This was a really fun conversation with @billgates.bsky.social and Peter Lee, and I hope you enjoy it too!

(roughly we talk about our respective first contacts with genAI/LLM/sparks and what we see as missing steps/future steps for it to truly transform healthcare)

o3-mini is a remarkable model. Somehow it has *grokked arxiv* in a way that no other model on the planet has, turning it into a valuable research partner!

Below is a deceitfully simple question that confuses *all* other models but where o3-mini gives an extremely useful answer!

Nice to see SLMs making it to the 10 Breakthrough Technologies of last year!!!

What will really matter in the long run? That’s the question we tackle each year as we compile this annual list.

Tomorrow morning at the Simons Institute : Sparks versus embers, can LLMs solve major open mathematical conjectures?

(FWIW I agree with everything in the Embers paper, so I guess the debate will be about the conclusions to draw from current evidence!)

It's looking like all the open problems I have thought about in the last 10 years are now solved (or in some cases on the verge of being solved)? Latest case in point this beautiful new paper: arxiv.org/abs/2411.18614 . I'm glad we (humans) got all this results just in time!
Optimal root recovery for uniform attachment trees and $d$-regular growing trees
We consider root-finding algorithms for random rooted trees grown by uniform attachment. Given an unlabeled copy of the tree and a target accuracy $\varepsilon > 0$, such an algorithm outputs a set of...

Was there a paper hinting at that 18 months ago? Hmmm 🤔🤣🤣
It is funny how much of the dominant discussion about LLMs eighteen months ago (can AI pass the Turing test? can it do tasks that are not explicitly in the training data? is it a stochastic parrot?) faded. Lots of questions left (if/when it can reason, etc) but a big quiet shift in assumptions.

Blast from the past, wrote these equations in this form 6 years ago, I remember it felt quite clarifying at the time ... A bygone era unfortunately

Had a fantastic time at OpenAI’s dev day in Singapore! So much energy here, and the depth of knowledge policy makers have about AI is incredible. Bumped into some old Singaporean classmates of mine too

Today is the 6 months anniversary of phi-3, I wonder what these guys have been cooking up since then 🤔
