Smaller AI models match larger ones using hidden reasoning and memory
- A smaller model called BDH-CQ achieved 29.5% accuracy on ARC-AGI, a benchmark for general reasoning, using internal reasoning steps and temporary memory storage.
- GPT-5.6 Sol improved from 13.3% to 38.3% on the same benchmark by keeping reasoning steps and using 6 times fewer input tokens than before.
