🦠 Flu Virus Foundation Model

This is a foundation model trained on influenza virus sequences for predicting viral evolution, functional constraints, and potential antigenic changes.
It is designed to support research in influenza biology, vaccine design, and immunology.

📖 Model Details

Model type: Transformer-based language model
Architecture: GPT-2 style
Framework: 🤗 Transformers (PyTorch)
Files included: model weights (model.safetensors), tokenizer, config files
Trained on: pretrained on GISAID and NCBI influenza A sequences; finetuning on Noncoding region sequence completion

🚀 Simple Usage

python

from transformers import AutoTokenizer, AutoModelForCausalLM
import torch

# Model and tokenizer from Hugging Face Hub
model_name = "Yiquan2/Flu_Foundation"
tokenizer = AutoTokenizer.from_pretrained(model_name)
model = AutoModelForCausalLM.from_pretrained(model_name)

# Example input sequence (DNA/protein)
sequence = "ATGAATCCAAACCAGAAAATAATAACCATTGGCTCTGTT"

# Tokenize input
inputs = tokenizer(sequence, return_tensors="pt")

# Generate output probabilities or predictions
with torch.no_grad():
    outputs = model(**inputs)
    logits = outputs.logits  # shape: [batch_size, seq_len, vocab_size]

# Optional: compute probabilities
probs = torch.softmax(logits, dim=-1)

print(probs)
