The Dynamics Data Engine Powering Predictive BioAI

Biology has a
token problem.

LLMs took off when the right data achieved scale: trillions of tokens. BioAI is lagging because no one has defined the fundamental tokens for living systems — until now. Base4 generates at scale the foundational data needed to drive a throughline from molecules to a full human model.

Atomic Tokens:
Fundamental units of the molecular language

Every biological process happens at the atomic level. We built a data factory that generates Atomic Tokens at scale: physics-grounded, time-resolved data capturing how each atom behaves. This is the data layer biology has been missing and is the foundational unit to tie together multiple scales of the living system.

The Atomic Foundation is Being Laid Now

Enabling a throughline to virtual cells...
and eventually a complete human model.

Atomic Tokens are the data that make foundation models for living systems possible. Now, AI can learn how molecules behave, interact, and respond, building predictive insights across novel biological pathways, drug discovery, disease understanding, synthetic biology, foundation modeling ... the limits are unknown.

Disease Modeling
Understand the molecular effects and pathological drivers at the atomic level.
Drug Discovery
Predict how any biomolecule and drug will behave, engage and interact.
Foundation Model Training
Train AI with the atomic data it needs to reason about biology.
