AREX-2 - Harness or Model: Who Should Run the Loop?

Why watch

A technical deep-dive on AREX-2, a 27B open-weights model from BAAI fine-tuned from Qwen3.8-27B, designed to autonomously run try-check-retry loops instead of relying on external harnesses. The video explores the paper's approach to self-reflection in code execution, the three-step data pipeline, and benchmarks. For developers and researchers interested in LLM agents and autonomous code execution systems.
