Yes & Yes.
task.upload_artifact('test_artifact', artifact_object='foobar')
You can save a string, however please note that in the end it will be saved as a file and not a pythonic object. If you want to keep your object, you can pickle it 🙂

Alright, but is it saved as a text file or pickle file?

AgitatedDove14 Just wanted to confirm in what kind of file is the string artifact stored in? txt file or pkl file?

in case of a string and incase of an object?

Hi VexedCat68

txt file or pkl file?

If this is a string , it just stored it (not as a file, this is considered a "link")
