I wrote a little piece about a pet peeve of mine. People claiming that LLMs "lie". Writing is great to get your thoughts in order and it feels as if there's a bit more at stake when writing for a potential audience.

Might do more of these in the future.

Language Models Don't Lie
Discussions and coverage of AI systems such as chatbots based on LLMs uses increasingly anthropomorphic language, such as claiming that LLMs lie. But LLMs cannot lie, and here's why.

Chatbots — LLMs — do not know facts and are not designed to be able to accurately answer factual questions. They are designed to find and mimic patterns of words, probabilistically. When they’re “right” it’s because correct things are often written down, so those patterns are frequent. That’s all.

If you don't think I provided enough interesting findings in my last post, @annarogers.bsky.social has you covered in her latest post on our paper! ✨

🤯 We use the term 'intelligence' a lot, but wth do we mean?

We got 303 survey responses from researchers. The most agreed-on criteria are generalization, adaptability & reasoning.

You can find the answers to more interesting questions regarding the beliefs of researchers on LLMs and "Intelligence" in the full paper!

This work was done in collaboration with @terne.bsky.social, @heinrichst.bsky.social, and @annarogers.bsky.social

❓Do researchers believe current LLM based systems are intelligent?

✔️Generally not - although junior researchers are more willing to attribute intelligence to current systems!
Do researchers agree that current AI systems based on LLMs are "intelligent"?
brtrm.bsky.social
❓What do AI researchers believe to be key criteria for intelligence?

✔️Researchers across fields agree that Generalization, Adaptability, & Reasoning are key components of intelligence!

If you’re at ICLR, swing by poster #246 on Saturday from 10-12.30 to hear more about our work on modulating the reasoning performance of LLMs!

ICLR is coming up and I thought I'd use the chance to advertise our paper: "Improving 'Reasoning' Performance in Large Language Models via Representation Engineering" ✨

Also happens to be my first publication as a PhD Student at @itu.dk

The problem with most machine-based random number generators is that they’re not TRULY random, so if you need genuine randomness it is sometimes necessary to link your code to an external random process like a physical noise source or the current rate of US tariffs on a given country.

Looking forward to presenting our poster alongside Oliver at the conference in Singapore! Hope to see you there! ✨

We of course took the chance to discuss:
🔹the implications of our results for LLM reasoning
🔹the use of the term "reasoning" to discuss LLM computations
🔹 whether LLMs can be said to do reasoning at all 🤔
brtrm.bsky.social
We:

1️⃣ Derive steering vectors from LLM representations on "reasoning" tasks.
2️⃣ Apply them as a linear transformation to the representational space to improve "reasoning" performance.

A very simple tweak resulting in a slight improvement! 📈

its amazing how chatgpt knows everything about subjects I know nothing about, but is wrong like 40% of the time in things im an expert on. not going to think about this any further

That this is a misrepresentation is something we also show in our forthcoming survey paper on Intelligence and LLMs in researcher communities (preprint coming).
brtrm.bsky.social
It’s a bit disturbing to hear Ezra Klein, someone I admire a lot, stating that “… virtually everyone working in this area (AI) are saying that [AGI] is coming”. In my view this is a gross misrepresentation of the actual sentiment in the field.
brtrm.bsky.social
Sorry, my bad for being a bit quick there! When you say "popular AI denial" I think more of people just not wanting to accept that these systems are *actually* intelligent. I think it's a shame to discuss healthy skepticism in a derogatory manner ..
brtrm.bsky.social
I disagree, and what exactly do you mean by AI denial? One can state that there are legitimate (limited) use-cases of modern AI while not subscribing to the belief that current models show "sparks of AGI".
brtrm.bsky.social
Very harsh writing by Edward Zitron - but he voices concerns I have myself.

Developing helpful 'AI' systems could provide value, but the way current commercial 'AI' systems are being hyped is not very helpful and quite likely detrimental.

Not to mention that rather than being well-established observations, (1) is difficult if not impossible to assess without a proper definition of intelligence and (3) seems to be complete blather.
