Description

Tencent dropped a 770B-parameter open-weight model with a 1M-token context, while California carved open-source operating systems out of its age-verification law — two very different reminders that the open ecosystem's position is being set right now. Underneath, a run of research quietly attacked the field's assumptions: about memory hierarchies, about placement objectives, and about whether our benchmarks measure anything.
