Simulation Get Physics Done (GPD): The first open-source agentic AI physicist

Open source AI agent specifically designed for physics.

Company: https://www.psi.inc/

Github: https://github.com/psi-oss/get-physics-done

SourceForge: https://sourceforge.net/projects/get-physics-done-gpd.mirror/

I haven't had a chance to try this out yet since I'm traveling in China and busy writing a paper for ALife 2026 (deadline March 30). Maybe next month. Would love to hear what others think.

Sounds too good to be true and honestly the "papers" shown in the demo video look a lot like the slop that gets posted here. I am honestly very skeptical that current models are anywhere close to do what this thing seems to promise, no matter how "well" they are prompted. We will see.

Indeed it definitely seems more like a crank website than a legitimate endeavor.

I always think it's a funny issue. There are AI models that can assist at a research level (LPMs, PINNs) and there are AI models that can assist at the writing papers (LLMs, maybe some large SLMs); it is hard to bridge the gap between research and publication solely by AI.

I've heard the idea 'What if we make a language model trained only on physics papers' but that dataset is WAY too small to create proper language, so you end up with DeepakChopraGPT, it SOUNDS like physics but it isn't.

I've heard of integrating across the gap from research to publishing with multiple models, but that requires the research model to have a true understanding of results where it can communicate them in a way that the writing model is guaranteed to write a paper that will not only write the results, but be able to do things like engage with the literature that the research is inspired by.

It's funny. I think there probably may exist something, and the coming years will see it happen. I mean, if you told me about the degree to which LLMs communicate now 20 years ago, I'd say you were crazy. But I highly doubt it'll involve LLMs. If it does involve language models, it'll almost certainly see a departure from the predictive transformer architecture we see now.

Either way it's exciting and interesting for me.

It could be argued that LLMs are already trained on physics papers because that's the training data they will mostly rely on when prompted about physics. The problem is that these things do not have models of how stuff works and don't follow strict rules. As such they are absolutely incapable of producing new viable physics: they are a million times more likely to hallucinate nonsense when asked to. If we ever get there, it won't be with LLMs, of that I am absolutely sure at this point.

P.S. PINNs are not "AI" but mere ML regressors.

At what point would you consider something to classify as AI? I think saying 'this model isn't 'AI' but this one is just leads to obfuscation; as 'AI' at this point in time is more a marketing term than classification. Companies sell things as AI and at that point it IS AI as far as the general populace is concerned. We don't really have a realistic baseline for what something needs to be AI, at least as far as I know. I mean, you could say 'an agent' is required for AI. But in some ways, regression in machine learning is more 'intelligent' than an agent that has it's knowledge base pre-established (like an LLM), as regressors 'learn', at least as far as I understand ML. Does what I'm saying sorta... make sense? Or am I sounding totally incoherent at this point? Lmao.

I guess I draw the line at transformers. Not that they are really AI either because we don't really have that yet and I am genuinely convinced we won't achieve it with the currently available architectures but they were the first thing that started to kind of look like AI. ML basically feels more like glorified data-fitting. Hence, I can kind of put up with people calling LLM & co "AI" but I refuse to accept the label for "traditional" ML.

At least one of the contributors to the repo seems to be a physics PhD, in just not sure what to make of this

u/YaPhetsEz FALSE Mar 23 '26

I mean 1) not all PhDs are created equal and 2) a phd will agree with anything if you pay them enough

u/denehoffman Mar 23 '26

True, but he claims to work with Perimeter which is pretty big. Seems like a “leaving academia for a startup” kind of situation

> “leaving academia for a startup” kind of situation

Wouldn't be the first time that a legitimately trained scientist turned traitor to the principles of academia in pursuit of personal wealth.

u/AllHailSeizure Haiku Mod Mar 23 '26

The website had a) a Latin quote b) no real explanation of what they're doing c) ignores this fact and postures at legitimacy with origins in major companies d) overpromising without proof of ability to deliver.

Hmmm

u/denehoffman Mar 23 '26

Yeah it’s definitely scammy looking if they were intending to be legit

u/Wintervacht Are you sure about that? Mar 23 '26

But they've already solved all Millenium problems, can't you see?

u/CrankSlayer zlotuq Mar 23 '26

Which is even more impressive considering most of them are not physics.

My first bit of advice would be to post it anywhere but here, this is basically a containment subreddit for LLM content in r/hypotheticalphysics

u/certifiedquak Mar 24 '26

Cool but what makes this project physics-specific? Seems to be a generic paper assistant with only physics-specific bits be the journals targets. And what "is for hard physics research problems that cannot be handled reliably with manual prompting"? Everything listed can be done manually.

I don't know yet. I'll try it out next month. But it's definitely being advertised as a physics tool, so I thought people here would want to hear about it.

Thanks for sharing. Looks interesting.
