there's lots of new folks around here lately, so a quick (re)intro 👋

im Kory, Research Scientist at @GoogleDeepMind working on generative AI models and agents

i've spent ~10yr doing live theatre comedy alongside machines (my hair is ... shorter now)

always trying to get great technology into the hands of creative people

if this resonates, say hey and tell me about what you are building...

We asked GPT-6 Astra to edit Qwen3.5-0.8B weights to improve math.
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: frontier LLMs can now natively read/write neural network weights! 🧵
