We find that frontier LLMs are surprisingly good at natively reading and writing neural network weights, using a variety of recent tools and algorithms or even via direct weight editing.

For the last decade, fast-to-ship beat fast-to-run. Not anymore.
Since early this year, Michael Malis (of pgrust ) has been showing me interesting things he's done and saying
As I’m writing this, we’re in the middle of an AI-induced mass psychosis. People are literally token-maxxing themselves into hospital beds, scrambling to capture some of that market value before everything is automated away. I can’t blame them. Models keep getting better, programmers are being laid off left and right…
I decided to make my own container runtime for fun, and even though I’m still early on, I’ve learned that Docker is weird . Here’s some weird things I learned about Docker.
Three months ago I would have dismissed claims that AI could replace developers. Today, after using Claude Opus 4.5, I believe AI coding agents can absolutely replace developers.
