. Social posts from users in recent weeks have focused less on the launch itself than on how far the new limits appear to go in practice. ### When did OpenAI actually launch the $100 plan? OpenAI posted the change on April 9, 2026, in a developer community announcement titled “Introducing New $100/month Pro Tier.” The company said it was “updating” its ChatGPT Pro and Plus subscriptions to support heavier Codex use and described the new tier as aimed at “longer, high-effort Codex sessions.” The Codex pricing page now lists individual plans from Free to Go, Plus and Pro, with the Pro card marked “From $100/month.” That page says the plan includes “5x or 20x higher rate limits than Plus,” depending on tier, and links users to ChatGPT Pro signup pages. ### What does the $100 tier include? OpenAI’s pricing page says the $100 Pro tier includes everything in Plus, access to Codex across the web, CLI, IDE extension and iOS, and access to GPT-5.3-Codex-Spark, which it describes as a research preview for day-to-day coding tasks. (community.openai.com) The page also says the standard allowance for that tier is 5x Plus-level Codex usage. (developers.openai.com) OpenAI’s Help Center says Codex usage is not expressed as a fixed message count. Instead, usage depends on the size and complexity of tasks, the amount of context held in memory and where tasks are executed. That means two subscribers on the same plan can see very different depletion rates. ### Why are users talking about “10x” limits through May 31? (developers.openai.com) OpenAI’s Help Center says the $100 Pro tier is running with a launch promotion that doubles normal Codex usage through May 31, 2026. The company says that turns the standard 5x limit into 10x during the promotional period. The same Help Center article says OpenAI’s $200 Pro tier continues to carry a higher Codex allowance, listed as 20x Plus on an ongoing basis. (help.openai.com) A release-notes page also says the higher Codex promotion for the $200 plan remains in place through May 31. ### Are the social posts about “85% remaining” official usage data? (help.openai.com) User posts on X and OpenAI’s community forum have described the $100 tier as more generous than expected, including anecdotal reports that heavy app or game-building sessions still left most of the allowance untouched. Those posts are user claims, not OpenAI disclosures, and OpenAI’s public documentation does not provide a universal percentage-to-task conversion table. (help.openai.com) OpenAI’s own rate-card article says Codex usage can average roughly $100 to $200 per developer per month, but it says there is “large variance” based on model choice, number of running instances, automations and fast-mode use. That framing is closer to infrastructure consumption than to a simple prompt counter. ### How do API discounts fit into the discussion? (community.openai.com) OpenAI’s API pricing page lists cached-input pricing at one-tenth of the standard input price for GPT-5.5, which amounts to a 90% discount, and shows Batch processing at 50% off standard pricing. Those are API pricing mechanics, not the same thing as ChatGPT subscription limits, but users have cited them as part of the broader economics of building with OpenAI tools. (help.openai.com) The Codex pricing page draws that line directly. It says the API-key option is meant for automation in shared environments such as continuous integration, while ChatGPT plans bundle Codex access with subscription-based usage limits and cloud features such as GitHub code review and Slack integration. ### What happens after May 31? (openai.com) May 31, 2026, is the date OpenAI names for the temporary doubling of Codex usage on the $100 Pro tier. After that date, the company’s Help Center says the $100 plan reverts from 10x Plus usage to its standard 5x level unless OpenAI extends the promotion. OpenAI continues to publish plan details on its Codex pricing page, Help Center articles and developer forum announcements, which are the company’s primary sources for any further change in limits, pricing or model access.
