Important

Support for Machine Learning Studio (classic) will end on 31 August 2024. We recommend you transition to Azure Machine Learning by that date.

Beginning 1 December 2021, you will not be able to create new Machine Learning Studio (classic) resources. Through 31 August 2024, you can continue to use the existing Machine Learning Studio (classic) resources.

ML Studio (classic) documentation is being retired and may not be updated in the future.

Tip

Customers currently using or evaluating Machine Learning Studio (classic) are encouraged to try Azure Machine Learning designer, which provides drag-n-drop ML modules plus scalability, version control, and enterprise security.
