Mike Conover: prediction

…But the kind of thing that, like a small multi-billion dollar mom and pop shop might be able to pull off. The benefit that you get from that is like, I think, diminishing over time. And so I think fewer companies are going to make that capital outlay. And I think that there's probably some material negatives to that. But the other piece is that we're seeing that, at least in the past two and a half, three months, there's a convergence towards like, well, these models all behave fairly similarly. And it's probably that the training data on which they are pre-trained is substantially overlapping. And so it's generalizing a model that generalizes to that training data. And so it's unclear to me that you have this sort of balkanization where there are many different models, each of which is good in its own unique way, versus something like Lama becomes like, listen, this is a fine standard to build off of. We'll see, it's just like the upfront cost is so high. And I think for the people that have the money, the benefit of doing the pre-train is now less. Where I think it gets really interesting is how do you differentiate these and all of these different behavioral regimes? And I think the cost of producing instruction tuning and fine tuning data that creates specific kinds of behaviors, I think that's probably where the next generation of really interesting work starts to happen. If you see that the same model architecture trained on much more training data can exhibit substantially improved performance, it's the value of modeling innovations. For fundamental machine learning and AI research, there is still so much to be done. But I think that much lower hanging fruit, I guess, is developing new kinds of training data corpuses that elicit new behaviors from these models in a specific way. And so that's where, when I think about the availability to like a year ago, you had to have access to fairly high performance GPUs that were hard to get in order to get the experience of multiple reps fine tuning these models. And what you're doing when you take a corpus and then fine tune the model and then see across many inference passes, what is the qualitative character of the output, you're developing your own internal mental model of how does the composition of the training corpus shape the behavior of the model in a qualitative way. A year ago, it was very expensive to get that experience. And now you can just recompose multiple different training corpuses and see like, well, what do I do if I insert this set of demonstrations or I ablate that set of demonstrations? And that I think is a very, very valuable skill and one of the ways that you can have models and products that other people don't have access to. And so I think as more people, as those sensibilities proliferate because more people have that experience, you're gonna see teams that release data corpuses that just imbue the models with new behaviors that are especially interesting and useful. lities proliferate because more people have that experience, you're gonna see teams that release data corpuses that just imbue the models with new behaviors that are especially interesting and useful. And I think that may be where some of the next sets of kind of innovation differentiation come from. Yeah, yeah, when people ask me, I always tell them the half-life of a model, it's much shorter than a half-life of a dataset.…
