Ant Group's first guardrail model family (0.8B/2B/4B/8B): policy-adaptive multimodal guard models that treat the active safety policy as a runtime input rather than baking policies into weights, with fast/slow dynamic reasoning. Built on Qwen3-VL, Apache-2.0. Ant's analogue to Qwen3Guard; early traction is modest.
