Delphi-7B-v1

Delphi Cyber Pro | Truth wrapped in complexity

The Model

Delphi-7B is a 7.6B parameter reasoning model built for healthcare cybersecurity, clinical operations, and cross-domain problem solving. It combines a 6-model merge of Qwen 2.5 7B specialists with multi-stage training: LoRA refinement, SLERP blending, and voice SFT from expert reasoning pairs.

Built by Thaddeus Dickson, CEO of Xpio Health. 20 years of healthcare cybersecurity and compliance expertise baked into the training data.

This is Chapter 1 of a three-part build. The general model proves the pipeline. What comes next is the point.

Source Models

Model	Role
Homer-v1.0-Qwen2.5-7B	Base. Strongest instruction follower in the 7B bracket.
DeepSeek-R1-Distill-Qwen-7B	Reasoning. Chain-of-thought distilled from DeepSeek-R1.
cybertron-v4-qw7B-MGS	Math and multi-task. Shows up in every competitive 7B merge.
Bespoke-Stratos-7B	Reasoning distillation. 17K clean examples, proven results.
Qwen2.5-Math-7B-Instruct	Pure math specialist.
Qwen2.5-7B-Instruct-Uncensored	Breadth. Says what it means.

Training Pipeline

Stage 1 — Merge. model_stock merge of 6 specialists using mergekit. Homer base provides instruction following, DeepSeek-R1-Distill brings chain-of-thought, cybertron and Math-7B cover quantitative tasks.

Stage 2 — LoRA. Two rounds of LoRA refinement (rank 32, alpha 64) on 8x NVIDIA H100 80GB. Round 1: 5K math samples. Round 2: 5K math + 10K MMLU-Pro + 27 expert reasoning pairs. Preserved IFEval while improving MATH and MMLU-Pro.

Stage 3 — SLERP. Blended full-SFT knowledge model (142K mixed samples, 3000 steps on H100s) with LoRA-refined model. Weight sweep across t=0.25, 0.35, 0.45, 0.55. Winner: t=0.55 — best IFEval + MATH + MMLU-Pro balance.

Stage 4 — Voice SFT. QLoRA on RTX 5090. 308 hand-crafted domain examples teaching direct, specific, no-hedging responses that name exact standards (45 CFR citations, NIST SP references, CARC codes). Combined with 530 Claude-generated IFEval constraint-following examples. This stage transformed the model from generic Qwen output to domain-expert voice.

Expert reasoning pairs carved from a literary background and a poetic mind, infused with 20 years of cyber and software experience. Diagnostic frameworks. Root cause tracing. Cross-domain problem solving.

Scores

Open LLM Leaderboard v2 benchmarks (lm-eval-harness, leaderboard_* tasks, chat template applied):

Benchmark	Score
IFEval (prompt strict)	0.500
IFEval (inst strict)	0.605
MATH Hard	0.187
MMLU-Pro	0.420
BBH	~0.48
GPQA Diamond	~0.31
MuSR	~0.37

IFEval, MATH, MMLU-Pro from full eval on SLERP t=0.55 base. Voice SFT improved IFEval from 0.39 to 0.50 prompt strict. BBH, GPQA, MuSR from LoRA R1 eval.

What Makes Delphi Different

Ask ChatGPT about a HIPAA breach and you get a Wikipedia article. Ask Delphi and you get the specific CFR citations, the exact steps for breach notification, the realistic timeline, and the business impact.

Delphi names specific standards (45 CFR 164.312, NIST SP 800-66), specific tools (Mirth Connect, Prowler, Burp Suite), and specific codes (CARC CO-4, ICD-10). It connects technical findings to business impact. It does not hedge when it knows the answer. It says "I don't know" when it doesn't.

The Oracle Philosophy

The ancient Oracle at Delphi did not give people answers. She gave them frames through which to understand their questions. That is the design philosophy: teach people how to think about the problem, not just what the answer is.
