Chai-1 holds an Evidaxis momentum score of 64.8 of 100 on methodology m5, snapshot 2026-11-07, measured within the AI Drug Discovery cohort (n = 19). Axis coverage: 1 of 3 axes measurable. Gate: not computable — 1 of 3 axes measurable

Derived signals

second-order reads, computed from the published series

Three signals ship when the commit series is statistically sufficient; the rest are held in a reserved state until the data supports them. A reserved signal shows its reason, never a fabricated number. How these are computed.
