ChatGPT Pro has three tiers: $100, $200, and $500/month. Pro $100 is the published 5x tier. New, non-grandfathered Pro $200 subscriptions receive a lower allowance than before; OpenAI has not published its replacement multiplier. Eligible subscribers keep their previous allowance through October 29, 2026, then move to the lower allowance. Pro $500 has the highest included Pro usage and Astra Ultrafast, with no published numeric multiplier.
What is the ChatGPT Pro Codex Quota
Pro $200 is available for new subscriptions again at $200/month. OpenAI says it includes more usage than Pro $100. Grandfathering preserves only the previous allowance temporarily; it does not add Pro $500 features or Ultrafast.

How to Check Your Pro Quota in the CLI
Running /status in an active Codex terminal session shows the allowance information available for your account. Pro $100, $200, and $500 currently have no five-hour usage limit in Work and Codex, but still have included usage allowances. Check Settings > Usage for remaining allowance and reset times.
Plus vs. Pro $100, Pro $200, and Pro $500
The earlier published Pro 5x and Pro 20x estimated-message columns below are references, not current five-hour caps. The Pro 20x figures preserve the previous allowance; they do not establish the current allowance for every Pro $200 subscription. OpenAI has not published replacement Pro $200 or Pro $500 message ranges. Current OpenAI usage guidance says Pro $100, $200, and $500 have no five-hour usage limit. Included usage is still limited.
OpenAI estimates 15 to 160 local GPT-6.1 Sol messages per five-hour window for Plus and Business Standard, but publishes no corresponding Pro estimate. See GPT-6.1 Sol availability and usage limits for current access, model selection, and credit rates.

Pro $200 is available for new subscriptions with a lower allowance for non-grandfathered accounts; OpenAI has not published its replacement multiplier. Eligible grandfathered subscribers keep the previous allowance through October 29, 2026 while subscribed, then move to the lower allowance. Earlier published Pro 5x and Pro 20x message estimates are historical evidence, not current five-hour caps or proof of current Pro $200 entitlement. Pro $100, $200, and $500 currently have no five-hour usage limit in Work and Codex, but still have included usage allowances. Pro $500 has the highest included Pro usage and Astra Ultrafast, with no published multiplier or model-specific message estimate. Eligibility covers subscriptions active at OpenAI's cutoff or during the seven days before it; OpenAI does not state the cutoff date in this article. Check your account or affected-subscriber email.

When Does Pro Quota Reset?
Pro $100, $200, and $500 currently have no five-hour usage limit in Work and Codex. Weekly limits may still apply, and exact weekly allowances remain unpublished. The legacy Pro 20x estimates do not establish every current Pro $200 account's allowance. Check Settings > Usage for remaining allowance and reset times.
5-Hour Usage Window
OpenAI says Pro $100, $200, and $500 have no five-hour usage limit in Work and Codex. This does not mean unlimited included usage. Check Settings > Usage for your current remaining allowance and actual reset timing.
Account-Specific Anchor
Your weekly window resets on a schedule tied to your account, visible in /status.
For more on reset timing, read when your Codex usage resets.
What Happens When Pro Hits the Limit?
You have more headroom on Pro, but the behavior at the ceiling is the same as Plus: Codex can finish the turn it is on, subject to fair-use limits, then further prompts pause until reset. Your local repository, git history, and unstaged changes are untouched.
The state above shows an exhausted weekly allowance, so waiting a couple of hours will not help. Where it is available on your account, authenticating with an API key routes work to the separately metered OpenAI Platform API instead of your subscription, which is billed per token rather than against your Pro allowance.

Choosing Between Plus and the Three Pro Tiers
Pro costs $100, $200, or $500/month. Pro $200 has a transitional allowance; Pro $500 has the highest included usage and Astra Ultrafast. Which one you want comes down to how much you run and how often you get paused — check /status during your regular workflow.
Which one fits you
- You rarely or never hit the 5-hour or weekly window.
- Your usage is mostly interactive, single-file edits.
- You use Codex as an occasional reference rather than continuous driver.
- You regularly hit Plus limits during daily development.
- You need 5x the headroom across local messages and cloud tasks.
- You want the published 5x tier without paying for Astra Ultrafast.
- You need more included usage than Pro $100.
- You have checked your account's current allowance and grandfathering eligibility.
- Do not assume a new subscription gets the previous 20x allowance.
Pro $500 ($500/mo): choose it if you need the highest included Pro usage or Astra Ultrafast. Its exact multiplier and message estimates are unpublished. Credits on Pro $100 or Pro $200 do not unlock Ultrafast.

Does every Pro $200 subscription still get the previous 20x allowance?
Pro $200 is available for new subscriptions with a lower allowance for non-grandfathered accounts; OpenAI has not published its replacement multiplier. Eligible grandfathered subscribers keep the previous allowance through October 29, 2026 while subscribed, then move to the lower allowance. Earlier published Pro 5x and Pro 20x message estimates are historical evidence, not current five-hour caps or proof of current Pro $200 entitlement. Pro $100, $200, and $500 currently have no five-hour usage limit in Work and Codex, but still have included usage allowances. Pro $500 has the highest included Pro usage and Astra Ultrafast, with no published multiplier or model-specific message estimate.
Can I buy credits on Pro $100 or Pro $200 to unlock Astra Ultrafast?
No. At launch, Astra Ultrafast is available among personal Pro plans only on Pro $500. Grandfathering Pro $200 does not add it. Pro $500 uses included usage first, then eligible credits.
Can multiple team members share a single ChatGPT Pro Codex login?
No. OpenAI's terms prohibit credential sharing. Teams needing multi-seat pooling should look at Business or Enterprise plans instead.
Do unused Pro turns roll over to the following week?
OpenAI has not published rollover behavior for unused weekly allowance. Treat each weekly window as independent unless OpenAI documentation says otherwise.
Does Pro web chat usage affect Codex CLI limits?
Standard ChatGPT web chat runs on a separate meter from Codex's agentic pool, which covers the CLI, IDE extensions, and cloud tasks.
Can I still connect an API key as a fallback on Pro?
Yes. If a workflow exhausts your Pro weekly window, the Codex CLI supports falling back to metered OpenAI Platform API billing by authenticating with an API key.
