Funniest thing is I accidentally got rid of thinking and now my model scores a lot higher on a bench that's heavy on python. I am. LOOK I swear I didn't wake up and choose violence IT IS JUST WHAT HAPPENED MAN

i mean i said people forgot gemini 3 and that google just has a long product cycle... only thing I was wrong about i I expected their model to be much stronger

Anthropic system prompt change that shows how careful you need to be with words: Opus 4.1: "Claude never curses unless the human asks for it" Opus 4.5: "Claude never curses unless the person asks Claude to curse"

entering sft, then reinforcement learning, then small sft then boom, done, I'll have a model, phew

fine tuning specifically to make the LLM a computationalist

okay LLMs pre reinforcement learning are a lot of fun, like I imagine this is what gtp-o4 must have felt like, it's soooooo crazy

Python is objectively easier than Rust for LLMs with similar data size it seems. This could very well be a kinda broken way to actually measure soft metrics like "how hard a language is" to write.

Building a garbage collector (unfortunately need this until I do a v2 of the language) and this paper exists www.cs.princeton.edu/~appel/paper... and damn I've slept so hard on Appel/Shao for no reason

It's over for NixOS the dutch are replacing us with StroopwafelOS

why are you even using a compiler just have the LLM compile the code by hand for you

To be clear, I was at NixCon when I realized.

How do you align a large language model, are there any good benchmarks here? Ideally something gwernian or not just a lobotomizing one, but ones that make sure its aligned with the user etc?

I've seen closures you people wouldn't believe Derivations burning at the edge of /nix/store sync semantics I watched garbage collectors glitter in the dark near the roots of forgotten profiles. All those systems will be lost to time, like store paths being garage collected. Time... to reinstall

nixos so cool cuz the docs just straight up lie. like you can copy and paste a stub and the compiler will say that the option THAT IS IN THE OFFICIAL DOCUMENTATION doesnt exist

PSA: add access tokens to your nix.conf before #NixCon for GitHub. You will get rate limited if you don't. nix.dev/manual/nix/2...
