ChatGPT subscription or OpenAI API: what should a company buy?
Short answer
A ChatGPT subscription gives employees a ready workspace, and the OpenAI API lets you use the models inside a company process. Ten Business Standard seats cost $250 a month. An API app at 10,000 calls costs $90 in tokens, but with a server and a €3,000 build spread over 24 months it comes to about €211 a month. A company often needs both paths.
- net per day of closed training for the team
- from €1,150
- people in one training group
- up to 15
- after this time, we measure the effect on the same tasks
- 30 days

ChatGPT and the API in companies: statistics 2026
€211
a month is what an API app costs at 10,000 calls, with a server and the build spread over 24 months. Ten ChatGPT Business seats cost €223. Scenario.
40%
According to Menlo Ventures (2025), Anthropic holds 40% of large companies' spending on language model APIs and OpenAI 27%, based on a survey of about 500 US decision makers.

What you get on each path
| Question | ChatGPT on a business plan | Integration through the API |
|---|---|---|
| Where the work happens | In the ChatGPT workspace | In the company's app or process |
| How the data arrives | Through the user and connections | Through integrations built for the process |
| Who sets the order of steps | The user | The app's logic and the process rules |
| What you pay the vendor for | Seats and extra usage | Use of the models and tools |
| What you maintain | Accounts, configuration, materials | Also code, a server, monitoring and errors |
ChatGPT has connections to sources and multi-step features, so not every automation needs a separate app. The scope is described in the ChatGPT Work documentation.
Case 1: the team prepares analyses and materials
An employee picks the task, judges the sources and corrects the result. A company ChatGPT gives a shared way of working and managed accounts. Preparing materials, rules and training is the biggest part of the rollout.
Ten Business Standard seats cost $250 a month, or $2,400 a year. The rates are $25, or $20 a month with annual billing, with at least two paid seats (Business FAQ). The next steps are described in the ChatGPT Business rollout plan.
Case 2: every request follows the same path
The company reads requests from a form, assigns a category, checks completeness and passes cases to the CRM, and some go to a person with the reason they were stopped. Its own integration gives control over the queue, the permissions and the retries.
- GPT-6.1 Sol tokens
- 20 million × $2 + 5 million × $10 = $90 (€80)
- Hetzner CX23 server
- €5.49
- A €3,000 build spread over 24 months
- €125
Total about €211 a month, before maintenance and checking results
One call: 2,000 input tokens and 500 output tokens, no cache and no retries. Rates from the OpenAI API price list, the server at Hetzner's price list from 15 June 2026. Converted at the ECB rate of 1.1205 USD per euro on 22 October 2026. The 24-month period is the scenario's assumption.
The GPT-6.1 Sol rates come from the OpenAI API price list. The token bill is no quote for a finished system: the interface, roles, recovering failed tasks and monitoring need a supplier. The full scope is described in OpenAI API implementation.
Which path fits the task
An employee picks the files and corrects the result
ChatGPT Business
$25 a seat
The task starts after an event in a system
integration through the API
from €3,000
New problems plus a repeatable process
both paths
separate bills and limits
The simplest test is to ask who presses the button. If a person starts the task and then judges the result, the ready workspace is usually enough and no panel needs building. If a form, an email or a change in the CRM starts the task, and the result has to land in another system without retyping, you need an integration. In many companies the answer is both, because people need accounts and a repeatable process needs an integration.
Will the API replace ChatGPT accounts for less
Comparing $250 for 10 accounts with $90 for tokens sets two different ways of working side by side and gives no basis for promising a $160 saving. An app that replaces ChatGPT has to have sign-in, files, history and access to data. Compare solutions with the same scope, in one currency, at a stated rate.
When to combine both paths
ChatGPT
new problems
A salesperson prepares a non-standard proposal and analyses an unusual enquiry.
API
a repeatable process
The app sorts the data from every new enquiry and saves it in the CRM.
Shared
one source of truth
Agreed data sources and one place of approval, so two versions of a quote do not appear.
Control billing and limits separately for the ChatGPT workspace and the API project. Setting up a Business workspace is described under ChatGPT rollout for your team: from €1,150 net for a team of up to 10 people, with a measurement after 30 days. An API app is a separate project from €3,000 net. For the first call, prepare the number of users, the monthly volume and the system where the result should land.
