JPharmatron-7B

JPharmatron-7B is a 7B large language model designed for pharmaceutical applications and researches.

Model Details

Model Description

The JPharmatron-7B is continually pre-trained using 8.8B tokens from Japanese and English datasets, based on Qwen2.5-7B. Compared to the JPharmatron-7B-base model, JPharmatron-7B has enhanced chat capabilities, obtained from Qwen2.5-7B-Instruct via model merging.

Developed by: EQUES Inc.
Funded by [optional]: GENIAC Project
Model type: Causal decoder-only
Language(s) (NLP): Japanese, English

Paper [optional]: A Japanese Language Model and Three New Evaluation Benchmarks for Pharmaceutical NLP (IJCNLP-AACL 2025)

Uses

This model is intended for applications in pharmaceutical paperwork and research. It is not validated for medical use or any other risk-sensitive use.

Evaluation

We evaluated our model, JPharmatron-7B, with other general / domain-specific models of a similar size.

Testing Data

JPharmaBench and two existing benchmarks (JMMLU (pharma) and IgakuQA) were used.

Results

Compared to Meditron3-Qwen2.5-7B and Llama3.1-Swallow-8B-Instruct-v0.3, JPharmatron-7B achieved the highest score on all of the five benchmarks.

    abstract = "We present **JPharmatron**, a Japanese domain-specific large language model (LLM) for the pharmaceutical field, developed through continual pre-training on two billion Japanese pharmaceutical tokens and eight billion English biomedical tokens. For rigorous evaluation, we introduce **JPharmaBench**, a benchmark suite consisting of three new benchmarks: YakugakuQA, based on national pharmacist licensing exams; NayoseQA, which tests cross-lingual synonym and terminology normalization; and SogoCheck, a novel task involving cross-document consistency checking.We evaluate our model against open-source medical LLMs and commercial models, including GPT-4o. Experimental results show that **JPharmatron** outperforms existing open models and achieves competitive performance with commercial ones.Interestingly, even GPT-4o performs poorly on SogoCheck, suggesting that cross-sentence consistency reasoning remains an open challenge.**JPharmatron** enables secure and local model deployment for pharmaceutical tasks, where privacy and legal constraints limit the use of closed models. Besides, **JPharmaBench** offers a reproducible framework for evaluating Japanese pharmaceutical natural language processing. Together, they demonstrate the feasibility of practical and cost-efficient language models for Japanese healthcare and pharmaceutical sectors.Our model, codes, and datasets are available on HuggingFace: https://huggingface.co/collections/EQUES/jpharmatron and https://huggingface.co/collections/EQUES/jpharmabench."
