TL;DR

OpenAI added a $100/month ChatGPT tier with 5x Codex usage vs Plus ($20/month). ChatGPT already had a $200/month Pro plan with ~20x Codex vs Plus; both use the Pro name. Through May 31, 2026, new $100 Pro subscribers get up to 10x Codex usage vs Plus as a launch promo. OpenAI also said it is rebalancing Plus Codex limits toward more sessions across the week.

What Happened

OpenAI posted on X about a new subscription meant for heavier Codex use. Reporting from MacRumors summarizes the structure: the $100/month tier offers 5x the Codex usage of Plus; ChatGPT already included a $200/month Pro option with a ~20x Codex allowance vs Plus—the $100 plan is an additional middle step. Both the $100 and $200 plans are branded Pro.

The $100 tier targets longer, high-effort Codex sessions. For a limited time, through May 31, 2026, subscribers to the $100 Pro plan can receive up to 10x Codex usage relative to Plus (per MacRumors, matching OpenAI’s wording). OpenAI is also rebalancing Codex limits on Plus so users get more sessions spread across the week rather than spikes on a single day.

Anthropic’s consumer ladder ($20 Pro, $100 Max 5x, $200 Max 20x) is the obvious comparator; OpenAI’s move makes the two vendors’ price/usage steps easier to compare directly.

Key Facts

Tier	Monthly price	Codex vs Plus (reported)	Notes
Plus	$20	Baseline (1x)	OpenAI: best for steady day-to-day Codex use; limits rebalanced
Pro (new mid)	$100	5x; 10x promo through May 31, 2026	New middle option between Plus and $200 Pro
Pro (existing high)	$200	~20x	Already existed; same “Pro” brand as $100 tier
Enterprise / custom	Varies	Not detailed in summary sources	Separate contracts

• Naming: Two different monthly prices both called Pro ($100 and $200)—readers need the price to disambiguate.
• Promo: 10x is time-limited (ends May 31, 2026) and applies to the $100 Pro plan per cited coverage.
• Plus change: Codex usage on Plus is being rebalanced for more frequent sessions (per MacRumors/OpenAI).

Coverage often frames this as “one new Pro tier,” but the structural signal is a three-step consumer ladder (Plus → $100 Pro → $200 Pro) that more closely mirrors Anthropic’s $20 / $100 / $200-style spacing. The awkward shared Pro label on two different prices increases comparison-shopping confusion and may push readers to use price as the real SKU.

Key Implication: Heavy Codex users who outgrew Plus but did not want $200 now have a defined step; the May 31 promo accelerates trials of that step. Watch whether OpenAI clarifies naming (e.g. Pro vs Pro+) to reduce support and SEO ambiguity.

What This Means

For individual developers and power users, the $100 tier offers a predictable step for heavy Codex usage without jumping to $200. The time-limited 10x promo is effectively an extended trial window for that tier. Users who already need ~20x vs Plus remain on the $200 Pro plan.

For OpenAI’s competitive positioning, the lineup now maps more cleanly onto Anthropic-style $20 / $100 / $200 usage ladders, reducing a positioning gap for shoppers comparing Codex and Claude Max-style tiers.

For the broader AI subscription market, expect clearer usage-tier competition at $100 and $200 price anchors, not only Plus vs enterprise. Watch whether Google and others publish equally explicit coding-agent quotas at those price points.
