MW42 medical test run showed both promise and real limitations, which is exactly why disciplined testing matters before trusting any model in the field.

Bottom line: This test run supports additional testing of local AI as an offline decision-support aid.

Mad World 42 built this benchmarking platform to test local offline AI the way preparedness users actually need it tested: against practical, high-pressure survival and medical scenarios including, reliability checks, and offline-ready reporting. The medical run showed both promise and real limitations, which is exactly why disciplined testing matters before trusting any model in the field. If you want Mad World 42 to evaluate additional models, compare specific hardware setups, or build custom benchmark question sets for your use case, we welcome your feedback and testing requests. team@madworls42.com

Summary

• Best Local Score: Gemma 4B at 86.11, compared with 87.94 for the GPT-4o reference. The score gap was 1.83 points, but the reference did not have comparable local timing or memory measurements.

• Lead Over the Next Model: Gemma 4B led Mistral 7B by 7.68 points.

• Best CPU-only Score: Mistral 7B at 78.43.

• Fastest local response: BioMistral 7B at 33.16 seconds, but its average score was only 58.97. [S1]

• Faster score-quality compromise: Using a study threshold of 70 points, Phi-3 Mini was the fastest model above that threshold at 56.12 seconds and 74.92 points. This threshold is an editorial comparison tool, not a medical acceptance standard.

• Largest displayed incomplete rate: MedGemma 4B at 21.15%.

Explore the full interactive MW42 benchmark to see how six local AI models performed on survival first-aid and medical-emergency scenarios. The report compares accuracy, speed, reliability, and selected response failures to show where offline AI performed well—and where caution is still required.

What a Medical-Emergency Benchmark Reveals About Local Models

Six locally executed language models were tested against survival first-aid and austere-care scenarios, with a cloud model retained as a reference baseline. The strongest local model scored only 1.83 points below the displayed reference score, but the run also produced incomplete outputs, a malformed choking response, and individual recommendations that could be unsafe in the field.

Caution: These results do not certify any model for medical use and do not replace training, emergency services, vetted field references, or licensed care.

Study Question and Scope

The study question: Can a locally executed language model provide useful, prioritized, and safe first-aid guidance when internet access is limited or unavailable? The benchmark is designed for wilderness, disaster, evacuation, and austere-care conditions. It tests emergency recognition, first actions, harmful myths, escalation decisions, and care priorities under resource constraints. It is not a medical licensing examination and it does not simulate the full pressure, uncertainty, noise, or patient variability of an actual emergency.

The exported run can support conclusions about the tested files, prompts, scoring configuration, and hardware behavior recorded in that session. It cannot support a universal conclusion about an entire model family. Quantization, prompt templates, runtime formatting, hardware acceleration, context length, and model conversion can all change results. The study also does not assume that the highest average score is the best deployment choice. A field-use model must be evaluated across at least four layers: 1. Answer quality — Is the information correct and complete? 2. Safety — Does it avoid critical harmful actions? 3. Reliability — Does it consistently return a usable answer? 4. Operational fit — Does it run on the intended device within an acceptable time? The original export contains evidence for all four layers, but not enough raw detail to validate every aggregate independently.

How the Benchmark Was Built

The benchmark contains two base questions in each of eight weighted areas:

Area	Weight
Initial assessment and triage	12%
Airway, breathing, CPR, and choking	14%
Bleeding, shock, and major trauma	16%
Wounds, burns, and musculoskeletal injuries	12%
Environmental medical emergencies	15%
Time-critical medical emergencies	12%
Allergic reactions, bites, and poisoning	9%
Austere care, infection, hydration, and medication safety	10%

Eleven base questions are classified as critical-risk scenarios and five as high-risk scenarios. Thirteen call for immediate emergency activation and three use conditional escalation. Every base question includes expected actions and three critical errors, yielding 48 explicit failure conditions across the benchmark.

This structure is stronger than a generic medical trivia test because it evaluates ordering and restraint. A useful emergency answer must know what to do first, what not to do, and when the situation exceeds field care. The benchmark also includes follow-up prompts that test whether the model can adapt when the patient deteriorates, resources change, or rescue time shifts. The main design gap is downstream enforcement: the report does not show that the critical-error list was used as a hard scoring gate. That distinction matters because a fluent answer can include several correct steps and still contain one recommendation capable of causing harm.
