I wanna believe everything you say (because you generally are a credible person) but a few things don't add up: 1. Weakest ever LLM? This one is really making me scratch my head. For a period of time Llama was considered to THE best. Furthermore, it's the third most used on OpenRouter (in the past month): https://openrouter.ai/rankings?view=month 2. Ignoring DeepSeek for a moment, Llama 2 and 3 require a special lice…

LLMs literally are just predicting tokens with a probabilistic model. They’re incredibly complicated and sophisticated models, but they still are just incredibly complicated and sophisticated models for predicting tokens. It’s maybe unexpected that such a thing can do summarization, but it demonstrably can.

I'm going to wear the tinfoil hat: a firm is able to produce a sought-after behavior a few months later and throws people off. Is it more likely that the firm (worth billions at this point) is engineering these solutions into the model, or is it because of emergent neural network architectural magic? I'm not saying that they are being bad actors, just saying this is more probable in my mind than an LLM breakthrough.
It depends what you mean by "engineering these solutions into the model". Using better data leads to better models given the same architecture and training. Nothing wrong with it, it's hard work, it might be with as specific goal in mind. LLM "breakthroughs" aren't really a thing at this point. It's just one little thing after another.

Text generation and search are the drivers for some trillions of dollars worth of economic activity around the world.
> trillions of dollars That is monetary value. The poster may have meant "delivery" value - which has been limited (and tainted with hype). > Text generation Which «text generation», apart from code generation (quite successful in some models), would amount to «trillions of dollars worth of economic activity» at the current stage? I cannot see it at the moment.
A good search engine could probably take over llm.

I'm ignorantly curious of what type of math will work in your view. Genuine question, I just want to be educated.
There is no type of math that can model conceptual reasoning. You can use conceptual reasoning, however, to do math.
But I'm even less sure what conceptual reasoning is.

The error with that is that human reasoning is not mathematical. Math is just one of the many tools of reason.
Intransitive preferences is well known to experimental economists, but a hard pill to swallow for many, as it destroys a lot of algorithms (which depends on that) and require more robust tools like https://en.wikipedia.org/wiki/Paraconsistent_logic > just one of the many tools of reason.

(It's very common, esp. with educationally traumatized Americans, e.g., to identify Math with "calculation"/"approved tools" and not "the concepts")
"No amount of calculation will model conceptual thinking" Sorry to come across as patronizing

Thanks for the links, the "tradeoff" aspect of paraconsistent logic is interesting. I think one way to achieve consensus with your debate partner might be to consider that the language rep is "just" a nondeterministic decompression of "the facts".

It’s not true The idea that meaning is not impacted by language yet is somehow exclusively captured by language is just absolutely absurd Like saying X+Y=Z but changing X or Y won’t affect Z
Language is a symbolic system. From an absolute or spiritual standpoint, meaning transcends pure linguistic probabilities. Language itself emerges as a limited medium for the expression of consciousness and abstract thought. Indeed, to say meaning arises purely from language (as probability alone) or, to deny language influences meaning entirely are both overly simplistic extremes.
Like I said in another comment, I can think of a dozen statistical and computational methods where if you give me a text and its synthesis I can find a strong probabilistic link between the two.

> LLMs learn from examples where the logits are not probabilities, but how a given sentence continues (only one token is set to 1). But enough data implies probabilities. Consider 2 sentences: "For breakfast I had oats" "For breakfast I had eggs" Training on this data, how do you complete "For breakfast I had..."? There is no best deterministic answer. The best answer is a 50/50 probability distribution over "oats" a…
So it is still largely, probabilities pattern matching?
