ChatGPT, Claude or Gemini for Your Company? The Honest 2026 Comparison

The question now comes up in every management meeting: employees are using AI anyway - so which tool do they get officially? ChatGPT, Claude or Gemini? The answers you find online compare benchmarks. The answer a mid-sized company needs is a different one: it is about tiers, administration, data protection and the ecosystem your firm already lives in.

The honest summary first: the gap between the three models flips every few months; the billing and contract situation does not. Anyone choosing a platform today based on the last benchmark is buying a snapshot.

In short: The business tiers cost almost the same - ChatGPT Business and Claude Team each run 20 US dollars per seat per month billed annually, while Gemini is included in Google Workspace tiers at no surcharge (as of October 2026). All three exclude training on your data at these tiers and ship admin consoles. The real decision is the ecosystem: Workspace firms take Gemini, anyone working a lot with long documents takes Claude, and anyone who already knows ChatGPT stays with ChatGPT. More important than the platform are two rules: no personal accounts for company data, and an automated process belongs on the API, not in the chat.

What do the three providers' business tiers cost?

Entry prices for managed company accounts, as of October 2026:

Sources: OpenAI pricing, Anthropic pricing, Google Workspace pricing, each as of October 2026. For Germany, Google shows only euro prices (Business Starter 6.80 euros, Business Standard 13.60 euros per user per month with a one-year commitment), OpenAI a euro amount alongside the dollar price. Anthropic lists US-dollar prices only, which by its own account apply to US customers; price and currency may differ by region. Anthropic and Google state their prices excluding tax; OpenAI's pricing page says nothing on the matter.

For a 20-person team that means list prices of 400 US dollars a month on ChatGPT or Claude, or 500 US dollars billed monthly - with Gemini the AI is included in the existing Workspace licence at no extra charge. Enterprise levels with extended security and data options carry custom pricing at OpenAI and Google; Anthropic lists Claude Enterprise at 20 US dollars per seat per month billed annually plus usage at API rates. And for Microsoft shops there is the fourth option: the add-on Microsoft 365 Copilot Business, for companies with up to 300 users, has a regular price of 21 US dollars per user per month paid yearly and works directly inside Outlook, Word and Excel, and inside Teams with a Teams licence.

Where do the three platforms really differ?

The answer quality of the current models sits close together for office work - and the order flips with every model generation. What does not rotate every three months are three structural questions.

First, the ecosystem. Gemini lives inside Gmail and, from Business Standard, also inside Docs and Drive - for Workspace firms adoption is at most a tier change, not a new tool. ChatGPT Business and Claude Team both ship ready-made connectors to the major workplace systems, including Google Workspace, Microsoft 365, Slack and GitHub, and both offer shared projects for joint work-in-progress. Claude is strongest where long documents must be read in one pass: on the Team plan its context window holds up to one million tokens depending on the model, against up to 256,000 on ChatGPT Business.

Second, administration: all three business tiers ship an admin console, SSO integration and usage overviews - the differences lie in the detail of logging and data locations, not in whether they exist. Third, the outlook: whoever picks a tier today also buys its model roadmap. All three providers ship several generations per year; the platform is the constant, the model the replaceable part.

What does this mean for data protection and compliance?

The most important line is not the model name but the tier. In the business and enterprise levels all three providers contractually exclude training on your inputs - on free and personal accounts, inputs may be used for training depending on provider and opt-out status. An employee pasting customer data into a personal ChatGPT window creates a data transfer without a contract - regardless of how good the model is.

OpenAI, Anthropic and Google are US groups, but for customers in Germany the contracting parties are their Irish entities. Deployment runs through their data processing agreement, and the providers cover transfers to the US through EU standard contractual clauses or an adequacy decision. On EU data residency the three differ markedly: OpenAI offers it for ChatGPT starting with the Enterprise plan and for the API on request, Google can keep data at rest in Europe from Business Standard upward, and Anthropic states that data for its commercial products is stored in the US. Check this before signing. The remaining duties are homemade: the AI competence requirement under Article 4 of the AI Act requires measures that support the development of users' AI literacy (documented instruction, for example), and the rules for permitted data belong in the AI policy for employees - both apply regardless of the platform choice.

When do licences not solve the task?

A chat seat answers the question of what your people write, review and research with. It does not answer what your processes run on: an agent that processes invoices or qualifies customer enquiries attaches the models via API - billed per token used, embedded in your own software, with no human operating a chat.

The two decisions get mixed up in practice all the time. Anyone building a workflow for the inbox needs no fifty seats but an API and a home for the workflow - we did the maths on the tooling question behind that in the comparison of Zapier, Make, n8n and the custom AI agent. Conversely, no agent, however good, answers which chat the workforce may use.

Which platform fits whom?

The honest decision aid has four outcomes:

• Gemini if your company runs on Google Workspace: the AI is already in the tier, in Gmail and from Business Standard also in Docs, Sheets and Drive, and needs no second system.
• ChatGPT Business if your team already knows ChatGPT and should stay with it. ChatGPT and Claude ship connectors to the major workplace systems alike.
• Claude Team if the focus is on long documents - typical for law firms, consultancies and engineering.
• Microsoft 365 Copilot if you live in the Microsoft world anyway: the add-on works in Outlook and Word, and in Teams with a Teams licence, and saves the platform switch.

Those unsure tend to try the wrong order: test the platform first, write the rules later. The right way round works differently - the rules for permitted data precede the tier choice, and the organisational duties of a managing director during rollout are written up in the AI guide for managing directors and CEOs.

Conclusion: choose the platform, rules first

The comparison ends less spectacularly than the headlines promise: for office work, the three platforms differ mainly in ecosystem, not intelligence - and the dividing line runs between personal account and company licence, not between the models. Whoever has formalised this - one tier, one processing agreement, one page of rules - has made the actual decision. Which of the three names sits on the licence is nearly a matter of taste.

When the next step goes beyond the chat licence - for example an agent carrying a real process - our page on AI automation for companies describes what a first bounded workflow with a legal framework looks like.

This article was published on 21 September 2026. On 14 October 2026 we corrected statements that were already wrong at publication: ChatGPT Business and Claude Team cost 20 rather than 25 US dollars per seat per month billed annually and 25 rather than 30 US dollars billed monthly, Claude Team is available for two to 150 seats rather than from five, Anthropic lists a price for Claude Enterprise, for smaller companies Microsoft offers the cheaper Copilot Business add-on, and Article 4 of the AI Act requires measures that support users' AI literacy, not demonstrably trained users. We also made the statements on Gemini features per Workspace plan, contracting parties and data locations, API billing, the training exclusion on Claude Team and Copilot in Teams (only with a Teams licence) more precise. We removed unsupported claims that ChatGPT has the widest choice of connectors and the widest adoption and that Claude has the cleanest team space and a more careful answer style. The context window comparison is new.
