It's just a multiple choice test with question prompts. This is the exact sort of thing an LLM should be very good at. This isn't chat gpt trying to do the job of an actual doctor, it would be quite abysmal at that. And even this multiple choice test had to be stacked in favor of chat gpt.

Because GPT models cannot interpret images, questions including imaging analysis, such as those related to ultrasound, electrocardiography, x-ray, magnetic resonance, computed tomography, and positron emission tomography/computed tomography imaging, were excluded.

Don't get me wrong though, I think there's some interesting ways AI can provide some useful assistive tools in medicine, especially tasks involving integrating large amounts of data. I think the authors use some misleading language though, saying things like AI "are performing at the standard we require from physicians," which would only be true if the job of a physician was filling out multiple choice tests.

I, too, can pass the Boards if you remove all the questions I don't understand.

I’d be fine with LLMs being a supplementary aid for medical professionals, but not with them doing the whole thing.

[–] [email protected] 28 points 5 months ago (4 children)

I wonder why nobody seems capable of making a LLM that knows how to do research and cite real sources.

[–] [email protected] 17 points 5 months ago (1 children)

I mean LLMs pretty much just try to guess what to say in a way that matches their training data, and research is usually trying to test or measure stuff in reality and see the data and try to find conclusions based on that so it doesn't seem feasible for LLMs to do research

They maybe used as part of research but it can't do the whole research as a crucial part of most research would be the actual data and you'd need a LOT more than just LLMs to get that

[–] [email protected] 12 points 5 months ago

Yup! LLMs don't put facts together. They just look for patterns, without any concept of what they are looking at.

[–] [email protected] 8 points 5 months ago (2 children)

Have you ever tried Bing Chat? It does that. LLMs that do websearches and make use of the results are pretty common now.

[–] [email protected] 7 points 5 months ago* (last edited 5 months ago) (2 children)

Bing uses ChatGPT.

Despite using search results, it also hallucinates, like when it told me last week that IKEA had built a model of aircraft during World War 2 (uncited).

I was trying to remember the name of a well known consumer goods company that had made an aircraft and also had an aerospace division. The answer is Ball, the jar and soda can company.

[–] [email protected] 1 points 5 months ago

I had it tell me a certain product had a feature it didn’t and then cite a website that was hosting a copy of the user manual… that didn’t mention said feature. Having it cite sources makes it way easier to double check if it’s spewing bullshit though

[–] [email protected] 0 points 5 months ago

Yes, but it shows how an LLM can combine its own AI with information taken from web searches.

The question I'm responding to was:

I wonder why nobody seems capable of making a LLM that knows how to do research and cite real sources.

And Bing Chat is one example of exactly that. It's not perfect, but I wasn't claiming it was. Only that it was an example of what the commenter was asking about.

As you pointed out, when it makes mistakes you can check them by following the citations it has provided.

[–] [email protected] 7 points 5 months ago* (last edited 5 months ago) (2 children)

Because the inherent design of modern AIs is not deterministic.

Adding a progressively bigger model cannot fix that. We need an entirely new approach to AI to do that.

[–] [email protected] 1 points 5 months ago

Bigger models do start to show more emergent intelligent properties and there are components being added to the LLM to make them more logical and robust. At least this is what OpenAI and others are saying about even bigger datasets.

[–] [email protected] 0 points 5 months ago

For me the biggest indicator that we've barking up the wrong tree is energy consumption.

Consider the energy required to feed a human with that required to train and run the current "leading edge" systems.

From a software development perspective, I think machine learning is a very useful way to model unknown variables, but that's not the same as "intelligence".

[–] [email protected] 3 points 5 months ago

Cohere's command-r models are trained for exactly this type of task. The real struggle is finding a way to feed relevant sources into the model. There are plenty of projects that have attempted it but few can do more than pulling the first few search results.

[–] [email protected] 26 points 5 months ago (2 children)

What would be much more useful is to provide a model with actual patient files and see what kills more people, doctors or models.

Like “Is it Cake”

But life or death is on the line….

“Is it Lupus?” Or “Are you Dying?”

Hypochondriac worst nightmare drama show.

[–] [email protected] 3 points 5 months ago (1 children)

You just described "House M.D."

[–] [email protected] 2 points 5 months ago (1 children)

Well YEAH… it’s never Lupus…

[–] [email protected] 2 points 5 months ago

Except when it was lupus!

After hitting submit I realised that the word "model" was ambiguous, but after considering that for a moment, I realised that I am okay with that.

Nothing like a little ambiguity to keep people smiling..

Supposedly lots of models of G.I. Joe are up for doing rectal exams.

[–] [email protected] 4 points 5 months ago

GPT will require every test and yet for the sake of authenticity randomly perform medical errors.

[–] [email protected] 19 points 5 months ago* (last edited 5 months ago)

All these always do the same thing.

Researchers reduced [the task] to producing a plausible corpus of text, and then published the not-so-shocking results that the thing that is good at generating plausible text did a good job generating plausible text.

From the OP , buried deep in the methodology :

Because GPT models cannot interpret images, questions including imaging analysis, such as those related to ultrasound, electrocardiography, x-ray, magnetic resonance, computed tomography, and positron emission tomography/computed tomography imaging, were excluded.

Yet here's their conclusion :

The advancement from GPT-3.5 to GPT-4 marks a critical milestone in which LLMs achieved physician-level performance. These findings underscore the potential maturity of LLM technology, urging the medical community to explore its widespread applications.

It's literally always the same. They reduce a task such that chatgpt can do it then report that it can do to in the headline, with the caveats buried way later in the text.

[–] [email protected] 10 points 5 months ago (1 children)

Neat but I don't think LLMs are the way to go for these sort of things

[–] [email protected] 4 points 5 months ago (1 children)

I don’t mind so long as all results are vetted by someone qualified. Zero tolerance for unfiltered AI in this kind of context.

[–] [email protected] 3 points 5 months ago (3 children)

If you need someone qualified to examine the case anyway, what's the point of the AI?

[–] [email protected] 6 points 5 months ago (1 children)

The ai can examine hundreds of thousands of data points in ways that a human can not

[–] [email protected] 1 points 5 months ago* (last edited 5 months ago) (2 children)

In the test here, it literally only handled text. Doctors can do that. And if you need a doctor to check its work in every case, it has saved zero hours of work for doctors.

[–] [email protected] 1 points 5 months ago

Residents need their work checked also. I don’t understand your point.

how high processing power computers with AI/LLM’s can assist in a lab and/or hospital environment

This is an enormously broader scope than the situation I actually responded to, which was LLMs making diagnoses and then getting their work checked by a doctor

[–] [email protected] 1 points 5 months ago (1 children)

Why do skilled professionals have less-skilled assistants?

[–] [email protected] 1 points 5 months ago* (last edited 5 months ago)

Usually to do work that needs done but does not need the direct attention of the more skilled person. The assistant can do that work by themselves most of the time. In the example above, the assistant is doing all of the most challenging work and then the doctor is checking all of its work

[–] [email protected] 4 points 5 months ago (2 children)

This research has been done a lot of a times but I don't see the point of it. Exams are something I would expect LLMs, especially the higher end ones, to do well because of their nature. But it says next to nothing about how reliable the LLM as an actual doctor.

[–] [email protected] 2 points 5 months ago* (last edited 5 months ago)

Even those who do well in testing of wrote knowledge can perform poorly in practical exercises. That’s why medical doctors have to train and qualify through several years of supervised residency before being allowed to practice even basic medicine.

GPT-4 can’t do even that.

[–] [email protected] 0 points 5 months ago (1 children)

But it says next to nothing about how reliable the LLM as an actual doctor.

Yet these tests say anything about how a human would be as an actual doctor?

[–] [email protected] 1 points 5 months ago (6 children)

It says as much as it does for an LLM but doctors have to have a lot of field experience after passing these tests before they get certified as doctors.

The 17th percentile in peds is not surprising. The model mixing it's training data with adults would absolutely kill someone.
