Think Fast: Estimating No-CoT Task-Completion Time Horizons of Frontier AI Models
Researchers measured how well frontier AI models perform complex reasoning without explicit chain-of-thought (CoT) tokens, finding that no-CoT task-completion time horizons have doubled yearly over six years. GPT-5.5 now reaches over 3 minutes of reasoning complexity, with projections suggesting frontier models could exceed 7 minutes by 2028 and 25 minutes by 2030, raising concerns about the effectiveness of current AI safety monitoring approaches.
