Overview

TimeLens-8B is a video-text model from TencentARC focused on temporal grounding and video understanding. It is fine-tuned from Qwen3-VL-8B-Instruct on TimeLens datasets, making it relevant for finding when something happens, not just what appears in a sampled frame.

On Mixpeek, TimeLens helps agents retrieve the right moment from long clips before taking action, summarizing evidence, or launching a follow-up workflow.

Architecture

Qwen3-VL-8B-Instruct fine-tune for video grounding. The model card lists TimeLens-100K and TimeLens-Bench datasets and video-text-to-text support.
