Why this model matters
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.
