By the numbers

Thinking Machines reached number one American open-source model ranking in 6 months, but sits at number 10 globally with 9 Chinese models ranked above it.

“At least the most generous take towards thinking machines is that they've only been working on this model for 6 months and within that time they'd become the number one American open-source model. But then the less generous take would be the companies existed for a year and a half and then they've come up with yes, the number one American open source, but there's nine Chinese models on top of them because they're number 10 open source overall.”
