A new preregistered study published on arXiv investigates the effectiveness of AI model evaluation harnesses, particularly focusing on visibility, baseline adequacy, and defects. The research utilized models ranging from 1.7B to 8B parameters, including Qwen3-14B, across benchmarks like LongevityBench, MMLU-Pro, and GSM8K. Findings indicate that disabling certain 'thinking' mechanisms in models can improve accuracy by allowing parsers to process previously unreadable answers, and that for smaller models, this approach is comparable to rescue configurations or GEPA-selected harnesses.
