learning. We address the unique challenges of long video reasoning by integrating three critical components: (1) a large-scale dataset, LongVideo-Reason, comprising 104K long video QA pairs with high-quality reasoning annotations across diverse domains such as sports, games, and vlogs; (2) a two-stage training pipeline that extends VLMs with chain-of-thought supervised fine-tuning (CoT-SFT) and reinforcement learning (RL); and (3) a training infrastructure for long video RL, named Multi-modal Reinforcement Sequence Parallelism (MR-SP), which incorporates sequence parallelism and a vLLM-based engine tailored for long video, using cached video embeddings for efficient rollout and prefilling. In our experiments, LongVILA-R1-7B achieves strong performance on video benchmarks, reaching 65.1% and 71.1% accuracy on VideoMME without and with subtitles, respectively, and consistently outperforming LongVILA-7B across multiple benchmarks. Moreover, LongVILA-R1-7B supports processing up to 8,192 video frames per video, and configurable FPS settings. Notably, our MR-SP system achieves up to 2.1x speedup on long video RL training. In addition, we release our training system for public availability that supports RL training on various modalities (video, text, and audio), various models (VILA and Qwen series), and even image and video generation models. On a single A100 node (8 GPUs), it supports RL training on hour-long videos (e.g., 3,600 frames).\n\n\u003Cp align=\"center\" width=\"100%\">\n\u003Cimg src=\"https:\u002F\u002Foss.gittoolsai.com\u002Fimages\u002FNVlabs_Long-RL_readme_735f2c96bd32.png\" alt=\"Stanford-Alpaca\" style=\"width: 100%; min-width: 300px; display: block; margin: auto;\">\n\u003C\u002Fp>\n\n| Models             | VideoMME (w\u002Fo sub) | VideoMME (w sub) | ActivityNet-QA (test) | LongVideoBench (val) | PerceptionTest (val) | NExT-QA (mc) | VNBench (val) |\n|:-------------------|:------------------:|:----------------:|:---------------------:|:--------------------:|:--------------------:|:--------:|:-------------:|\n| **LongVILA-7B**    |      **60.1**      |     **65.1**     |       **59.5**        |       **57.1**       |       **58.1**       | **80.7** |   **63.0**    |\n| **LongVILA-R1-7B** |      **65.1**      |     **71.1**     |       **64.8**        |       **58.0**       |       **68.9**       | **81.5** |   **75.5**    |\n\n## TABLE OF CONTENTS\n1.

Please do the following steps if you neet it.\n  - Set `--worker.rollout.open_ended_reward=True` in the training script.\n  - Export your openai API with `export OPENAI_API_KEY=xxx`.\n- [x] **Cached video embeddings**:\n- We support using cached video embeddings for video RL training. Because video encoding during training is slow for large batch & long video frames. Please do the following steps if you neet it.\n  - Follow `verl\u002Futils\u002Fcache_video_embeds_vila.py` to cache video embeddings in a local directory.\n  - Set `--data.cache_dir` and `--worker.actor.cached_embeds_dir` in the training script.\n- [x] **Chunked gathering**:\n- We support chunked gathering for `all_gather_data_proto`. Because it might suffer from CPU OOM if you machine do not have enough CPU memory, and also large batches or long video frames are needed. Please do the following step if you neet it.\n  - Set `--worker.rollout.num_chunk_seq` in the training script. It can be 8\u002F16\u002F32. Larger ones cost less memory, but more time.\n\n## Installation\n\n```bash\ngit clone https:\u002F\u002Fgithub.com\u002FNVlabs\u002FLong-RL.git\ncd Long-RL\npip install -e .\n```\nIf you want to train Qwen-Omni models, please\n```bash\nbash vllm_replace.sh\n```\n\n## Training\n### Single node\nFor single node (within 8 GPUs), you can refer to the training scripts in the `examples` directory. For example,\n```bash\nbash examples\u002Fnew_supports\u002Fqwen2_5_vl_3b_video_grpo.sh $VIDEO_PATH\n```\n\n### Multi-nodes\nFor jobs that requires multi-nodes, you can refer to the ways mentioned in the EasyR1 repo, [here](https:\u002F\u002Fgithub.com\u002Fhiyouga\u002FEasyR1\u002Ftree\u002Fmain?tab=readme-ov-file#how-to-run-70b-model-in-multi-node-environment).\n\nWe provide additional examples for `sbatch` scripts like, where `TRAIN_SCRIPT` is the script to train on single node, `NNODES` is the number of nodes required.\n```bash\nbash scripts\u002Fsrun_multi_nodes.sh $TRAIN_SCRIPT $NNODES\n```\n\nFor example, \n```bash\nbash scripts\u002Fsrun_multi_nodes.sh examples\u002Fnew_supports\u002Fqwen2_5_vl_3b_video_grpo.sh 2\n```\n\n### Merge Checkpoint in Hugging Face Format\nThis follows the ways in the EasyR1 repo.\n```bash\npython3 scripts\u002Fmodel_merger.py --local_dir checkpoints\u002Feasy_r1\u002Fexp_name\u002Fglobal_step_1\u002Factor\n```\n\n## LongVideo-Reason\nWe provide detailed instructions on the data generation process and how to evaluate models on our `LongVideo-Reason` benchmark in the [`longvideo-reason`](longvideo-reason\u002F) directory. \n\n## Examples\n\u003Cdiv align=\"center\">\n\u003Ca href=\"https:\u002F\u002Fdrive.google.com\u002Ffile\u002Fd\u002F1QJ-ZsDrmYS8v1XU4eWfYu5oHuXeyGSdK\u002Fview?usp=share_link\">Football Video\u003C\u002Fa>\n\u003C\u002Fdiv>\n\u003Cp align=\"center\" width=\"100%\">\n\u003Cimg src=\"https:\u002F\u002Foss.gittoolsai.com\u002Fimages\u002FNVlabs_Long-RL_readme_1f7c06b18c08.png\" alt=\"Stanford-Alpaca\" style=\"width: 100%;

Because it might suffer from CPU OOM if you machine do not have enough CPU memory, and also large batches or long video frames are needed. Please do the following step if you neet it.\n  - Set `--worker.rollout.num_chunk_seq` in the training script. It can be 8\u002F16\u002F32. Larger ones cost less memory, but more time.\n\n## Installation\n\n```bash\ngit clone https:\u002F\u002Fgithub.com\u002FNVlabs\u002FLong-RL.git\ncd Long-RL\npip install -e .\n```\nIf you want to train Qwen-Omni models, please\n```bash\nbash vllm_replace.sh\n```\n\n## Training\n### Single node\nFor single node (within 8 GPUs), you can refer to the training scripts in the `examples` directory.

支持对开放式问答（非多选题问答）进行训练。如果需要，请执行以下步骤。\n  - 在训练脚本中设置 `--worker.rollout.open_ended_reward=True`。\n  - 使用 `export OPENAI_API_KEY=xxx` 导出你的 OpenAI API（OpenAI 应用程序接口）。\n- [x] **缓存的视频嵌入（Cached video embeddings）**：\n  - 支持使用缓存的视频嵌入进行视频 RL（Reinforcement Learning，强化学习）训练。因为对于大批量（batch）和长视频帧，视频编码在训练时很慢。如果需要，请执行以下步骤。\n  - 参考 `verl\u002Futils\u002Fcache_video_embeds_vila.py` 将视频嵌入缓存到本地目录。\n  - 在训练脚本中设置 `--data.cache_dir` 和 `--worker.actor.cached_embeds_dir`。\n- [x] **分块收集（Chunked gathering）**：\n  - 支持对 `all_gather_data_proto` 进行分块收集。因为如果你的机器没有足够的 CPU（Central Processing Unit，中央处理器）内存，可能会导致 CPU OOM（Out of Memory，内存溢出），而且需要大批量（batch）或长视频帧。如果需要，请执行以下步骤。\n  - 在训练脚本中设置 `--worker.rollout.num_chunk_seq`。可以是 8\u002F16\u002F32。数值越大，内存消耗越少，但耗时越长。\n\n## 安装\n\n```bash\ngit clone https:\u002F\u002Fgithub.com\u002FNVlabs\u002FLong-RL.git\ncd Long-RL\npip install -e .\n```\n\n如果想训练 Qwen-Omni 模型，请执行\n\n```bash\nbash vllm_replace.sh\n```\n\n## 训练\n\n### 单节点（Single node）\n\n对于单节点（8 GPU 以内），你可以参考 `examples` 目录中的训练脚本。例如，\n\n```bash\nbash examples\u002Fnew_supports\u002Fqwen2_5_vl_3b_video_grpo.sh $VIDEO_PATH\n```\n\n### 多节点（Multi-nodes）\n\n对于需要多节点的任务，请参考 EasyR1 仓库中提到的方法，[点击这里](https:\u002F\u002Fgithub.com\u002Fhiyouga\u002FEasyR1\u002Ftree\u002Fmain?tab=readme-ov-file#how-to-run-70b-model-in-multi-node-environment)。\n\n我们还提供了 `sbatch` 脚本的额外示例，其中 `TRAIN_SCRIPT` 是单节点训练脚本，`NNODES` 是所需的节点数量。\n\n```bash\nbash scripts\u002Fsrun_multi_nodes.sh $TRAIN_SCRIPT $NNODES\n```\n\n例如，\n\n```bash\nbash scripts\u002Fsrun_multi_nodes.sh examples\u002Fnew_supports\u002Fqwen2_5_vl_3b_video_grpo.sh 2\n```\n\n### 合并为 Hugging Face 格式的 Checkpoint（模型检查点）\n\n遵循 EasyR1 仓库的方法。\n\n```bash\npython3 scripts\u002Fmodel_merger.py --local_dir checkpoints\u002Feasy_r1\u002Fexp_name\u002Fglobal_step_1\u002Factor\n```\n\n## LongVideo-Reason\n\n我们在 [`longvideo-reason`](longvideo-reason\u002F) 目录中提供了数据生成过程的详细说明，以及如何在我们的 `LongVideo-Reason`

GPU）\n- **Python**：3.10+\n- **CUDA**：11.8+\n\n### 前置依赖\n\n```bash\n# 创建虚拟环境（推荐）\nconda create -n long-rl python=3.10\nconda activate long-rl\n\n# 安装 PyTorch（根据 CUDA 版本选择）\npip install torch==2.1.0 --index-url https:\u002F\u002Fdownload.pytorch.org\u002Fwhl\u002Fcu118\n```\n\n## 安装步骤\n\n```bash\n# 克隆仓库\ngit clone https:\u002F\u002Fgithub.com\u002FNVlabs\u002FLong-RL.git\ncd Long-RL\n\n# 安装项目及依赖\npip install -e .\n```\n\n> **国内加速**：如遇网络问题，可使用国内镜像：\n> ```bash\n> git clone https:\u002F\u002Fgitee.com\u002F nvlab\u002FLong-RL.git\n> ```\n\n## 基本使用\n\n### 模型推理（最简示例）\n\n```python\nfrom transformers import AutoModel\n\nmodel_path = \"Efficient-Large-Model\u002FLongVILA-R1-7B\"\nmodel = AutoModel.from_pretrained(model_path, trust_remote_code=True, device_map=\"auto\")\n\n# 切换思考模式\nuse_thinking = True\nsystem_prompt_thinking = \"You are a helpful assistant. The user asks a question, and then you solves it.\\n\\nPlease first think deeply about the question based on the given video, and then provide the final answer.

  prompt = system_prompt_thinking.format(question=prompt)\n\nresponse = model.generate_content([prompt, {\"path\": video_path}])\nprint(\"Response: \", response)\n```\n\n### 配置视频帧数\n\n```python\n# 方式1：设置 FPS（自动计算帧数）\nmodel.config.fps = 8.0\n\n# 方式2：手动指定帧数（禁用 FPS 控制）\nmodel.config.num_video_frames, model.config.fps = 512, 0\n```\n\n### 使用 vLLM 引擎加速推理\n\n```bash\n# 先准备远程代码\nmkdir remote_code\ncp path_to\u002FEfficient-Large-Model\u002FLongVILA-R1-7B\u002F*.py remote_code\n```\n\n然后使用 vLLM 进行推理（需安装 `vllm==0.9.1`）。\n\n## 训练示例\n\n项目提供了多种训练脚本，位于 `examples\u002Fnew_supports\u002F` 目录：\n\n| 场景 | 脚本 |\n|------|------|\n| 长视频 RL 训练 | `qwen2_5_vl_3b_video_1h.sh` |\n| VILA 视频训练 | `longvila_7b_video_grpo.sh` |\n| 图像生成 RL | `sd3_image_grpo.sh` |\n| 视频生成 RL | `wan_video_grpo.sh` |\n\n运行训练：\n```bash\nbash examples\u002Fnew_supports\u002Flongvila_7b_video_grpo.sh\n```\n\n## 核心特性\n\n- **长视频支持**：最多处理 8,192 帧\u002F视频\n- **多模态 RL**：支持视频、文本、音频、图像生成\n- **高效训练**：单节点 A100 支持小时级视频训练（3,600 帧）\n- **多种算法**：支持 GRPO、DAPO、Reinforce","某教育科技公司研发团队致力于开发一款能深度解析小时级网课视频的智能助教，需实现对课程内容的逻辑推理与精准问答。\n\n### 没有 Long-RL 时\n- 现有模型显存限制严重，无法一次性输入整节课视频，必须频繁切片导致上下文断裂。\n- 模型仅能识别画面物体，缺乏跨时间段的逻辑推理能力，无法回答“前后知识点关联”类问题。\n- 长视频强化学习训练极其缓慢，单节点训练数天才能收敛，严重拖慢产品上线进度。\n- 缺乏专用长视频推理数据，模型回答常出现事实性幻觉，准确率徘徊在 60% 左右。\n\n### 使用 Long-RL 后\n- Long-RL 支持单节点处理 8,192 帧视频，完整覆盖 1 小时课程，无需切片即可保持全局上下文。\n- 结合思维链监督微调与强化学习，模型具备逐步推理能力，VideoMME 基准准确率提升至 71.1%。\n- 采用 MR-SP 并行训练架构，长视频 RL 训练速度提升 2.1 倍，大幅降低算力成本与迭代周期。\n- 基于 104K 高质量长视频推理数据集优化，显著减少幻觉，在多模态基准测试中全面超越基线模型。\n\nLong-RL 通过高效的多模态序列并行技术与强化学习框架，真正实现了长视频智能推理的低成本规模化落地。","https:\u002F\u002Foss.gittoolsai.com\u002Fimages\u002FNVlabs_Long-RL_dcd0ff00.png","NVlabs","NVIDIA Research
