This obviously an attempt at being able to say a response came from an anthropic model vs say some other model via a model router. As for me, I will keep using my model router, I don't care to be charged more for a name brand. I don't care about the brand at all, it's a commodity.
until your company gets sued for using Dangerous and Shoddy Foreign models and the boss says you can only use the Trustworthy and Premium Aligned labs' models.
