We introduce Vidi, a family of Large Multimodal Models (LMMs) for a wide range of video understanding and editing (VUE) scenarios. The first release focuses on temporal retrieval (TR), i.e., identifying the time ranges in input videos corresponding to a given text query.

This model is the first release for temporal retrieval.

Please find the inference and evaluation code on https://github.com/bytedance/vidi.
