AREX proposes a recursively self-improving deep research agent
The paper introduces AREX, a deep research agent that uses two loops:
- an inner loop that performs research
- an outer loop that audits the answer against constraints
The key idea is to let the system iteratively improve its own outputs while checking whether the final answer still satisfies the required conditions. The post points to both the paper and the code repository.
