Why Fine-Tune MedGemma?

Base MedGemma models excel at conversational coherence, but they are unsuitable for executable medical law. In our testing, they exhibited structural drift and implicit inference—unacceptable for a deterministic auditing engine.

Nexus-Forensic-MedGemma-4B is a specialized LoRA adapter that acts as a Structural Compiler. It translates probabilistic clinical prose (MoH protocols) into strict JSON schemas, generating an executable Knowledge Graph.

Performance Benchmarks vs. Base Model

Trained via our custom TurboForensicTrainer (upsampling EOS tokens by 200%), the compiler eliminates JSON non-termination.

Edge Deployment (GGUF) & Operational Impact

For offline healthcare environments and high-security compliance audits, we physically fused the LoRA weights and compiled an 8-bit quantized artifact (Q8_0) using llama.cpp. This reduces the memory footprint to ~4.1 GB while maintaining 99.1% schema validation.

Data Sovereignty

By running inference entirely on local hospital servers, sensitive Patient Health Information (PHI) never leaves the facility, ensuring strict HIPAA and Data Protection Act compliance.

Zero Cloud Costs

Eliminate variable API costs associated with OpenAI or Anthropic. The GGUF model runs efficiently on standard consumer-grade hardware (e.g., Intel i7 processors) with zero recurring token fees.

Offline Resilience

Rural county hospitals often face intermittent internet connectivity. The Edge model ensures clinical audits and protocol verification can continue without interruption, completely offline.
