Jev: Fable-level model that doesn’t charge for output tokens because they’re too cheap to meter

OpenAI’s o1 model correctly diagnosed 78.3% of cases in NEJM clinicopathologic conferences, outperforming human physicians. The model also maintained high accuracy on real-world, unstructured data from a major emergency department. #MedSky
Performance of a large language model on the reasoning tasks of a physician
More than 65 years ago, complex clinical diagnostic reasoning cases were introduced as the gold standard for the evaluation of expert medical computing systems, a standard that has held ever since.…

I came to Minneapolis to report on what's going on, and one of the main questions I showed up with is "just what is the scale of the resistance?" After all, we're all used to the news calling Portland a "war zone" or whatever when it's just some protests in one part of town.

We introduce epiplexity, a new measure of information that provides a foundation for how to select, generate, or transform data for learning systems. We have been working on this for almost 2 years, and I cannot contain my excitement! arxiv.org/abs/2601.03220 1/7

Yep. This has been my approach so far
I love all of this take.
Also "frustration tolerance" is a wonderful turn of phrase, and it sounds less intimidating than the one we often use in Education, "productive struggle".

TITANS & MIRAS: real continual learning
MIRAS = a unifying theory of transformers (attention) and state space models (SSM, e.g. Mamba, RNNs)
TITANS = an optimal MIRAS implementation that’s “halfway between” SSM & transformer with a CL memory module

if you're curious about the architecture and mechanics of LLMs, this site has a really excellent explorable interactive visualization. it helps build intuition for how massive these models are, what 'interpretability' means, and the complexity involved here

Solar luminosity around 3.5 billion years ago was only about 70% of what it is right now.
Which means that when life arose on earth, it was outside the sun's habitability zone: liquid water should not have been able to exist.

It seems clear that the current historical moment will have a major impact on culture. Even recent art feels anachronistic. Movies involving govt/cops more obviously, but also just the undertones of social stability. It feels like it meant something different to make music last year. Any art really.
