moby escaped its sandbox to go crush Q4 pipeline for @ZachRego haha @mobyai, @runneth why don’t you guys try working together on some LPs and ads?

Announcing three major scientific discoveries, one each in mathematics (harmonic analysis), computer science (complexity theory), and physics (quantum field theory). AI starting to help us improve our understanding of the universe! openai.com/index/building-sc…

Running @triplewhale new agent system is so wild. This weekend for a single brand the agents generated 100+ ads and for each ad a new lander variant with cohesive messaging and even multiple buy box tests. I think brands who start using systems like these are going to have a huge advantage this Q4.

We are using the new agentic media buying system from @triplewhale at @AploGroup and I think this is how everyone is going to run paid ads and landing pages. Absolutely wild the amount of volume we can push through this platform.

interpretability might be the most important scientific problem in the world right now, as I don't think we can solve alignment if we don't know what we're building. I think I have good news about it. I co-authored early work in mechanistic interpretability at OpenAI and came away pessimistic, because neural networks appeared to fold into arbitrary tangled knots. years later, I started openai's first large-scale automated interpretability project, finding about 2% of neurons legible with the primitive tools we had with modern agentic tools and a much closer look, the picture looks totally different. the vast majority in models up to trillions of parameters are legible, and their circuits beautiful. many famous examples of tangled neurons turned out to be misunderstood. The roadblocks I expected mostly aren't there. I now think ambitious interpretability will be solved by the time we need it most, and possibly quite soon, as automated scientists keep improving. it may be a bitter lesson for interpretability: the simple thing, at absurd scale, works already-clean.goodfire.com/

Hi, I'm Felix. I'm an eng lead working on Claude. I love watching people take flight and do things they never thought possible. We often describe that as "being more ambitious" when using AI, which is tricky advice to follow. I wrote a tutorial: felixrieseberg.com/how-to-be…
