Frontier Models Can Complete Tasks Without Chain-of-Thought, Raising Safety Concerns
anpaure · x · 2026-08-03
A new paper from Redwood Research and partners explores the task-completion capabilities of frontier AI models without chain-of-thought (CoT) reasoning.
The research highlights significant safety implications if models can perform complex reasoning without outputting a CoT:
- Developers and deployment monitors couldn't easily understand model motivations or catch dangerous planning.
- Models might drift further from human thought patterns as their reasoning isn't constrained by pretraining text.
- Such models would be harder to interpret and potentially more likely to scheme.
