RexDrug-Base

This is the SFT (Supervised Fine-Tuning) base model for RexDrug, a chain-of-thought reasoning model for biomedical drug combination relation extraction.

Model Details

  • Base architecture: Llama-3.1-8B-Instruct
  • Fine-tuning method: SFT with LoRA (merged)
  • Task: Drug combination relation extraction from biomedical literature
  • Relation types: POS (beneficial), NEG (harmful), COMB (neutral/mixed), NO_COMB (no combination)

Usage

This model is intended to be used with the RexDrug-adapter (LoRA adapter trained via GRPO). See the adapter repository for the full quick start guide.

    device_map="auto",
)
model = PeftModel.from_pretrained(model, "DUTIR-BioNLP/RexDrug-adapter")
