Quick answer
Mistral’s generally available Regional Endpoints let customers choose eligible inference processing in the EU or US. They do not make the entire Mistral service, account, billing, or analytics control plane regional.
Use api.eu.mistral.ai for eligible EU processing and api.us.mistral.ai for eligible US processing. Mistral documents a 1.1× list-price multiplier for regional input, output, cache reads, and cache writes.
What is localized
The selected regional base URL routes supported model execution and associated inference input/output processing to infrastructure in that geography. Mistral’s announcement notes limited safeguarded transfers to sub-processors may still occur outside the region under its Trust Center disclosures.
The endpoint is the source of truth for inference geography. Log its hostname, the SDK server value, model ID, timestamp, and response request identifier for every regional call.
What is not localized
Mistral says regional inference does not provide regional storage for all control-plane data. Account configuration, API keys, billing, access management, usage analytics, and other operational metadata may be handled outside the selected inference geography.
This means “EU inference” is narrower than “all service data remains in the EU.” Map every data class and processor before making a residency claim.
Region, retention, and downstream systems
Regional inference controls where eligible processing happens. Zero data retention controls whether eligible request and response content persists after processing. They are separate controls.
Also review proxies, gateways, logs, observability, file stores, caches, tool destinations, support systems, and application databases. A regional model call cannot regionalize downstream systems that send or store the result elsewhere.
For feature exclusions, read the Agents, Batch, and Files guide. For endpoint selection, compare regional versus global inference and use the readiness checker.
Frequently asked questions
What do Mistral Regional Endpoints regionalize?
Eligible inference inputs, outputs, and processing run in the selected EU or US geography, subject to the provider’s documented limited safeguarded sub-processor transfers.
Does a regional endpoint regionalize the Mistral control plane?
No. Mistral says account configuration, API keys, billing, access management, usage analytics, and other operational metadata may be handled outside the inference geography.
Is regional inference the same as zero data retention?
No. Region controls where eligible inference is processed; ZDR controls eligible content retention after processing. A workload may require both.
