Haven't seen it on Bluesky yet: a nice paper is making the rounds, estimating that the cost of housing permits in LA can explain 1/3 of the gap between construction costs and housing prices.

That is: LA's terribly slow housing permitting is extremely costly!

We’ve identified industrial-scale distillation attacks on our models by DeepSeek, Moonshot AI, and MiniMax.

These labs created over 24,000 fraudulent accounts and generated over 16 million exchanges with Claude, extracting its capabilities to train and improve their own models.

What made my day here is that they got no sympathy even on Muskrat's platform lol. And unlike Anthropic, deepseek is paying for model use when they do this, to create models that are open weight. They're showing how this entire bubble is being propped up by the equivalent of a toothpick.

Putative solutions include injecting artificial noise to public data to neutralize such malicious attempts. The cost? obviously less precision. I have some mixed thoughts about it, but it's certainly better to be aware of issues than to remain oblivious.

I attended Prof. GΓΌrsoy's talk during last year's probgen and the claims were scary. You can literally reverse-engineer GWAS summary statistics and public single-cell RNA-seq data to identify subjects.
