@esemichasnova Thank you for opening the issue. This is by-design, model alias feature is not case-sensitive. For readability, you can use hyphens instead of capital cases e.g. capital-letter-tag. We will update the documentation to make this behavior clear!

Hi, just to clarify the scenario here:

1. When we create the alias MyNewAlias via an API call, then it works fine and we see it as MyNewAlias in the MLflow frontend. When we use the API to search and list model versions' aliases, we also see MyNewAlias.

2. When we create an alias from the frontend (clicking the pencil next to the aliases box) and input MyNewAlias, we see that it is saved as mynewalias.

This seems like a bug to me.

@BalkanFlink Thank you for the additional information!

Sorry for the misinformation here. After further investigation, it turns out the alias is not case sensitive only in particular environments (e.g. Databricks, local Mac OS with file store). For other environments, the alias might be case sensitive.

We will work on fixing the UI and update you soon.
