Thanks for reaching out to us, I think you are mentioning - Transform and Shape data: bring the AI insight to Power BI report. I don't think you can use your own model in this function.
The services that are supported today are the following:
Sentiment Analysis
Key Phrase Extraction
Language Detection
Image Tagging.
If that's what you want, the next step for you is to invoke Vision Function in Power Query as below guidance:
