BAAI's AREX (24 authors, 124 upvotes on HF Daily Papers) alternates between gathering evidence and drafting provisional answers, then audits those answers constraint-by-constraint. The distinguishing mechanism is a learned autonomous context-update tool that compresses growing interaction history into a compact improvement state with no external critic model. 4B dense and 122B-A10B MoE variants report wins over comparable-scale baselines on BrowseComp, WideSearch, DeepSearchQA and Humanity's Last Exam. Self-improvement inside the context loop rather than via a critic is the architectural idea worth stealing.
