Self‑evolving Life Operators, toward full‑scale life simulation.

We build Life Operators — a unified computational framework that models, simulates and updates the dynamics of life across scales: cell, tissue, organ, patient.

Life is computable. Medicine, super‑evolved.

01 · Vision

Medicine’s next leap is from AGI to ASI.

The step change in medical intelligence is not better recognition or better answers — it is the ability to perceive, model and simulate the processes of life itself.

ANI

Narrow medical intelligence

Single-point perception tools.

  • Lung-nodule detection
  • Fundus image diagnosis
AGI

General medical intelligence

Understanding and autonomous reasoning.

  • AI consultation
  • Agentic doctors
ASI

Super medical intelligence

Life simulation, across every scale.

  • Treat disease before it arrives
  • One person, one medicine
“Medicine will no longer be content to see disease that has already happened — it will simulate the living system, and rehearse the trajectory of disease before it truly arrives.”Junbo Ge · Academician, Chinese Academy of Sciences · Cardiology
“With data and AI we are, in essence, building a virtual twin of the patient. When the model is reliable enough, we can simulate the effect of a drug — alone or in combination.”Olivier Elemento · Englander Institute for Precision Medicine, Weill Cornell
“Map every patient to a digital twin in the cloud, and you can run safe simulations on the patient’s own data before touching the real treatment system.”Boris Kovatchev · Founding Director, UVA Center for Diabetes Technology

02 · The gap

Prediction is not simulation.

Today’s frontier — Delphi‑2M, ALADYNOULLI, Oncoformer — learns the statistics of clinical records. Impressive, and far from life simulation: statistical sequence models see the chart, not the cross‑scale dynamics of the living system that produced it.

Sequence prediction

What happens next

  • Learns token statistics from medical records
  • Forecasts risk, prognosis, next event
  • Cannot say why — or what an intervention changes

Life simulation

Why it happens — and what changes after intervention

  • Models latent life state across molecule, cell, tissue, organ, body
  • Evolves that state under natural dynamics and treatment
  • Closes the loop against new observations
Missing: cross‑scale stateMissing: evolutionary dynamicsMissing: medical interventionMissing: closed‑loop validation

03 · Framework

One framework, every scale of life.

Molecular dynamics, virtual cells, virtual tissue, organ and patient digital twins each live at their own point in space and time. The Life Operator is the single mathematical object that connects them.

  • Mechanistic laws

    PDE · ODE · reduced-order models

  • Data-driven laws

    Flow matching · Koopman · neural operators

  • Sequential update

    Bayesian filtering · smoothing

Chart of temporal versus spatial scale: molecular dynamics, virtual cell, virtual tissue, organ digital twin and patient digital twin, unified by Life Operators across scales

One framework across temporal and spatial scales.

04 · The science

Life as a dynamical system.

Multimodal observations infer a latent life state; operator dynamics evolve it — under aging, disease and treatment — and generate the observable signals of the future.

Observations

Y≤t, U<t, C≤t

Imaging · signals · omics · pathology · wearables · labs

Latent life state

Zt

Cell · tissue · organ · whole-body state

Dynamics

Żt = f (Zt, Ut, Ct)

Aging · disease onset · intervention · recovery

Future trajectory

Yt+Δt ~ p(·|Zt+Δt)

Signals and phenotypes, forward in time

Three medical questions — what is happening now, what is likely to happen next, and what would change under intervention — asked across molecular, cellular, tissue, organ and individual scales, each with representative interventions

Three questions of medicine — the current state, the natural course, and what changes under intervention — asked at every biological scale.

05 · Self-evolution

Operators that improve themselves.

AI4AI: agentic Auto‑Research replaces linear R&D, and a real‑world data flywheel keeps every operator evolving after deployment.

Auto-Research

One scientist, 100× agents

Literature, data, hypothesis, operator-design and validation agents discover, build, verify and upgrade Life Operators — recursively — from large-scale historical data.

  • Hypothesis generation → data organization
  • Operator optimization → validation → composition → upgrade

Data flywheel

Real-world feedback, closed loop

Every delivered project returns data to the operator system: governance → design → training & simulation → validated delivery → real-world use → data return.

  • Harder operators, broader capability
  • Faster feedback, fuller system

06 · Evidence

Warm‑started with clinical‑scale proof.

Life Operators are not starting cold. Disease-specific programs in renal cancer and cardiology have already closed the loop from data to model to validation.

12,809renal-cancer patients
3.5M+ECG recordings
0.871AUC, benign vs. malignant (RenalCLIP)
1000×faster than FEM (Cardio-Solver)
20,000+digital pathology slides

Renal program

RenalCLIP — a disease-specific foundation model

Outperforms radiomics, clinical scoring and general CT foundation models; surpasses specialist urological radiologists on small renal-mass differentiation.

Cardiac program

A data–solver–simulation loop for the heart

Million-scale multimodal cardiac data, neural-operator solvers, aging trajectories reproduced across three cohorts, and commissioned virtual clinical trials validated against Phase I results.

07 · Applications

Simulation opens new ground for medicine.

Drug R&D

  • Clinical-trial design
  • Indication & population selection
  • Efficacy probability & extrapolation boundaries

Device R&D

  • Structure–function–intervention simulation
  • Plan comparison & virtual validation
  • Risk-boundary definition

Treatment decisions

  • Patient-state reconstruction
  • Intervention comparison & MDT support
  • Disease-course simulation

Health management

  • Risk trajectories & follow-up cadence
  • Intervention advice & long-term tracking
  • Natural-aging simulation

08 · The system

One computation graph, from cells to the whole body.

Every scale of life carries its own latent state. Life Operators couple those states — represent, evolve, generate, update — into a single whole‑body computation graph that simulates the future.

The Life Operator system: cell, tissue and organ latent states coupled through multiscale representation, cross-scale coupling, dynamical evolution and Bayesian updating, driving whole-body simulation of future trajectories

Latent life states

Cell, tissue and organ each hold their own latent space — Zcell, Ztissue, Zorgan — with its own representation and dynamics.

Operator primitives

Multiscale representation, cross-scale coupling, dynamical evolution and Bayesian updating — composed as perception, transformation and generation operators.

Whole-body simulation

Coupled organs form the full-scale computation graph: from state t0, simulate the future trajectory — risk, intervention, outcome.

Next milestone

Cardio‑World — the full‑scale cardiac simulation model

The heart is where multi-scale simulation breaks through first: clear clinical demand, million-scale data, well-understood physics, and a short path to validation. Cell electrophysiology, tissue conduction and organ hemodynamics, coupled up‑scale and inverse.
