become an animist and never again worry about whether the machines are thinking. so are the trees? the machines can help us make better websites though

i'm sure we could get it to come up with conjectures that *would* be interesting. but interesting is at least in part a social property!

the space of intelligences is large, and so there exist smart minds that won’t seek power and equally smart minds that will seek power

keep your data to yourself, cus you deserve to! 💪 we made the first multi-gpu post-training stack that is private -- it actually keeps your data untouchable by anyone but you in all stages of the process. 🗝️ take a look at how we did it, in collab w/ tinfoil.sh: www.workshoplabs.ai/blog/private...

The increasingly-hyperbolic METR graph is actually good news for safety. We just have to survive a brief singularity in March, and then afterwards the models will never be able to do more than undo a few hours' worth of work

The big problem is that science often doesn't have the advice people WANT. Like, weight loss isn't much more complicated than calories in/calories out. Sometimes you get lucky/unlucky but vaccines still work at the population level. etc. individual papers aren't meant to draw conclusions from, etc.

Want to finetune the largest open source frontier language models? Turns out you can't! So much for "open" source... But fear not, we (workshoplabs.ai) figured out how to finetune Kimi K2, so you don't have to. Peep our blog below to see how we did it :) www.workshoplabs.ai/blog/open-we...

really interesting to see their framing of "big tech" (with its connotations) next to "big ai" (which ive not seen as a term before)

The AI discourse sometimes seems to center on "Is AI good or is it bad?" I find this framing unproductive. AI is not a fixed thing. I would prefer to ask "How might we use this technology for good, and mitigate the bad?" What a shame if the best use we can come up with is no use at all.

claiming that u “priced it in” is just post hoc rationalization unless u have cold hard proof of the causal trace that u made predictions off of from before it happened

Some useful rules of experimentation: (1) change one thing at a time, never more (2) run the edge cases to confirm they work the way you expect Gets you surprisingly far

pretty cool work by natalie and co. i think that its great to treat models as things to actively/dynamically/iteratively test, as its ~impossible to touch the surface area of model deployments with internal testing! sharing some thoughts below

Who is AI For?
Who is AI for right now? There are obvious use cases. Image generation for people who want filler art for work presentations, or just to mess around. Coding assistance for people who code, vibe coding...
