Comparison

ChatGPT Enterprise vs Claude Enterprise

A straight comparison on price, seat minimums, contracts, admin controls, and compliance, checked against both vendors' own pages in August 2026. Plus the third option most buyers never price up.

Quick answer

Which should you buy?

ChatGPT Enterprise and Claude Enterprise are close on the fundamentals: both give every employee an AI assistant with SSO, SCIM, admin controls, audit logging, and a default of not training on your data. The practical differences are commercial. Claude Enterprise publishes its pricing at $20 per seat per month as an access fee with model usage billed separately, and is reachable at 20 seats self-serve or 50 sales-assisted. ChatGPT Enterprise does not publish pricing at all, sells on annual contracts through sales, and third-party reports put it around $45 to $75 per user per month with seat minimums in the low hundreds. Choose Claude Enterprise if you want to start smaller and see the price before you talk to anyone. Choose ChatGPT Enterprise if you want OpenAI's broader data residency regions and your company is large enough for a direct contract. The third option most buyers miss is not choosing at all: run both vendors' models behind one control plane.

Head to head

The differences that actually decide it

Checked against OpenAI's and Anthropic's published pricing, help, and support pages, August 2026. Where a vendor does not publish a figure, this table says so rather than guessing.

Fact ChatGPT Enterprise Claude Enterprise
Published pricing Not published, contact sales; reported at $45 to $75 per user / month $20 per seat / month access fee, plus model usage billed separately
Minimum seats Not published; widely reported in the low hundreds 20 self-serve, 50 sales-assisted
Contract Annual only Billed annually
Identity and access SAML SSO, SCIM, role-based access control SSO with domain capture, SCIM and just-in-time provisioning, role-based access control
Audit and compliance Compliance API, SOC 2 Type 2, ISO 27001 family Audit logs, Compliance API, customer-managed encryption keys, HIPAA-ready offering
Data residency Broad regional coverage including US, EU, UK, Japan, Canada, Australia Enterprise controls including customer-managed keys and retention settings
Training on your data Not by default Not by default
Models you can govern OpenAI models only Anthropic models only

The last row is the one buyers underweight. Whichever you pick, that vendor's admin console governs only that vendor's models, so a second provider means a second contract, console, audit trail, and bill.

Straight recommendation

Pick each one when

01

Choose ChatGPT Enterprise

Your company is large enough to negotiate a direct annual contract, you need OpenAI's specific data residency regions or Enterprise Key Management, and standardising on one vendor is a deliberate strategy rather than a default.

02

Choose Claude Enterprise

You want to see the price before you talk to sales, start at 20 seats rather than the low hundreds, and you need Anthropic's compliance surface such as customer-managed encryption keys or their HIPAA-ready offering.

03

Choose neither as your standard

Your teams want different models, your finance team wants one bill and hard caps, and you would rather not fix a year-long contract to whichever vendor is ahead this quarter. That is what a control plane is for.

The third option

Run both, govern once

We build Harriet, so treat this section as what it is. The comparison above stands on its own, and either vendor is a reasonable buy. This is simply the option that does not appear on most shortlists.

  • Both vendors' models available to your teams, plus Google and open models hosted in the EU or US, through one router.
  • One policy layer: admins choose which models each team can use, with hard budget caps per team and per user across every provider.
  • One audit trail covering every prompt, model, and dollar, with tool-level MCP controls. SOC 2 Type II certified, EU data residency available.
  • No seat minimum and no annual single-vendor commitment. Bring your own provider keys and keep the contracts you already have.

FAQ

Questions buyers ask first.

Which is cheaper, ChatGPT Enterprise or Claude Enterprise?
On published numbers, Claude Enterprise is the cheaper entry point: $20 per seat per month as an access fee, with model usage billed separately, and a 20-seat self-serve minimum. OpenAI does not publish ChatGPT Enterprise pricing; third-party reports put it at $45 to $75 per user per month with seat minimums in the low hundreds, sold on annual contracts. But per-seat price is only half the bill on either platform, because heavy users consume far more model usage than light ones. The larger cost lever on both is which model each person uses day to day, and neither vendor's console can apply that policy to the other vendor's models.
Do both keep our data private?
Yes, both state that they do not train on your business data by default, and both carry serious enterprise compliance surfaces. ChatGPT Enterprise offers SAML SSO, SCIM, a Compliance API, Enterprise Key Management, IP allowlisting, SOC 2 Type 2 and the ISO 27001 family, plus data residency across a broad set of regions. Claude Enterprise offers SSO with domain capture, SCIM and just-in-time provisioning, audit logs, a Compliance API, customer-managed encryption keys, IP allowlisting, and a HIPAA-ready offering. If a specific certification or residency region is a hard requirement, check that one item directly with the vendor, because this is the area that changes most often.
Which has the better models?
This changes every few months, which is the honest answer and also the strategic point. Both vendors ship frontier models that leapfrog each other on benchmarks and on the work your team actually does. Context windows have converged too: Anthropic's largest context is now available across paid plans rather than being an Enterprise-only perk. Committing your whole company to one vendor for a year fixes today's answer in place for a market that moves faster than the contract term.
Can we run both?
Yes, and a growing number of companies do. What you cannot do is govern both from either vendor's console: ChatGPT Enterprise administers OpenAI models, Claude Enterprise administers Anthropic models, and neither can set model policy or spending caps for the other. Running both natively means two contracts, two admin consoles, two audit trails, and two bills. A control plane like Harriet is the alternative: one dashboard that provisions and governs models from both vendors, plus Google and open models hosted in the EU or US, with per-team policies, hard budget caps, and a single audit trail.
What is the third option?
Buy neither as your company-wide standard. A control plane sits in front of the model providers and routes each team to the right model, so you keep Claude and ChatGPT available without an annual single-vendor commitment. Harriet provisions a desktop AI assistant to every employee device, lets admins decide which models each team can use, sets hard budget caps per team and per user, and audits every action down to the tool call. It starts free for up to 3 users and scales from $99 a month, with your own API keys or managed credits, and no seat minimum.
