<p>Source: I write transformers for a living.<p>There is a piece of knowledge you seem to be missing. Yes, a transformer will output a distribution over all possible tokens at a given step. And none of these are indeed zero, but always at least larger than epsilon.<p>However, we usually don't sample from that distribution at inference time!<p>The common approach (called nucleus sampling or also known as top-p sampling) will look at the largest probabilities that make up 95% of the probability mass. It will set all other probabilities to zero, renormalize, and then sample from the resulting probability distribution. There is another parameter `top-k`, and if k is 50, it means that you zero out any token that is not in the 50 most likely tokens.<p>In effect, it means that for any token that is sampled, there is usually really only a handful of candidates out of the thousands of tokens that can be selected.<p>So during sampling, most trajectories for the agent are literally impossible.</p>

<p>> We, westerner, want our values to prevail.<p>This comes to the core of the issue, and is where I think the disagreement comes from. Many Westerners in fact do not want "Western" values to prevail.<p>Why? For me those values have led to outcomes so horrendously antithetical to _my_ values, that I would not wish them for the rest of the world. Even worse, this Western centrism has led to jingoist conclusions for at least 400 years.</p>

<p>There are many ways to model how the model works in simpler terms. Next-word prediction is useful to characterize how you do inference with the model. Maximizing mutual information, compressing, gradient descent, ... are all useful characterisations of the training process.<p>But as stated above, next token prediction is a misleading frame for the training process. While the sampling is indeed happening 1 token at a time, due to the training process, much more is going on in the latent space where the model has its internal stream of information.</p>

<p>As an expert in the field: this is exactly right.<p>LLMs are trained to do whole book prediction, at training time we throw in whole books at the time. It's only when sampling we do one or a few tokens at the time.</p>

<p>> Second, I think it's human nature to like and want hierarchy.<p>I just want to point out that this is most likely not true, and that this is cultural. The long argument you can find in the book "The Dawn of Everything".<p>In short, when the West came into contact with other civilizations, one of the most striking features of our culture from their point of view was how hierarchical we are.</p>

<p>People need to understand that OpenAI is not a publicly traded company. Sam is allowed to be outrageously optimistic about his best case scenarios, as long as he is correct with OpenAI's investors. But those investors are not "the public", so he can publicly state pretty much anything he wants, as long as it is not contradicting facts.<p>So he cannot say "OpenAI made 20B profit last year." but can say "OpenAI will make 20B revenue next year." Optimism is not a crime.</p>

<p>I'm sorry, but I double checked and I do think you have it wrong. Figure 3 is for "sea level rise _rate_", and that one is indeed high but not significantly so.<p>Quoting "The satellite-based linear trend 1993–2011 is 3.2±
0.5 mm yr−1
, which is 60% faster than the best IPCC estimate
of 2.0 mm yr−1
for the same interval"<p>But, as the authors point out, the worst case forecasts that were within-data, are so for the wrong reasons. Quote "The model(s) defining the upper 95-percentile might
not get the right answer for the right reasons, but possibly by
overestimating past temperature rise."<p>My previous comment is regarding Figure 2, i.e. "Sea Level". I would invite you to read the whole paper. It is only 3 pages and written without jargon.</p>

<p>The paper I cite is for sea level rise. IPCC models from 1990 and 2011 have made forecasts on sea level rise. When we compare those to what actually happened up to 2025, we see that we are slightly worse right now than their highest sea level prediction that was made.<p>We're worse than their worst case scenario, so their models were significantly too optimistic.<p>In the same paper, they also note that for temperature, the models have been accurate.</p>
