AI co-scientist
Multi-agent Gemini 2.0 system that generates, debates and Elo-ranks research hypotheses; reports wet-lab support in leukaemia drug repurposing and liver-fibrosis targets.
Generation, reflection, ranking, evolution and meta-review agents loop with test-time compute; the self-assigned Elo rating correlates with GPQA-diamond accuracy. It independently proposed an unpublished bacterial-phage mechanism (cf-PICI) that the originating lab had already confirmed in experiments.
