Why would you be presenting what AI tech you are using? You would tell them AI will come from Amazon using a variety of models.
You still choose your model. I’m no more going to say “I’m using Bedrock” without being more specific than I would say “I’m using RDS” without specifying the database.
In various sectors, you need to be able to explain why you/your-system did what it did. Exchange Act Rule 15c3-5 is probably the most relevant in financial circles:

Note: I am neither a lawyer nor in financial circles, but I do have an interest in the effects of market design and regulation as we get into a more deeply automated space.
