I'm wondering: what will happen with the API? While they can give "normal" users the middle finger with shrinkflating model capabilities and opacity; I don't think businesses will be too happy sending prompts to the "super-intelligent" model that suddently is performing way worse despite the client not changing their prompts.

Or they'll keep that "weird" (not so hard to understand IMO) naming scheme for the API, which means any actual "power user" might choose instead to pay API credits and run their own Open WebUI (or any other ChatGPT-Like UI).
