What it is

ESM3 is a frontier multimodal generative protein model trained on 2.78B proteins that can be prompted across sequence, structure and function simultaneously — 'programming' biology like code. To showcase it, the team generated esmGFP, a fluorescent protein ~58% distant from any natural one, equivalent to ~500M years of evolution. Founded by ex-Meta FAIR researchers; acquired by Chan Zuckerberg Biohub in 2025.

Connected research frontiers

These records describe active research directions, not guaranteed capabilities of this model. Evidence stages and unresolved questions are preserved separately.

Generative biomolecular design

Multimodal protein programming

EvolutionaryScale · 2025-01-16
Peer-reviewed capability

Can one generative model reason jointly over protein sequence, structure and function and create functional proteins from mixed prompts?

Evidence boundary and unresolved questions

One striking protein demonstration does not establish general success across enzymes, therapeutics or complex multi-objective design tasks.

  • How frequently do generated functions survive experimental testing?
  • Can the model optimize potency, stability and safety together?
  • How should synthetic training labels affect confidence?

Prospective de novo binder generation

Google DeepMind · 2024-09-05
Prospective demonstration

Can AI generate high-affinity protein binders for diverse targets with fewer rounds of experimental optimization?

Evidence boundary and unresolved questions

Performance varies by target; the system did not succeed on every attempted target and is not publicly released for unrestricted reproduction.

  • Which target properties predict designability?
  • How transferable are success rates to membrane and flexible targets?
  • Can developability, immunogenicity and function be optimized jointly?

Scientific lineage

Explore all foundations

These are transparent concept matches—not claims that one scientist alone caused this model. Each connection is based on the model’s recorded domain, scientific principles, technical terms or an explicit lineage link.

Structural biology

Anfinsen’s dogma—the thermodynamic hypothesis

Christian B. Anfinsen

Protein structure prediction, inverse folding and generative protein design all assume that sequence strongly constrains structure and function.

Explicit model lineage
Computational intelligence

Transformer self-attention

Ashish Vaswani and colleagues

Protein, genome, molecule and single-cell foundation models use attention to learn dependencies across biological sequences and multimodal inputs.

Matched concepts: transformer, language model, sequence
Computational intelligence

Information, entropy and communication

Claude E. Shannon

Sequence modelling, cross-entropy training, language models, mutual information and representation learning all use Shannon’s framework.

Reading the sequences of proteins and DNA

Frederick Sanger

Biological foundation models exist because proteins and genomes became readable, comparable and computable at scale.

Reported multimodal generation includes an experimentally characterized designed protein.

Claim caveats
  • A demonstration protein is not a universal measure of design performance.
  • Hosted and open variants may differ in capability and access.

Known limitations

  • Performance depends on the evaluation dataset and operating conditions.
  • Task-specific benchmark results should not be compared across unlike domains.
  • Outputs require task-specific scientific and experimental validation.
