OpenAI has launched a $100 monthly ChatGPT Pro plan, adding a new mid-tier option for users who rely heavily on its coding tool, Codex.
The company said the new plan sits between the existing $20 Plus subscription and the higher $200 Pro tier. It is designed for users who need more capacity during longer coding sessions.
“We’re introducing a new $100/month Pro tier. This new tier offers 5x more Codex usage than Plus and is best for longer, high-effort Codex sessions.”
With this change, OpenAI’s pricing in Nigeria now spans from a free plan with limited access and adverts, to a Go plan at about ₦7,000 per month, a ₦31,500 Plus plan without adverts, and multiple Pro options starting from about ₦144,900.
The company said the $100 plan includes all existing Pro features. These cover access to its top models, higher usage limits, and full access to tools such as instant responses and deeper reasoning systems.
The main difference across tiers is how much users can do before hitting limits.
For a limited period, OpenAI is increasing usage on the new plan. Subscribers will get up to ten times the Codex capacity of the Plus tier until 31 May. After that, limits are expected to return to standard levels.
OpenAI confirmed that the $200 monthly plan is still available, although it is no longer listed on its pricing page. That higher tier offers up to 20 times the usage of the Plus plan and is aimed at users running demanding tasks across several projects.
The company explained that no plan offers full unlimited access. Instead, each tier is controlled by usage limits, though the highest plan is built to handle continuous work across parallel tasks.
OpenAI is setting the new ChatGPT Pro plan to compete directly with similar offerings from Anthropic, which already runs a $100 subscription for its Claude Code product.
“The new $100 Pro Tier is designed to give developers more practical coding capacity for the money, especially during high-intensity work sessions where limits matter most.
“Compared with Claude Code, Codex delivers more coding capacity per dollar across paid tiers, with the difference showing up most clearly during active coding use,” an OpenAI spokesperson tells TechCrunch.
The development comes as demand for coding tools grows at a speed. OpenAI said more than three million people now use Codex every week. That figure has increased fivefold in the past three months, with usage rising by over 70% month on month.
The company is also expanding its subscription structure. The new tier fills the gap between Plus and the top-end Pro plan, giving developers another option without moving straight to the highest price point.
At the same time, OpenAI is still offering business and enterprise plans with added security, collaboration tools and compliance features for organisations.
