Hi Thanks for that. 
So, yea, i went to the azure cost management section and am exporting the costs. However, the newly added serverless budget tags are not appearing in the exports. 
Neither are they appearing on the dashboard. I've tried filtering the dashboard on the tags.
Oddly, of the billing origin product, "model serving" is filtering through, but "vector search" and "apps" are not. 
As in i can see model serving in azure cost management, but not vector search or apps.

Cheers
