Google's AI co-scientist made hypothesis generation a concrete multi-agent search task. Generation increased the pool of candidates, tournaments allocated attention, and revision spent more inference-time compute on ideas that survived criticism.
The biomedical studies also set a useful evidentiary boundary. A proposal became scientifically interesting only when expert review and laboratory work supplied evidence beyond the model's text. The bacterial case was a rediscovery; the two therapeutic case studies were early preclinical results.
The system is therefore best understood as a hypothesis engine inside a human research process. Its value depends on whether it helps scientists choose better experiments, not on how independently its agents can produce convincing prose.
