Equi-mRNA Foundation Model
The first codon-level equivariant mRNA language model. SO(2) symmetry-aware architecture that outperforms traditional models on expression prediction, stability assessment, and sequence generation.
The Timing Is Right
AI Co-Scientist Validated
Google proved the model works — but went horizontal. We go vertical on mRNA where depth matters most.
mRNA Beyond Vaccines
The pipeline is exploding into protein replacement, gene editing, and personalized cancer medicine — each needing better optimization.
Foundation Models at Scale
For the first time, language models can learn biological language at scale. Equi-mRNA adds the missing physics — codon symmetry.
SO(2) Equivariant Codon Encoding
mRNA codons encoding the same amino acid are synonymous — they share function but differ in sequence. Traditional models ignore this. Equi-mRNA explicitly encodes these symmetries as cyclic subgroups of SO(2).
By integrating group-theoretic priors with an auxiliary equivariance loss and symmetry-aware pooling, the model learns biologically grounded representations that capture what matters: function, not just sequence.
Validated: the model learned real biology
Learned codon rotations correlate with GC-content biases (r=0.98, R²=0.97) and tRNA abundance patterns (ρ=−0.69) — confirming the model captures known biological constraints, not just statistical patterns.
How Equi-mRNA Works
The Codon Optimization Crisis
The mRNA therapeutics market is projected to grow from $6B to $20.4B by 2032. But expansion beyond vaccines faces a fundamental computational bottleneck.
Pain Points Equi-mRNA Solves
Why Equi-mRNA Is Different
All existing approaches treat codon selection as a discrete combinatorial, sequence generation, or frequency lookup problem. None exploit the mathematical group structure of the genetic code itself.
| Approach | Method | Limitation | Equi-mRNA Advantage |
|---|---|---|---|
| LinearDesign (Baidu) | Lattice parsing from linguistics | Optimizes only MFE + CAI; no frameshifting awareness | Multi-objective with safety constraints |
| GEMORNA (Raina Bio) | Transformer-based generative model | Black box; requires retraining per application | Interpretable, symmetry-grounded |
| RNop (2025) | Deep learning with 4 loss functions | Limited by training distribution (3M sequences) | Physics-informed inductive bias |
| GenSmart (GenScript) | Frequency tables only | No structure awareness | Holistic multi-property optimization |
