Pharma Fine-Tuning Data
Three datasets used across the 3-stage fine-tuning pipeline in llm-finetuning-playbook:
- raw: cleaned paragraphs extracted from the pharma PDF (Stage 1 — continued pretraining)
- instruction: instruction/response pairs (Stage 2 — SFT)
- preference: prompt/chosen/rejected triples (Stage 3 — DPO)
Source corpus: Metformin pharmacology, statin/ezetimibe lipid-lowering therapy, mRNA vaccines, AI in drug discovery, clinical trials & pharmacovigilance.
