On Nano "it's not even close when you test it in real scenarios" - what have you seen? What kind of things can GPT-5 Mini handle that GPT-5.4 Nano cannot?

We’re using GPT-5-mini in an enterprise data-processing workflow, and we too see that GPT-5.4 nano performs materially worse for our requirements, roughly 30% worse as measured through our test suite.

Also can confirm gpt-5.4-nano was unable to even keep up with 4.1-mini. Had to move off of OpenAI once 4.1-mini was retired
