BAAI released AREX-2, a 27B dense Qwen3.8-compatible multimodal agent model with 262K context, now open-weighed with GGUF builds. It learns test-time self-improvement—propose, measure, reflect, revise—trained on coding and ML tasks with verifiable feedback, and this behavior transfers to deep research without extra search trajectories.
