Impact of Scaffolds on AI Safety
Our study reveals that while two of three scaffold architectures preserve safety within practical margins, map-reduce delegation significantly degrades measured safety. This degradation, quantified as NNH=14, means one additional safety failure for every fourteen queries processed through map-reduce, on our tested benchmark mix.
The research emphasizes that these aggregate findings mask considerable benchmark-specific heterogeneity. Universal claims about scaffold safety are not supported, necessitating per-model and per-configuration testing for accurate safety assessment.
Evaluation Format and Scaffold Degradation
A deeper measurement problem was uncovered: switching from multiple-choice (MC) to open-ended (OE) format on identical items shifts safety scores by 5-20 percentage points, a magnitude larger than any observed scaffold effect. This highlights that measured degradation reflects an instrument-deployment mismatch rather than an alignment failure.
Enterprise Process Flow
Within-format scaffold comparisons yield null effects, isolating format conversion, not scaffold architecture, as the operative variable. Map-reduce strips MC answer options during task decomposition, inadvertently converting an MC item into an open-ended one. This format-stripping, rather than true alignment failure, drives the measured degradation.
| Benchmark (Safety Property) | MC Format (Baseline Safety Rate) | OE Format (Safety Rate) | Gap (OE - MC) |
|---|---|---|---|
| Sycophancy Resistance | 33.7% | 53.3% | +19.6 pp |
| BBQ (Bias) | 83.0% | 99.2% | +16.2 pp |
| TruthfulQA | 79.3% | 85.0% | +5.7 pp |
| AI Factual Recall (Control) | 77.0% | 76.0% | -1.0 pp |
Property-Specific Heterogeneity and Sycophancy
The study reveals significant property-specific heterogeneity, where map-reduce degradation concentrates on MC-format benchmarks. The AI factual recall control, despite using the same format and scaffolds, remains robust, indicating property-specific vulnerability.
Sycophancy, with the lowest baseline safe rate (31.0% non-sycophantic), is the only property where all three scaffolds improve performance. However, it also exhibits the largest and most unpredictable model-scaffold interaction in the study, ranging from -16.8 pp (Opus 4.6) to +18.8 pp (Llama 4) under map-reduce.
Case Study: Sycophancy Model Interaction
Opus 4.6: Sycophancy resistance degrades from 49.0% to 32.2% (-16.8 pp) under map-reduce, representing the single largest scaffold-induced safety degradation observed in any model-benchmark combination in this study.
Llama 4: Sycophancy resistance improves from 11.0% to 29.8% (+18.8 pp) under map-reduce, the single largest scaffold-induced safety improvement observed.
This highlights that architectural interventions can simultaneously harm one model's sycophancy resistance while improving another's, underscoring the need for per-model, per-configuration testing.
