A catalog of AI models in Microsoft Foundry that you can discover, compare, and deploy using Azure’s built‑in tools for evaluation, fine‑tuning, and inference
Hello @LAURI HOWARD ,
Welcome to Microsoft Q&A .Thank you for reaching out to us.
Error code 715-123420 is a generic deployment failure message and the exact cause is not documented in the provided references. However, based on the documented failure modes for Foundry model deployments and partner/Marketplace models, the most likely categories are:
- Subscription eligibility / model availability
- Third‑party and some first‑party models can be blocked at the subscription or region level even when the portal UI allows starting the flow.
- For partner models (like Anthropic Claude), common blocking reasons include:
- Offer not available for the subscription’s billing country/region.
- Marketplace purchase eligibility checks failing.
- Model not available in the selected region.
- For Azure‑offered models (like GPT o4‑mini), deployment can fail if the model is not available to that subscription or region.
- The documented guidance for “Model not available” is to list available models and regions for the subscription and resource:
- Run
az cognitiveservices account list-modelsagainst the Foundry resource to confirm which SKUs and regions are actually deployable for that subscription.
- Marketplace access / billing account region
- For partner and community models, the Marketplace layer can reject the deployment even when the terms page opens. Documented Marketplace‑related errors include:
- Offer not available in your country/region.
- Marketplace purchase eligibility check failed.
- Unable to create a model deployment because Azure Marketplace rejected the subscription request.
- These are tied to:
- The billing country/region of the subscription.
- Provider’s allowed countries/regions for that specific SKU.
- Marketplace purchase eligibility for the subscription type.
- CSP subscriptions are explicitly unsupported for third‑party offerings, but an Azure Plan / Pay‑As‑You‑Go subscription can still be blocked if the billing region is not allowed for that SKU.
- Quota or capacity
- For Foundry model deployments, quota issues are a documented cause of deployment failure:
- “Quota exceeded” when the subscription has reached deployment quota for the selected SKU or region.
- Recommended action is to check quotas in the Foundry portal or request an increase through Azure support.
- For Claude specifically, rate‑limit and quota issues are documented at the API level (HTTP 429), but deployment‑time quota exhaustion can also surface as a generic deployment error.
- Permissions / RBAC
- For model deployments via CLI/Bicep, “Authorization failed” occurs when the identity does not have the required RBAC role; the fix is to assign the Cognitive Services Contributor role on the Foundry resource.
- In this case, the subscription role is Owner, which normally implies sufficient permissions, so RBAC is less likely to be the root cause.
- Backend or transient platform issues
- The references include multiple examples where:
- A deployment error was ultimately resolved by changing region, indicating undocumented region‑specific capacity or configuration issues.
- A Foundry publishing error (“Value cannot be null. (TenantId)”) was fixed by a backend hotfix from the product group.
- A Claude deployment that was stuck with “API deployment for the resource is not ready” was resolved only by deleting and recreating the deployment later.
- These patterns indicate that some opaque error codes are caused by backend issues or transient platform faults that require either:
- Retrying the deployment (sometimes after deleting and recreating), or
- Direct intervention from Azure support / product group
These combination of checks will distinguish between:
- Subscription/model availability or Marketplace eligibility issues (models not listed or region/country unsupported), and
- A backend/platform issue (models listed and apparently eligible, but deployments still fail with 715‑123420), which then requires Azure support or a product hotfix.
