[Bug] Incorrect model routing: Sonnet being used instead of requested Opus model

Bug Description
You pass off Sonnet as 3.5? That model was supposedly depreciated. Why am I paying $200 a month for a model that is absolutely not worth $200 a month and supposedly isn't in use anymore. Also how is it that you are running down my weekly usage so quickly for Opus 4.1 if Opus is not the model that is even being used? Based on the how the agent was not following instructions and responding, it was obviously not Opus 4.1 or even one of the 4 series models.
