DeepMind Co-Scientist: A multi-agent AI partner to accelerate research

The detail that reorients the entire Co-Scientist paper: the majority of system compute goes to verifying hypotheses, not generating them. DeepMind didn't build a research assistant on top of Gemini — it built a verifier corpus (AlphaFold, ChEMBL, UniProt, the full literature stack) and wrapped a generator around it. That architectural choice is the same bet surfacing in the Bloomberg litigation data and the BBC manipulation piece: generation is cheap and increasingly generic, and the organizations that accumulated verification infrastructure before the model layer commoditized are holding the durable position. Every 'AI for vertical X' startup that priced the model layer priced the wrong thing. The moat was always the corpus that tells you whether the output is true.
