Rate limits
The following rate limits apply to evaluation runs:
| Limit | Value |
|---|---|
| Maximum size per row | 2 MB |
| Maximum rows per batch evaluation | 100,000 |
Evaluation run creations are rate-limited at the tenant, subscription, and project levels. If you exceed the limit:
- The response includes a
retry-afterheader with the wait time. - The response body contains rate limit details.
Use exponential backoff when retrying failed requests.
Virtual network support for evaluation
For network isolation, you can bring your own virtual network for evaluation. To learn more, see How to configure a private link.
Virtual network support for evaluation requires network injection (subnet delegation), but if you only need evaluation capabilities and do not require full agent support (Cosmos DB, AI Search, or project capability host), consider using the simplified evaluation-only setup template (15a) instead. It deploys a minimal network-secured environment tailored for evaluation scenarios with fewer resources and reduced complexity.
Note
If you connect Application Insights, evaluation data is sent to it.
Important
To prevent evaluation and red teaming run failures, assign the Foundry User role to the project's Managed Identity during initial project setup.
Important
The Foundry RBAC roles were recently renamed. Foundry User, Foundry Owner, Foundry Account Owner, and Foundry Project Manager were previously named Azure AI User, Azure AI Owner, Azure AI Account Owner, and Azure AI Project Manager. You might still see the previous names in some places while the rename rolls out. The role IDs and core permissions are unchanged by the rename.
Virtual network region support
Bringing your own virtual network for evaluation is supported in all regions except:
- Central India
- East Asia
- North Europe
- Qatar Central
Bring your own storage
You can use your own storage account to run evaluations.
You can either use a Bicep template or manually create and provision access to your storage account in the Azure portal. To use a Bicep template, follow these steps.
- Create and connect your storage account to your Foundry project at the resource level. You can use a Bicep template, which provisions and connects a storage account to your Foundry project with key authentication.
- Make sure the connected storage account has access to all projects.
- If you connected your storage account by using Microsoft Entra ID, make sure to give managed identity Storage Blob Data Owner permissions to both your account and the Foundry project resource in the Azure portal.
