How to track which model was used to create a vector from Firefly Web

Hi there

I’ve been working on a project for a client - that features 20+ vector characters created using FF. As part of our due-diligence process, we need to show that all AI outputs are from FF-only models (ie those that are commercially safe).

For those we generated in Illustrator, these are easily trackable.

BUT there are a small amount that were generated using the web version of FF text-to-vector.

The problem is:

1. These images show up in the Illustrator document with the Spark icon (indicating a Generative Image) - but do not show what model was used (in the Properties or Generation History panel).
2. We need to show our client that ALL generations were done using FF’s commercially-safe models, and not 3rd party models.
3. Is there any way or resource we can use to verify that only FF models were used?
4. And no, they don’t show up in the Web version’s “your stuff” folder

I find it strange that Illustrator can recognise that the vector is a Generative one, but not show the model used.

Additionally, I can find any way to access the metadata or Content Credentials for these.

Any help appreciated!
