ESM3Runner

ferritin_plms::esm3::pretrained

Struct ESM3Runner 

Source 
pub struct ESM3Runner { /* private fields */ }
Expand description

Wraps a loaded ESM3 model for sequence embedding and multi-track inference.

§HuggingFace access

The ESM3 model is gated. Before calling from_pretrained the user must:

  1. Accept the Cambrian Non-Commercial license at https://huggingface.co/EvolutionaryScale/esm3-sm-open-v1
  2. Run huggingface-cli login (or set HF_TOKEN env var)

Implementations§

Source§

impl ESM3Runner

Source

pub fn from_pretrained(variant: ESM3Models, device: Device) -> Result<Self>

Download the ESM3 weights from HuggingFace and load the model.

The .pth checkpoint is loaded directly via candle_core::pickle::PthTensors.

Source

pub fn embed_sequence(&self, sequence: &str) -> Result<Tensor>

Tokenize sequence and return per-residue embeddings (1, L, d_model).

Only the sequence track is provided; all other tracks are None. Embeddings are the pre-norm transformer hidden states (raw activations).
