What Microsoft's own reports count as "active," what the widely cited 20-30 percent figure actually measures, and why it likely understates the gap rather than overstates it. - [![](https://bitvaria.com/_astro/ki-kosten.5JN_PA3U.jpeg)](https://bitvaria.com/en/was-kostet-ki-projekt-mittelstand/) 24\.

What Would a Replacement Need?](https://bitvaria.com/en/copilot-ist-in-office-integriert/) "Integrated" means four things: where the button sits, the data, the permissions and the operation. A replacement only has to cover the parts people actually use. Where to ask, you can look up. - [![](https://bitvaria.com/_astro/was-ein-wechsel-wirklich-kostet.C88xgewM.jpg)](https://bitvaria.com/en/was-ein-wechsel-wirklich-kostet/) 2\. Okt. 2026 6 min read ## [What Switching AI Solutions Really Costs](https://bitvaria.com/en/was-ein-wechsel-wirklich-kostet/) The simple switching calculation compares a price per user with a price per token. Those are two different things. An honest calculation has five cost blocks and no fixed saving. - [![](https://bitvaria.com/_astro/ist-das-modell-aus-china-ein-problem.Dpppcpzz.jpg)](https://bitvaria.com/en/ist-das-modell-aus-china-ein-problem/) 1\. Okt. 2026 10 min read ## [Is an AI Model from China a Problem?](https://bitvaria.com/en/ist-das-modell-aus-china-ein-problem/) The question hides three different questions: where the data goes, how the model behaves, and what the company allows. Only the first one is settled by where the model runs. - [![](https://bitvaria.com/_astro/was-das-admin-center-zeigt.aQisU7K1.jpg)](https://bitvaria.com/en/was-das-admin-center-zeigt/) 4\.

Each number needs context: what was recorded, and what was calculated from a formula? - [![](https://bitvaria.com/_astro/anteil-ki-aufgaben-teuerstes-modell.0pfQPelZ.jpg)](https://bitvaria.com/en/anteil-ki-aufgaben-teuerstes-modell/) 20\.

The exact share is not the interesting number. What is interesting is that someone measured it at all. - [![](https://bitvaria.com/_astro/qualitaetsluecke-offener-modelle.DHkMttWi.jpg)](https://bitvaria.com/en/qualitaetsluecke-offener-modelle/) 14\.

Why the average number is still almost irrelevant for your own decision. - [![](https://bitvaria.com/_astro/ki-modelle-hosten-oder-mieten.DCbdN9Pz.jpg)](https://bitvaria.com/en/ki-modelle-hosten-oder-mieten/) 30\.

The Honest Math](https://bitvaria.com/en/ki-modelle-hosten-oder-mieten/) Is your own server for open AI models worth it, or is a subscription cheaper?
