2026 comparison
Microsoft Copilot vs ChatGPT: which to choose for the enterprise?
Both run on the same technology: OpenAI's models. The real difference lies elsewhere: in integration, governance and the bill.
The difference in one sentence
Copilot and ChatGPT: what's the real difference?
Microsoft 365 Copilot is ChatGPT built into your Office tools (Word, Excel, Teams, Outlook), with your tenant's data. ChatGPT Enterprise is a standalone interface, independent of Microsoft. Same model family, two usage logics, and two ways of being locked in with the same provider.
Strengths & limits
What each does best
Microsoft Copilot's strengths
Native integration with the Office suite: no change in habits, fast adoption, access to the context of your company documents. Copilot is billed per user per month, on top of your Microsoft 365 licenses.
ChatGPT Enterprise's strengths
A richer interface that evolves faster, independent of the Microsoft ecosystem, with OpenAI's features first. The flip side: it's one more tool to administer, and still a single model provider.

The real issue
The criterion CIOs underestimate: reversibility
Both Copilot and ChatGPT Enterprise tie you to OpenAI. If another model becomes better or cheaper (which happens regularly) you can't benefit from it without changing tool, contract and habits.
The Lamalo answer
Lamalo absorbs the dependency risk
An orchestration platform brings new models into the console without changing anything for your teams. Lamalo (formerly Spoton), built in Strasbourg, brings together ChatGPT, Claude, Gemini, Mistral and +200 models, with automatic routing, an audit log, team-level policies and European hosting. Sovereignty is on demand: you activate advanced sovereignty as an option on your sensitive uses only, without paying for it across the whole company. From €15/mo excl. VAT.
Frequently asked questions
FAQ
Does Copilot use ChatGPT?
Yes. Microsoft 365 Copilot relies on OpenAI's models, the same family as ChatGPT, hosted on Microsoft's Azure infrastructure.
Is Copilot GDPR-compliant?
Microsoft offers GDPR commitments and a DPA. The concern for a European company isn't GDPR but exposure to the Cloud Act, since hosting falls under US law.
Can you keep Copilot and add a sovereign platform?
Yes, and it's a common scenario: Copilot for day-to-day office work, a sovereign platform for sensitive uses and multi-model needs.
What's the European alternative to Copilot?
Lamalo is a French orchestration platform that gives access to the same cutting-edge models, with EU hosting, an audit log and a no-training commitment, from €15/mo excl. VAT.
