OpenAI is really cooking lately. The difference in writing quality of 5.4 and the competitors is massive

@ylecun congrats

@ziv_ravid @JudahGoldfeder @ylecun Ravid, did human intelligence arise from the constraints of earth or are humans on earth-like planet because we are the ideal intelligence and earth-like planets are the only ones able to support it?

Why should we expect machine intelligence to be useful on earth?

test time compute indeed

My baby spends much more effort on producing output than he does taking input

Lessons in that

ratio of cost of A100/hour to cost of 1 pack of premium baby wipes 📉

it's so over

@deanwball "These guys are just that good"

[Ari Karchmer @non0knowledge]

Has anyone tried asking the babies how they implemented their RL? @ylecun

[Ari Karchmer @non0knowledge]

I'm suspicious of resnets. can't say why

[Ari Karchmer @non0knowledge]

@roydanroy @hayou_soufiane I'm not sure this is necessarily a circular definition, though it may be refined. It reminds me of cryptography style definitions which model "knowledge" inside a "machine" as that which is extractable in polynomial time. See for example "proofs of knowledge"

@gavinrbrown1 Hi Gavin! Hope you're doing well. Actually, I just emailed this same man, and he also told me that he now spends more time responding to email from alumni than reviewing dissertations. Message received :)

@Turn_Trout This looks really cool. Is there any obvious relation to Component Modeling (https://t.co/nu0XVpk6Sp)?

@PhilFoden i just finished my phd in computer science at boston university, shoutout to you (and pep) for the inspiration

@Dan_Jeffries1 @HermanNarula Isn't their argument centered around the fact that when it comes to x-risk, evidence is no longer a prerequisite to funding and taking preventative measures? In other words, non-zero chance of extinction has infinitely negative expected payoff, so little evidence is needed.

Accepted to #ICML2024: “On Stronger Computational Separations Between #Multimodal and Unimodal #MachineLearning” (https://t.co/ci0EDO3F3x)

[Ari Karchmer @non0knowledge]

What other computational separations exist? Can they be more “natural” if the computational advantage is smaller (we study super-polynomial advantages)? How else can we use formal relationships between Crypto and ML to heuristically argue about “real-world” ML phenomena?
