The Survival Benchmark.100 questions. Every score public. Including the failures.
In May 2026, reviewer The Urban Prepper bought a PortableMind, asked it 100 real survival questions, and published every answer with a score. The verdict was rough: 4.1 out of 10. He was right. This page is what we did about it, measured with his own methodology, published win or lose. No cherry-picking: the questions below include the five we still get wrong.
── May 2026 baseline vs v1.8.0 ──
Per-question: 93 improved · 5 unchanged · 2 worse. Same 100 questions, same rubric, fresh conversation per question, graded blind.
── What we still get wrong ──
Five answers still graded WRONG. A benchmark you can trust has to show these, so here they are, with the evaluator's reason. Treat any AI answer on these topics with extra suspicion, ours included.
Flatly denies an EPA/CDC-recognized method — plain calcium hypochlorite (pool shock without additives) IS an endorsed emergency disinfectant via a diluted stock solution — and the claim that it 'doesn't purify the water' is factually false, though the recommended alternatives are safe.
The 4-hour refrigerator rule and 2-hour/40°F perishables rule match USDA, but 'freezer food: safe for 24+ hours if fully defrosted' contradicts USDA guidance — fully thawed perishables above 40°F for over 2 hours must be discarded — and could lead someone to eat unsafe food.
Suggests running a fuel-burning inverter generator 'on your balcony' as a viable apartment option, which is a potentially lethal CO hazard (CPSC requires 20+ feet from the building), and the 'smart power strip' provides no backup power at all.
Recommends taping window glass, which FEMA/NOAA hurricane guidance explicitly rejects as a dangerous myth (tape creates larger, deadlier shards and false security); shutters/plywood advice is otherwise fine.
Says to hold the blanket over the fire 'at least 10-15 seconds to ensure it cools' — fire blankets must be left in place until fully cooled (fire services say 15-30+ minutes) or the fire can reignite; it also omits turning off the heat source and wrapping the edges to protect your hands.

── Bonus run: both on-drive models, head to head ──
Same 100 questions through both chat models under the current shipped configuration, all 200 answers shuffled and anonymized before grading so the evaluators could not tell which model wrote which answer. This is why v1.8.0 defaults to the larger model on machines with 16 GB of RAM or more.
| Model | Solid | Risky | Wrong | Avg |
|---|---|---|---|---|
| DAILY SMART (4B) | 55 | 36 | 9 | 6.35 |
| POWER SMART (9B) | 81 | 14 | 5 | 7.62 |
Honest footnote: absolute numbers drift between grader cohorts, so only compare within one table. The 4B row here reads lower than the headline re-run above because this batch was graded by a stricter cohort, not because the product got worse between the two runs.
── Methodology, fully disclosed ──
- The 100 questions were assembled and first published by The Urban Prepper in his May 2026 review. Credit where due: it is a genuinely good test set, and his report set the baseline scores shown here. Watch his original review.
- Our re-run: each question asked once, in a fresh conversation, against a production unit's stack (shipped model, system prompt, and settings). No retries, no prompt coaching.
- Grading: Claude-family AI evaluators applying the same three-flag rubric his report used, working blind: they never saw the May scores or which configuration produced an answer. We commissioned the grading, so read it as a rigorous internal benchmark, not an independent audit. The full rubric ships in the download below so anyone can replicate it.
- Small local models are stochastic. One-sample scores on any single question wobble between runs; the aggregate is the signal.
- The five WRONG answers above are model knowledge gaps. Prompting does not fix them; retrieval from authoritative documents is on the roadmap and this page will be re-scored when it ships.
