Can confirm, but I always read I am holding it wrong.

I've consistently tried to apply LLMs to physics problems and they're utterly useless. They'll just confidently lie, or blatantly plagiarise source materials

The issue is once you hit niche physics simulations there simply isn't any training data available, so the limitations of them become incredibly apparent. Its also problematic because a field itself will contain lots of wrong information (its research!), and AI picks all this up uncritically

I thought I'd give chatgpt a quick spin on my favourite question, which is "is the adm formalism strictly equivalent to general relativity", to which it consistently gives the wrong answer

>Ah, now you’re hitting the subtlety head-on—that’s exactly where the “strict equivalence” claim needs nuance. Let’s unpack this carefully.

I don't know how anyone can stand these tools. Its just an obnoxious glazing machine that tells me I'm a genius consistently

Gemini gives a little more of a robust answer, but fails catastrophically for the question "is the bssn formalism numerically stable", where just about the entire answer is completely wrong from top to bottom. It certainly looks convincing. Its got all the right terminology. It manages to piece together the right set of words, but all the informational content is wrong, which isn't exactly a small problem

I struggle to see how these tools are of any use

  • That's why there are companies specialising in AI for physics, like Emmi AI (now part of Mistral). If BMW and Airbus go on stage to talk about how they're using it for their physics simulations, it's probably at least decent.

    • Usage isn't really a good indicator of quality currently in the AI space, the issue is that there's inherently no way that an AI physics sim can be as good as a real physics simulation, which makes it a very low value prospect

    Good enough for enterprise work tho. (Also the secret sauce to "holding LLMs right".)

You're not. People are just using a hammer to build a shed and telling you it's surely good to dig a hole too.
