Recent content samples (what the inference above was drawn from)

The thing about Chinese model distillation that is less known today is that it is not a targeted top down state directed effort, but an obvious scaling choice for researchers at any N-1 lab, and that the data and traces…

The first RL env major acquisition outcome?? Mechanize for 1.5B! Makes a lot of sense when it’s been in the data discourse for a long time now that GDM’s synth capabilities weren’t up to OAI and Ants. Many of the recent…

Far too many aspiring data sycophants, armed with their shovels, do not understand the compute and RL scaling algo dynamics that lead us down this path in the first place, and thus cannot distinguish
