Name any 2 or 3 that published bleeding edge research and similar in the last 6 months.

Well I can't think of even one at the moment, to be honest might be biased but all Chinese research labs are largely oss except Alibaba now.

I am certain there are lots of American labs that claim to do it, but either they are marketting in hype since they aren't even close to the frontier or contrarily just don't make anything of significant value public/oss.
