LongVideoAgent Qwen2.5-7B

This repository hosts the released LLM checkpoint for LongVideoAgent, a multi-agent framework for long-video question answering. This model is a Qwen2.5-7B-based checkpoint used in the LongVideoAgent project.

Overview

LongVideoAgent decomposes long-video reasoning into multiple roles:

• MasterAgent for planning and answer generation
• GroundingAgent for subtitle-based temporal grounding
• VisionAgent for local visual evidence extraction

This checkpoint is intended for use with the official LongVideoAgent codebase and evaluation pipeline.

LongTVQA+ Performance

Compared with the Qwen2.5-7B-Instruct baseline, this checkpoint improves LongTVQA+ accuracy by 6.66 percentage points.

Model	LongTVQA+ Acc	Delta
Qwen2.5-7B-Instruct	57.33%	-
LongVideoAgent Qwen2.5-7B	64.00%	+6.66%

Intended Use

Use this model for:

• Research on long-video question answering
• Reproducing LongVideoAgent experiments
• Studying agentic reasoning over long videos

This checkpoint is not a general-purpose video model by itself. For inference and evaluation, please use the official repository:
