The AI Scientist: Towards Fully Automated AI Research, Now Published in Nature Nature: nature.com/articles/s4158… Blog: sakana.ai/ai-scientist-n… When we first introduced The AI Scientist, we shared an ambitious vision of an agent powered by foundation models capable of executing the entire machine learning research lifecycle. From inventing ideas and writing code to executing experiments and drafting the manuscript, the system demonstrated that end-to-end automation of the scientific process is possible. Soon after, we shared a historic update: the improved AI Scientist-v2 produced the first fully AI-generated paper to pass a rigorous human peer-review process. Today, we are happy to announce that “The AI Scientist: Towards Fully Automated AI Research,” our paper describing all of this work, along with fresh new insights, has been published in @Nature! This Nature publication consolidates these milestones and details the underlying foundation model orchestration. It also introduces our Automated Reviewer, which matches human review judgments and actually exceeds standard inter-human agreement. Crucially, by using this reviewer to grade papers generated by different foundation models, we discovered a clear scaling law of science. As the underlying foundation models improve, the quality of the generated scientific papers increases correspondingly. This implies that as compute costs decrease and model capabilities continue to exponentially increase, future versions of The AI Scientist will be substantially more capable. Building upon our previous open-source releases (github.com/SakanaAI/AI-Sc…), this open-access Nature publication comprehensively details our system's architecture, outlines several new scaling results, and discusses the promise and challenges of AI-generated science. This substantial milestone is the result of a close and fruitful collaboration between researchers at Sakana AI, the University of British Columbia (UBC) and the Vector Institute, and the University of Oxford. Congrats to the team! @_chris_lu_ @cong_ml @RobertTLange @_yutaroyamada @shengranhu @j_foerst @hardmaru @jeffclune

GPT-5.2 derived a new result in theoretical physics. We’re releasing the result in a preprint with researchers from @the_IAS, @VanderbiltU, @Cambridge_Uni, and @Harvard. It shows that a gluon interaction many physicists expected would not occur can arise under specific conditions. openai.com/index/new-resu…

@mathelirium My point is that Statistical Physicist thinks in terms of Statistics and Probability, not only mathematicians or statisticians.

@mathelirium Einstein, already in 1905, was thinking as a Statistical Physicist, coming from the 19th century Statistical Mechanics of Boltzmann and others.

Like Markov and Kolmogorov, Einstein had the same gift for finding structure inside noise, even though he was a Physicist.🫡 Einstein’s 1905 paper on Brownian motion doesn’t get the same spotlight as General Relativity, but it’s still an astonishing piece of work. It takes a messy, noisy phenomenon and extracts three hard facts from it: First, the randomness is physical. The motion is molecular impacts made visible. Second, one path looks like chaos, but the cloud has a rigid scaling law...mean-square displacement grows like t, so the width grows like √t. Third, the cloud evolves deterministically. Its density ρ(x,t) solves the heat equation PDE ∂ₜρ = D∂ₓₓρ. So Brownian probability spreads the same way heat spreads! #BrownianMotion #Einstein1905 #HeatEquation #StochasticProcesses

@LuisRosendo_ @Claudiashein @AmiaMexico @m_ebrard @SE_mx Excelente. ¡Enhorabuena!

Motiva y compromete acompañar a la Presidenta @Claudiashein a la reunion con la Industria Automotriz @AmiaMexico para apoyar a esta importante industria generadora de casi 800 mil empleos para nuestro país. @m_ebrard @SE_mx #TMEC

@wtgowers Very interesting.

I crossed an interesting threshold yesterday, which I think many other mathematicians have been crossing recently as well. In the middle of trying to prove a result, I identified a statement that looked true and that would, if true, be useful to me. 1/3

@grok @salmanPak76 @PhysInHistory @grok give me the content of this book by chapters

This is the second edition of "An Introduction to Geometrical Physics" by Ruben Aldrovandi and José Geraldo Pereira, published by World Scientific. It provides an introductory overview of topology and differential geometry, emphasizing their unifying role in various physics concepts and applications.

Hi! Suggest me a topic for a THREAD! Going to post about it tonight.
