On April 9, 2026, OpenAI quietly introduced a new pricing tier that is worth paying attention to — a $100 per month Pro plan sitting directly between the existing $20 Plus plan and the $200 Pro tier.
The timing is not a coincidence. Anthropic’s Claude Max is also $100 per month. OpenAI is sending a clear message: if you are choosing between the two platforms on price, the answer is now a draw.
So what do you actually get?
The new $100 plan includes unlimited access to GPT-5.4 — OpenAI’s best everyday model — plus access to GPT-5.4 Pro for the most demanding tasks. The main selling point is Codex. For a limited launch period, subscribers get 10 times more Codex usage than the $20 Plus plan. After the promotion ends, it settles at 5 times more.
Update (November 2026): OpenAI now lists ChatGPT Pro at US$100, US$200 or US$500 per month, and its Codex usage tables now list GPT-6-series models rather than GPT-5.4 (OpenAI pricing). In September 2026 OpenAI briefly paused new sign-ups for the US$200 tier and reopened them on September 30 with recalculated usage; the US$100 tier stayed available throughout (Unite.AI).
Codex crossed 3 million weekly users on April 8, growing 5 times in just three months. It is no longer just a code autocomplete tool. Codex can now run background coding jobs, review GitHub pull requests automatically, and work across your terminal, IDE, and browser — all connected through one ChatGPT account.
For a business that employs even one developer, the maths is straightforward. If Codex saves your developer two hours a week, it has already paid for itself by the end of the first month.
For non-developers, the $20 Plus plan remains the most practical option for everyday use — writing, research, summarising, and analysis.
Quick comparison:
Plus — $20/month — Best for everyday individual use New Pro — $100/month — Best for developers and power users needing heavy Codex sessions Original Pro — $200/month — Best for the highest volume usage

Frequently asked questions
How much is the new ChatGPT Pro plan?
The new ChatGPT Pro tier launched on April 9, 2026 at US$100 per month, sitting between the US$20 Plus plan and the US$200 Pro plan. As of November 2026, OpenAI lists Pro plans at US$100, US$200 and US$500 per month, so check the current pricing page before you budget for your team.
What is the difference between ChatGPT Pro $100 and $200?
The main difference is usage, not features. At launch, both Pro tiers shared the same core capabilities, but the $100 plan gave five times the Plus usage (10 times for Codex during a launch promotion that ran to May 31, 2026), while the $200 plan gave 20 times. Choose the higher tier only if you regularly hit limits.
Is ChatGPT Plus enough for a small business?
For most staff, yes. The $20 Plus plan covers everyday writing, research, summarising and analysis, which is what most office roles need. The $100 Pro plan mainly makes sense for developers or power users who run long Codex sessions and keep hitting Plus limits. Many businesses mix plans and give Pro only to the people who need it.
Does the $100 ChatGPT Pro plan include Codex?
Yes. Codex is included in ChatGPT’s paid plans, and the $100 Pro tier was designed for heavy Codex users. At launch it offered five times the Codex usage of Plus, raised to 10 times until May 31, 2026. Before rolling it out, set an AI use policy so staff know what code and data they can share.
