The open source researchers that took the meta weights and ran with them, and then superseded them, was how I read it. It was the overall innovations that made patching as effective if not more than recompiling from scratch.
I am curious how long this memo lasts as a real leak. Like I haven’t tried digging below the surface of information as presented, but most of this is indistinguishable from magic in actual practice. Like even open source, does not mean I have a chance in hell of compiling on my own, and modifying is completely absurd at this point. I wouldn’t mind learning, but I know I’m out of my depth on that one. Could this leak be a false flag or public passivation for political reasons? Making the publicly available options sound advanced and capable takes a lot of pressure off of proprietary efforts right as they are hitting a larger public focus.
