molcrawl-protein-sequence-proteingym-gpt2-small

Model Description

GPT-2 small (124M parameters) fine-tuned on ProteinGym protein sequence data, starting from the molcrawl-protein-sequence-gpt2-small pre-trained model.

Datasets

ProteinGym: https://proteingym.org/ (Fine-tuning dataset)
Model Type: gpt2
Data Type: Protein
Training Date: 2026-04-24

Usage

python

from transformers import AutoModelForCausalLM, AutoTokenizer
import torch

model = AutoModelForCausalLM.from_pretrained("kojima-lab/molcrawl-protein-sequence-proteingym-gpt2-small")
tokenizer = AutoTokenizer.from_pretrained("kojima-lab/molcrawl-protein-sequence-proteingym-gpt2-small")

# Generate protein sequence
prompt = "MKTAYIAKQRQISFVKSHFSRQLEERLGLIEVQAPILSRVGDGT"
inputs = tokenizer(prompt, return_tensors="pt")
with torch.no_grad():
    output_ids = model.generate(
        **inputs,
        max_new_tokens=50,
        do_sample=True,
        temperature=0.8,
        eos_token_id=None,  # HF config.json has legacy eos_token_id=0; disable early stop
        pad_token_id=0,
    )
print(tokenizer.decode(output_ids[0], skip_special_tokens=True))
