Auto Mode Clarity

Given the current pricing model is pushing a lot of us to auto mode, it would be a good idea to see which model responded to a request in this mode: I understand (though this isn’t clearly communicated) that the models are taken from a “premium” pool, but it would be very helpful to know if a response and edit were done by Claude 4 Sonnet, Gemini 2.5 pro, Gpt-4.1 etc.; some users users have likely developed preferences and the ability to decide which models to trust for specific tasks.
Thanks!
