# VideoRLVR

VideoRLVR is a reinforcement learning (RL) recipe for training video reasoning models with verifiable rewards. This model is a reinforcement-learning optimized version of [Wan2.2-TI2V-5B](https://huggingface.co/Wan-AI/Wan2.2-TI2V-5B), presented in the paper [Video Models Can Reason with Verifiable Rewards](https://huggingface.co/papers/2605.15458).

The model uses an SDE-GRPO optimization backbone and rule-based feedback to improve visual reasoning in complex, procedurally generated tasks such as Maze, FlowFree, and Sokoban.

## Method Overview

VideoRLVR formulates video reasoning as the generation of verifiable visual trajectories. Key components include:
1. **SDE-GRPO**: An optimization backbone for video diffusion models.
2. **Dense Decomposed Rewards**: Verifiable, rule-based feedback to guide the model.
3. **Early-Step Focus**: A strategy that restricts policy optimization to the early denoising phase, significantly reducing training latency while preserving performance.
