ReWAM addresses two deployment bottlenecks in chain-of-thought-based universal multimodal embeddings: GRPO's uniform token advantage is replaced by Retrieval-aware Self-Distillation (RASD) that builds privileged evidence-based guidance for token-level supervision, and retrieval-adaptive early stopping cuts CoT latency without hurting retrieval quality.
