Ok, I was slightly skeptical at first, but then took a bit deeper look and now feel it's completely misleading. The authors simply asked Astra to not do any *gradient descent* training, so guess what? Astra just did gradient-free training instead, wtf.. github.com/RikiyaT/lm_und…

It directly changed only 0.016% of weights, fixing 0.8B's reasoning loops & improving math up to 6x and even instruction following 3x, without gradients or training.
We call this Weight-Space Programming:
