This is wrong. https://www.anthropic.com/news/position-open-weights-models
They might say that, but it's a bit of a fig leaf next to the implications of everything else they say. They incessantly complain about open weights models, framing them as dangerous and national security threats. The audience for national security rhetoric isn't HN or industry, it's government.
lol "We support open weight models!"
BUT!!!!!!
"We should not sell powerful chips or chipmaking equipment to China"
"We should crack down on industrial-scale distillation operations."
"All sufficiently capable models, open and closed, should go through mandatory safety testing."
You mean like Google's "Don't be evil" motto? ..
Why would anyone trust these rent seeking corporations? They are losing millions, they know their funds are at risk, Chinese models are catching up to them at lower costs and investors demand returns.
It only makes sense for them to go for regulatory capture. They'll probably advocate for severe handicaps on foreign and domestic models including open source (if not an outright ban).
Once they achieve monopoly, they can do as they please with little competition.
