Duke vs.
Power BI Copilot.
Bundled with your licence. Priced by capacity.
Copilot is the default because it is already in the tenant. The two things a buyer checks late: the capacity you must reserve before Copilot answers anything, and where the inference runs.
THE MATRIX
Prerequisite
POWER BI COPILOTFabric or Premium capacity, F2 and above for Copilot (Microsoft, capacity requirement lowered to F2 in January 2025)
DUKEPer-seat, no capacity to reserve
Entry cost
POWER BI COPILOTF2 capacity at 262,80 USD / month pay-as-you-go, list price, on top of per-user licences (Microsoft Fabric pricing, checked 2026-Q4)
DUKE45 EUR / user / month, Starter, no floor
Answer surface
POWER BI COPILOTSummaries and DAX generation inside a report
DUKEQuestion to certified metric, then an action, with the SQL shown
Metric governance
POWER BI COPILOTDepends on the semantic model, DAX skills required
DUKECentral semantic layer, typed, versioned, contract per metric
Inference location
POWER BI COPILOTAzure OpenAI, EU data boundary available, tenant configuration dependent (Microsoft EU Data Boundary documentation)
DUKEEU by default, Scaleway France, no non-EU model API
Isolation
POWER BI COPILOTShared multi-tenant service
DUKELogical tenant isolation, reserved GPU on the Sovereign plan
Acting on the answer
POWER BI COPILOTPower Automate, separate licence and lineage
DUKENative, governed, audit trail from source to action
VERDICT
If you already pay for Fabric capacity and only need report summaries, Copilot is the cheapest next click. Choose Duke when the number has to be defensible, the action has to happen, and inference has to stay in the EU without a tenant configuration debate.
BEST FIT
Microsoft shops whose finance or risk teams were told Copilot was free, then met the capacity invoice and the security questionnaire.
