+## Evaluation
+
+### MMEB-v2
+
+Results on 78 datasets from Table 1 of the [technical report](https://github.com/Tencent/WeMM-Embedding/blob/main/assets/WeMM_Embedding_tech_report.pdf). Image and video tasks use Hit@1, while visual-document tasks use NDCG@5. Higher is better.

+### MMEB-v3
+
+Results on all 190 tasks from Table 2 of the [technical report](https://github.com/Tencent/WeMM-Embedding/blob/main/assets/WeMM_Embedding_tech_report.pdf). V3-All includes the 78 MMEB-v2 tasks, 53 text tasks, 47 agent tasks, 11 audio tasks, and MCMR. Unsupported tasks are assigned a score of zero.
