Who is this vendor that is consistently providing high quality inference for all families of open weight models at a competitive cost? That's a serious questions that I really interested in the answer too. I have 25 providers included into my coding agent harness not because I care about vendor neutrality, but because I have to keep adding new ones as inference quality degrades at the providers I was using. Its quite tiresome.
