Delphi-7B-v1: A Specialized Reasoning Model for Healthcare Cybersecurity
Delphi-7B-v1 is a 7.6 billion parameter reasoning model developed by Thaddeus Dickson, CEO of Xpio Health, leveraging 20 years of healthcare cybersecurity and compliance expertise. It is engineered to provide highly specific and direct answers, particularly within the healthcare domain.
Key Capabilities & Features
- Specialized Reasoning: Combines six Qwen 2.5 7B specialist models, including those focused on instruction following, chain-of-thought reasoning, math, and multi-tasking.
- Multi-Stage Training: Undergoes LoRA refinement, SLERP blending, and unique voice SFT (Supervised Fine-Tuning) using hand-crafted domain examples and expert reasoning pairs.
- Domain-Expert Voice: Trained to cite specific standards (e.g., 45 CFR, NIST SP), tools (e.g., Mirth Connect), and codes (e.g., CARC CO-4), connecting technical findings to business impact without hedging.
- Improved Performance: Voice SFT significantly improved IFEval scores from 0.39 to 0.50 (prompt strict), demonstrating enhanced constraint-following.
- Problem-Solving Philosophy: Designed to teach users how to approach problems, not just provide answers, reflecting an "Oracle Philosophy."
Ideal Use Cases
- Healthcare Cybersecurity: Providing specific HIPAA breach notification steps, CFR citations, and compliance guidance.
- Clinical Operations: Assisting with diagnostic frameworks, root cause tracing, and cross-domain problem solving in clinical settings.
- Expert Systems: Applications requiring direct, non-hedging answers with high domain specificity, particularly where regulatory compliance and technical standards are critical.
