Discrepancies in installing aml sdk v2 (azure-ai-ml module)

The article - https://learn.microsoft.com/en-us/python/api/overview/azure/ml/installv2?view=azure-ml-py suggests that we need to install aml python SDK v2 using the command:
pip install --pre azure-ai-ml

However, https://learn.microsoft.com/en-us/azure/machine-learning/tutorial-auto-train-image-models?tabs=python says you can install using the following command:

pip install azure-ai-ml

We have inconsistencies in the installation instructions between two articles, and there might be more. Please have consistent installation instructions in all articles.
