Import AI 475: Swarm scaling, Google DeepMind's SynthID Bio watermarking, and the AI science economy

Import AI 475 covers Toby Ord's analysis finding that AI swarms trade roughly twice the tokens for half the wall-clock time, with diminishing returns as agent counts grow. Google DeepMind introduced SynthID Bio, a watermarking family for synthetic biology that matched unwatermarked designs on hit rate and binding affinity across three target proteins. The issue also covers CSAIP polling showing 61% of Americans say voluntary corporate AI commitments are "not enough," and the SciUniverse benchmark of 92 tasks testing how well AI systems operate automated labs.
