Azure AI Custom Vision Azure Machine Learning AutoML for Images & Microsoft Foundry (Custom Vision Migration)
Legacy names Azure AI Custom Vision, Azure Cognitive Services Custom Vision
Custom image classification and object detection model training and inference transitioning from the retiring Azure AI Custom Vision service to Azure Machine Learning AutoML for Images and Microsoft Foundry multimodal models.
Naming timeline
- Azure Cognitive Services Custom Vision
Launched as a no-code portal and REST API for training custom image classifiers and object detectors with small labeled datasets.
- Azure AI Custom Vision
Rebranded from Azure Cognitive Services Custom Vision to Azure AI Custom Vision.
- Azure Machine Learning AutoML for Images & Microsoft Foundry (Custom Vision Migration)Current name
Microsoft announced the planned retirement of Azure Custom Vision on September 25, 2028, directing workloads to Azure Machine Learning AutoML for Images, Microsoft Foundry vision models, and Azure Content Understanding.
What replaced Azure AI Custom Vision?
Azure AI Custom Vision has been superseded by Azure Machine Learning AutoML for Images & Microsoft Foundry (Custom Vision Migration), with the latest change on 25 September 2025 (Retirement Announcement (EOS September 25, 2028)). Earlier names covered by this entry also include Azure Cognitive Services Custom Vision. Custom image classification and object detection model training and inference transitioning from the retiring Azure AI Custom Vision service to Azure Machine Learning AutoML for Images and Microsoft Foundry multimodal models. The underlying legacy API or CLI surface is deprecated, so a technical migration is required.
Also known as
- Custom Vision Service
- CustomVision.Training
- CustomVision.Prediction
- Azure Content Understanding
Technical identifiers
Legacy identifiers deprecated. The underlying API or CLI surface for the legacy name is officially deprecated, so this change requires a technical migration rather than a label update.
| ARM Resource Providers (Microsoft.*) | Microsoft.MachineLearningServices/workspaces Microsoft.CognitiveServices/accounts (kind: CustomVision.Training - Deprecated) Microsoft.CognitiveServices/accounts (kind: CustomVision.Prediction - Deprecated) |

Microsoft.CognitiveServices/accounts kinds 'CustomVision.Training' and 'CustomVision.Prediction' and Custom Vision Training/Prediction REST APIs retire on September 25, 2028 in favor of Azure Machine Learning AutoML (Microsoft.MachineLearningServices/workspaces) and Microsoft Foundry.
Notes & disambiguation
- Originally launched in preview at Microsoft Build 2017 as Microsoft Custom Vision Service (GA 2018 as Azure Cognitive Services Custom Vision) and rebranded to Azure AI Custom Vision in July 2023, the service was announced for retirement in September 2025 with full support continuing until September 25, 2028, after which API calls to Custom Vision will fail.
- Official Microsoft migration guidance directs customers building traditional supervised image classification and object detection models to Azure Machine Learning AutoML for Images (via Azure ML studio UI, Python SDK v2 automl.image_classification / automl.image_object_detection, or CLI v2), and directs generative/zero-shot classification workloads to Microsoft Foundry multimodal models and Azure Content Understanding in Foundry Tools.
- Legacy ARM resources under Microsoft.CognitiveServices/accounts with kinds 'CustomVision.Training' and 'CustomVision.Prediction' and the Microsoft.Azure.CognitiveServices.Vision.CustomVision SDKs are deprecated and scheduled for retirement on September 25, 2028 in favor of Microsoft.MachineLearningServices/workspaces (az ml job create) and Microsoft Foundry endpoints.
