Worth reposting a follow-up tweet from the author Tom Zahavy [1] after this made the rounds on X/Twitter recently:

> A few reflections on my "LLMs Can’t Jump" paper:

> My position paper recently got some traction here, so I wanted to share a few thoughts and clarify a few things.

> First things first: some people are framing this as "DeepMind is throwing cold water on AI for science" or claiming the paper argues LLMs can never make real scientific discoveries. This is NOT the case.

> This is a personal position paper, not the company's view on AI for science. This is also not my position. As a core contributor to AlphaProof (the first AI system to win an IMO medal), I know firsthand that my colleagues at DeepMind, other frontier labs, and academia have made amazing discoveries with LLMs and will continue to do so. This paper is NOT an "LLMs are a dead end" kind of thing.

> Rather, the paper is the result of a deep dive I took to study the invention of General Relativity. I wanted to explore what it would take for a modern AI system to make that exact kind of jump. Specifically, I focused on the equivalence principle—a key axiom that Einstein formulated through thought experiments grounded in his physical intuition. I was trying to figure out what it would take to give modern AI systems that sort of thinking.

> Giving AI this specific capability isn't necessarily the most urgent thing to do next. It is very likely that improving our current recipes will lead to many exciting discoveries in the near future. In fact, that is what I am personally working on these days (sorry to disappoint you!). It is also quite possible that I am wrong, and that simply scaling our current systems will lead to new inventions in physics and elsewhere.

> Nevertheless, this was my position last winter when I wrote the paper, and I'm sticking to it. I think that there are a few interesting ideas to explore in this space which could influence the next generation of AI systems. I was very lucky to receive a lot of interesting feedback about this position—thank you for all the messages!

It's weird because the equivalence principle is very unintuitive. Aristotle's Mechanics does not have it. It took almost two thousand years to discover inertia that is the most simple version of the equivalence principle. Einstein understood the idea of the the equivalence principle because he had a physics degree, not because he feel that in real life.

Moreover, if you ever have to study or teach Quantum Mechanics, physical intuition gets in the way. A lot of properties contradict the physical intuition but after a while you get use to them. If we continue with Einstein, the photoelectric effect does not aperar in real life.

I mean Einstein had help, he was networked with the best scientific minds of the planet and his discoveries were grounded in experimental results that contradicted existing theories (at least for specialized relativity), and without Riemann’s work he wouldn’t have been able to formulate his theory either. So not sure if AI couldn’t do that if you kept feeding it with new research results and let it correspond with top human scientists. Einstein was a genius but I don’t think his thought process is beyond what an LLM could simulate. And again this is probably the most impressive scientific achievement in theoretical physics in the 20. century so maybe it’s hanging the bar a bit high for LLMs.

Moreover anyone glomming onto this paper for goal-post-shifting “AI can never” should:

1. Read the last sentence of the abstract, and

2. Reflect that frontier reasoning agents already increasingly integrate multimodal models.
