How enabling two settings tripled our scores on the ARC-AGI-3 benchmark
OpenAI reports that adjusting two API settings reportedly tripled GPT-5.6 scores on the ARC-AGI-3 benchmark, improving efficiency through reasoning retention and compaction features.
OpenAI has shared findings indicating that specific API configurations can drastically alter model performance on complex reasoning tasks.
The report claims that enabling settings for reasoning retention and compaction led to a threefold increase in scores on the ARC-AGI-3 benchmark.
This suggests that inference-time optimizations may be as critical as model training for achieving high-level reasoning capabilities.
Developers might prioritize these configuration strategies to maximize output quality and computational efficiency without requiring new model weights.
