Liquid AI's LongevityBench: compact LFMs beat frontier models on several aging tasks

JosephJacks_ · x · 2026-10-01

Liquid AI and InSilico Medicine launched LongevityBench, a new aging benchmark testing models on 17 tasks across clinical records, DNA methylation, transcriptomics, proteomics, and genetics.

On several tasks, Liquid AI's compact LFMs outperformed every frontier model evaluated. Researcher Katerina Nasto and CTO Mathias Lechner discuss how the benchmark was built, why leakage-proof evaluation matters, and how specialized models running locally on sensitive patient data could help researchers move from prediction to better hypotheses and experiments.

The team will present at the ARDD longevity meeting this week; blog, model, and paper are available.
