Cost: Azure Local Foundry
Scope
This is the cost page for Azure Local Foundry, one of the three targets in ADR-0011. Compare all three targets on the Deployment targets hub.
This target has not been built yet
Nothing on this target has been deployed from this repository, and no automation exists for it yet. Everything below is drawn from accepted decisions and first-party research. Treat it as a design, not an as-built record.
What is decided today
Fixed cost, billed per physical core of the Azure Local host per day, whether or not you infer.
The rates are confirmed from the Microsoft retail prices API, retrieved 2026-07-30 (SPIKE-26):
Tier USD per physical core per day Approx. per 30-day month L1 0.33 9.90 L2 0.667 20.01 Disconnected operations 1.67 50.10 The Windows Server guest add-on is 23.30 USD per physical core per month.
Azure Hybrid Benefit is not a discount. It is a separate SKU rated 0.00 that waives the host fee and the guest subscription together, and it applies to L1 only.
There is no per-token inference charge.
ADR-0006's layer 1 spend guard has no referent here. The fee is set by core count and does not move with usage, so there is no metered call for a budget rule to bind. Only the subscription spending limit transfers.
Billing continues for 31 days after disconnection unless the ARM resource is deleted, so a decommission step is a real cost control, not hygiene.
