ESM: Evolutionary Scale Modeling

Overview

ESM provides protein language models for understanding, generating, and designing proteins. Use this skill for current EvolutionaryScale/Biohub workflows: ESM3 for generative design, ESMC for representation learning and embeddings, hosted Forge/Biohub inference, and ESMFold2 all-atom structure prediction.

Core Capabilities

1. Protein Sequence Generation with ESM3

Generate novel protein sequences with desired properties using multimodal generative modeling.

When to use:

• Designing proteins with specific functional properties
• Completing partial protein sequences
• Generating variants of existing proteins
• Creating proteins with desired structural characteristics

Basic usage:

from esm.models.esm3 import ESM3
from esm.sdk.api import ESM3InferenceClient, ESMProtein, GenerationConfig

# Load local open weights after accepting the license on Hugging Face.
model: ESM3InferenceClient = ESM3.from_pretrained("esm3-open").to("cuda")

# Create protein prompt
protein = ESMProtein(sequence="MPRT___KEND")  # '_' represents masked positions

# Generate completion
protein = model.generate(protein, GenerationConfig(tr…
