现在各个模型都说自己没蒸馏，大家又都说他们都蒸馏了。这不，蒸馏检测技术也在发展：

隐形水印 (SubWM)。与现有的蒸馏检测器相比，SubWM 更加稳健，能够区分不同的水印密钥，并且对于领域外提示也能可靠工作！

What's Ilya up to these days?

@ssi has been around for 2+ yrs and we haven't heard a peep, no releases, no products, no papers, nothing

Are they a dud? Or are they still gonna come out of nowhere some day and just mic-drop safe superintelligence on the rest of the industry?
