Suppose an AI model fully automates a $200k job. Its economic value - measured in contribution to GDP - will be both far more and far less than $200k. There are two ways of thinking about the model's economic value: (1) It'll be far more than $200k. After all, the human

Very exciting to see more work on benchmarking long-horizon CUAs! IMO there's only two main challenges remaining until CUAs become mainstream and productionizable: (1) effective long-horizon agents and (2) fast/realtime CUAs. I think we are going to get there very soon.

Susan Zhang @suchenzang 2026-06-26 02:45Z

these people want ai models to be treated like nuclear weapons, researchers treated like they own nuclear state secrets during ww2, and geopolitical tensions escalated until we get ww3, where all production power can then be seized for the "ai industrial revolution" they strive

If we look at the percent of unhoused homeless as a percent of the US total population, we see a shocking stability across time and our current homeless population is returning to the pre-Millennial dip of the 2010s. That makes me wonder if there is a kind of min-max

Why was the denazification of West Germany so successful? Arguably, it's because it was antidemocratic. If the Western Allies had immediately held free elections after the war, they might just have produced another fascist government. But instead, the Allies transferred power

Nemotron 3 Ultra uses a shared-weight MTP head that allows the same head to be applied recursively for drafting. However, for this to work, it requires a separate "MTP Boosting" phase—on-policy distillation phase—so that the model learns to react to drifts in hidden states not
