OpenAI’s new reasoning technique alarms AI safety experts
Why it matters
OpenAI is shipping a fundamentally different approach to model reasoning (recurrent depth vs. sequential chains), which changes how practitioners think about reasoning trade-offs and opens a safety debate that will reshape frontier lab roadmaps.
Key signals
- OpenAI Astra model uses 'recurrent depth' technique
- Breaks from sequential reasoning architecture
- Safety experts raising concerns about the approach

The hook
OpenAI's 'recurrent depth' breaks the mold — and alarms safety researchers. Here's why a new reasoning architecture matters.
OpenAI’s new Astra model will use “recurrent depth,” a technique that allows the model to operate outside of the sequential thinking that characterizes most reasoning models.
