Tencent Releases EVIE-8B Open-Source Visual Document Retrieval Model

Tencent has open-sourced EVIE-8B, an 8.4B-parameter visual document retriever that scores 66.75 nDCG@10 on ViDoRe V3 and ranks first on that leaderboard's mean task score of 66.24.

The model uses 4096D per-token multi-vector embeddings with MaxSim late-interaction scoring and bidirectional attention, and it serves as the teacher for the lightweight EVIE-4.5B model.

Model weights, inference pipelines, and evaluation suites are available, while the formal research paper is promised for a future release.
