Codex Business vs Pro (2026): Usage, Price and Who Should Buy Which
Codex on ChatGPT Business vs Pro: per-seat vs personal price, Codex usage limits, credits, data and admin controls, and which one a solo dev or team should buy.
8 min read
Business seat prices and rules checked Oct 30, 2026 in OpenAI’s ChatGPT Business help article. Pro tiers checked Oct 29, 2026 in OpenAI’s Pro plans help article. Codex limits, Business features and plan cards checked Nov 1, 2026 on Codex pricing, and Codex credits and access on Nov 1, 2026 in the Codex plan help article. All prices are US dollars before tax. Every source is listed at the bottom. No affiliate links on this page (how we work).
Here’s the finding that decides most of these: “no five-hour limit” is on both sides. OpenAI says “Pro plans currently have no five-hour limit” on Codex pricing (verified Nov 1, 2026). It says a Business Premium seat includes “higher usage for ChatGPT Work and Codex than Standard seats, no five-hour usage limit” (verified Oct 30, 2026). A Standard Business seat doesn’t get that. It gets the same five-hour estimates as Plus. So the real fight isn’t Business vs Pro. It’s Business Premium vs Pro, and the difference is billing, admin and data terms, not a published usage number.
TL;DR by situation
- Solo heavy Codex user, no company paperwork: Pro. Pro 100 is $100 a month for one person with no five-hour limit. The cheapest Business setup with a Premium seat is one Premium plus one Standard ($120 a month on annual billing, $150 monthly), because Business needs two seats.
- Team of 3 or more: Business. Give Standard seats to most people and Premium seats to whoever lives in Codex. Pro is a personal plan, and you can’t pool it or manage it centrally.
- You need SSO, MFA or no training on your data by default: Business. Those terms are on the Business pages. I didn’t find them on the Pro pages I read.
- You want Ultrafast mode: Pro 500, the only plan that has it per OpenAI’s Pro help (verified Oct 29, 2026).
Plan table
| Plan | Price | Billing | Codex usage | Credits |
|---|---|---|---|---|
| Pro 100 | $100/mo | Monthly only | No 5-hour limit | Buy more |
| Pro 200 | $200/mo | Monthly only | More than Pro 100 | Buy more |
| Pro 500 | $500/mo | Monthly only | Highest Pro | Buy more |
| Business Std | $25 or $20/seat | Monthly or annual | Same as Plus | Workspace |
| Business Prem | $125 or $100/seat | Monthly or annual | No 5-hour limit | Workspace |
Business: Standard “$25 per user per month” or “$20 per user per month, billed annually”; Premium “$125 per user per month when billed monthly” or “$100 per user per month when billed annually”; “A Business workspace requires at least 2 Standard or Premium seats in total: 2 of either type, or 1 of each”; “pricing may vary depending on your country and currency type” (Business help, verified Oct 30, 2026). Pro: $100, $200, $500 a month; “Pro 200 includes more usage than Pro 100. Pro 500 offers the highest included usage”; billed monthly, no annual (Pro help, verified Oct 29, 2026; Codex pricing, verified Nov 1, 2026). Full plan list: Codex pricing.
Usage limits: what OpenAI publishes
Standard Business = Plus. Codex pricing lists the same local-message estimates per five hours for Plus and Standard Business: GPT-6.1 Terra 35–285, GPT-6.1 Sol 15–160, GPT-6 Sol 15–150, GPT-6 Astra 5–45 and GPT-6 Luna 350–3,000 (verified Nov 1, 2026). OpenAI adds that “These estimates are not fixed message limits”, that “Cloud tasks may use more of your allowance than local messages”, and that “Weekly limits may also apply.”
Pro and Premium: no five-hour limit, weekly size unpublished. Neither Pro nor a Premium seat has a published five-hour cap, and OpenAI doesn’t publish the weekly allowance for either. For Premium, OpenAI says only “higher usage” than Standard, with no multiplier. For Pro, it says the three tiers step up, with no numbers. So anyone telling you “Premium equals Pro 200” is guessing. I couldn’t find a published head-to-head, and I’m not going to invent one.
One recent change that stings. Pro 200 subscribers who joined Sep 22–29, 2026 kept an older, larger allowance “through October 29, 2026”. After that date they moved to the lower allowance at the same $200 (Pro help, verified Oct 29, 2026). Same price, less usage. It’s a Shark Tank counteroffer nobody asked for: same valuation, smaller check. I’m out.
Both sides can buy more. “Eligible Plus and Pro users can buy credits without changing plans” (Codex help, verified Nov 1, 2026). Business uses flexible pricing: the workspace buys credits beyond included limits (Business help, verified Oct 30, 2026). OpenAI doesn’t publish a per-credit price for either. More on how credits work in Codex credits, and on limits in general in Codex usage limits.
Where you can run it. Codex Cloud is available on “eligible Plus, all Pro tiers, Business, Enterprise” and Edu accounts (Codex help, verified Nov 1, 2026). Business cloud chats get “larger VMs” per Codex pricing (verified Oct 30, 2026). GPT-6.1 Terra is listed for Plus, Pro, Business, Enterprise and Edu (Codex pricing, verified Nov 1, 2026).
Data, admin and privacy
This is where Business earns its name. From Codex pricing (verified Oct 30, 2026) and the Business help article (verified Oct 30, 2026):
- No training by default. Codex pricing: “No training on your business data by default”. The help article: “OpenAI won’t train on your workspace’s data.”
- Workspace and login controls. “A secure, dedicated workspace with essential admin controls, SAML SSO, and MFA.”
- Codex-specific admin. The Business column of the Codex feature grid includes cloud-managed config policies and Codex access tokens, plus GitHub code review and Slack and Linear integrations.
- Seats move. Business seats can be assigned and reassigned. When someone leaves, the seat stays with the company.
- What Business doesn’t have. RBAC and custom roles, SCIM, EKM, domain verification, data retention and residency controls, the analytics dashboard, and the Compliance API with audit logs are Enterprise-only on Codex pricing.
- No API included. Business “does not include API usage”. Neither does Pro.
Pro is a personal subscription. It’s tied to one person’s account, and none of the workspace controls above appear on the Pro pages I read. If your company’s security review asks “who owns the account and can we turn off training”, Pro has no answer to give. Business does.
Seat math (listed prices only)
Business always needs two seats, so the per-person price depends on who fills them. Arithmetic on the listed prices:
| Setup | Per month | Billing |
|---|---|---|
| Pro 100, one person | $100 | Monthly |
| 1 Premium + 1 Standard | $120 | Annual |
| 1 Premium + 1 Standard | $150 | Monthly |
| 2 Premium | $200 | Annual |
| Pro 200, one person | $200 | Monthly |
| 5 Standard | $100 | Annual |
| 4 Standard + 1 Premium | $180 | Annual |
What jumps out:
- For one person, Pro 100 is the cheapest way to get no five-hour limit. The Business route costs at least $20 a month more, because of the second seat.
- Two heavy users: two Premium seats on annual billing cost $200 a month together, the same as one Pro 200. Two Pro 100s also cost $200. If both of you need it, Business gives each person no five-hour limit plus admin and data terms for the same money. You do commit to a year, though.
- A five-person team with one Codex power user: 4 Standard + 1 Premium is $180 a month on annual billing. Five Pro 100s would be $500.
Please don’t read the fine print the way the market read mortgage bonds in The Big Short. The Jenga tower here is the usage nobody published: you can compare prices to the dollar, but not allowances.
Here’s what I’d do
On my own with no employer rules: Pro 100. It’s the cheapest way to get no five-hour limit, it’s month to month, and if I outgrow it, Pro 200 is one click away. On a team of three or more: Business, mostly Standard seats, Premium for the one or two people who hit limits, on annual billing if you’re sure about the year. If a client contract mentions SSO or training on data, Business is the only one of the two that prints those terms. Coming from Plus? Read Codex Plus vs Business and Codex Pro vs Plus first, since a Standard Business seat won’t raise your Codex limits over Plus. Shopping beyond OpenAI? AI coding tools compared has dated prices.
If your company needs more admin and data controls, Codex Business vs Enterprise covers when Enterprise is worth it.
