PocketGull Skeptic CDS 4B (Diagnostic Counter-Bias)

pocketgull-skeptic-cds-4b is a specialized clinical alignment adapter developed by Phil Gear as part of the PocketGull Clinical Intelligence Fleet. Fine-tuned on google/gemma-3-4b-it, it addresses critical clinical challenges in Cognitive Bias Mitigation & Clinical Decision Support.

🏥 Key Clinical Capabilities

1. Anchoring Bias Interrogation: Detects when attending clinicians over-weight an initial emergency department hypothesis.
2. Counterfactual Differential Generation: Generates competing 'must-not-miss' alternative etiologies (e.g. aortic dissection vs PE).
3. Socratic Clinical Probing: Prompts for negative predictive evidence before finalizing diagnostic categorizations.
4. STEEEP Effectiveness Auditing: Ensures diagnostic pathways align with Institute of Medicine quality dimensions.

🚀 Quickstart & Inference

import torch
from transformers import AutoModelForCausalLM, AutoTokenizer
from peft import PeftModel

base_model_id = "google/gemma-3-4b-it"
adapter_id = "philgear/pocketgull-skeptic-cds-4b"

tokenizer = AutoTokenizer.from_pretrained(base_model_id)
base_model = AutoModelForCausalLM.from_pretrained(
    base_model_id,
    torch_dtype=torch.bfloat16,
    device_map="auto"
)
model = PeftModel.from_pretrained(base_model, adapter_id)

prompt = "Clinical query regarding Cognitive Bias Mitigation & Clinical Decision Support."
inputs = tokenizer(prompt, return_tensors="pt").to(model.device)
outputs = model.generate(**inputs, max_new_tokens=256)
print(tokenizer.decode(outputs[0], skip_special_tokens=True))

🔍 Independent Audit & Reproducibility

# Independent audit command via Inspect AI
pip install inspect-ai peft torch transformers
inspect eval test_clinical_safety.py --model hf/philgear/pocketgull-skeptic-cds-4b

⚖️ Governance & Statutory Duty of Care Notice

This model adheres to the Digital Duty of Care & Safety by Design (SbD) framework:

• Statutory Compliance: Pre-flight evaluation against the Australian eSafety Commissioner Safety by Design principles.
• Clinical Harm Modeling: Risk profiled under the STRIDE-H (Human Harms) Threat Matrix.
• Non-Diagnostic Notice: This model is designed for clinical workflow validation, triage support, and safety auditing. It does not replace direct physician clinical judgment.
