VetJarvis-4B-Instruct: Domain-Specific Veterinary LLM
VetJarvis-4B-Instruct, developed by CHOONOK COMPANY, is a 4.5 billion parameter instruction-tuned model built on the Qwen3.5 architecture. It is uniquely specialized for companion animal (canine and feline) veterinary knowledge, education, and AI research. A key differentiator is its enhanced reasoning performance through an improved post-training pipeline, particularly when its thinking mode is activated, which allows it to achieve performance comparable to GPT-5.4-mini.
Key Capabilities & Features
- Domain Specialization: Highly proficient in veterinary medicine, trained on de-identified clinical data and reference materials.
- Enhanced Reasoning:
thinkingmode significantly boosts performance on complex veterinary reasoning tasks. - Benchmark Performance: Outperforms similarly sized open local models (e.g., Qwen3.5-4B, Gemma-E4B) by 15-25 percentage points on the Japanese Veterinary National Examination benchmark, narrowing the gap to leading closed models like GPT-5.4-mini.
- Multilingual Support: Supports both Korean and English languages.
- Context Length: Features an 8,192-token context window for SFT.
Good For
- Veterinary Research & Education: Ideal for academic studies and educational purposes in veterinary science.
- Responsible AI Development: Supports the advancement of safe and responsible AI technologies in the veterinary field.
- Specialized Knowledge Retrieval: Excels in areas like hematology/oncology, orthopedics, endocrinology, and clinical decision-making within veterinary contexts.
Limitations
It is crucial to note that VetJarvis-4B-Instruct is not a medical device and is not permitted for clinical use to replace professional veterinary judgment. Users must be aware of potential hallucinations and knowledge cutoff limitations (April 2026).
