Key Points

  • The article argues that many biology foundation models struggle because they treat single-cell data as static snapshots rather than capturing temporal aging trajectories.
  • It introduces “MaxToki,” an AI approach intended to predict how cellular states progress with age from single-cell transcriptomic inputs.
  • The piece positions the model as a way to move from “what a cell is doing now” toward “how it is likely to change,” potentially enabling actionable insights about aging biology.
  • It frames the broader challenge for AI in biology as incorporating time dynamics and biological progression into model training and representation.
  • It suggests that model outputs could be used to guide interventions, implying practical downstream value beyond descriptive analysis.
  • Point 5
  • Point 6

Most foundation models in biology have a fundamental blind spot: they see cells as frozen snapshots. Give a model a single-cell transcriptome — a readout of which genes are active in a cell at a given moment — and it can tell you a lot about what that cell is doing right now. What it […]
