## 核心内容

针对机器人操作视频缺乏任务完成标注的痛点，研究团队发布开源权重模型RoboJev-27B。该模型基于JEV-27B-VL变体，利用52,598条episode记录进行训练，专门用于根据任务指令及视频帧预测操作成败。在同型号SO-101机器人的268个保留测试集中，其平衡准确率达到95.2%，AUROC高达0.993，显著优于仅使用4帧输入的API类前沿VLM方案，为自动化数据清洗与评估提供了高精度工具。

技术架构上，RoboJev-27B采用Rank-32 LoRA适配器仅微调语言模型而冻结视觉编码器，并引入源特定KL惩罚以锚定研究数据分布。推理端采用校准双token读出机制，单次前向传播即可输出成功/失败概率。在未见过的实验室或机器人数据上AUROC仍达0.890，社区标注数据准确率为93.3%。工程效能方面，单张H100显卡中位推理耗时仅0.26秒，每千次预测成本约0.19美元，且完整开源了包含20,628条预测记录的透明评测基准。

## 英文摘要 (Abstract)

Many robot manipulation videos do not indicate whether the task was successfully completed. RoboJev-27B is an open-weight vision-language model that takes a task instruction, 10 frames of a manipulation attempt, and (if available) final frames from auxiliary cameras and predicts whether the robot accomplished the task. RoboJev-27B is a variant of JEV-27B-VL, trained with a rank-32 LoRA adapter on the language model only (keeping the vision encoder frozen) using 52,598 episode records. It also uses a source-specific KL penalty that applies only to research data, anchoring predictions closer to the original model on those sources. It uses a calibrated two-token readout that outputs success/failure probabilities in a single forward pass. On 268 held-out episodes of the same robot model (SO-101), RoboJev-27B attains 95.2% balanced accuracy and 0.993 AUROC. It also generalises to episodes collected by unseen labs/robots (AUROC = 0.890 over 459 episodes) as well as to clearly labelled community-collected episodes (accuracy = 93.3% over 135 episodes), where the base model attains an AUROC = 0.900 on the unseen-lab/robot subset with the same inputs. It takes 0.26 seconds per episode (median, serial) to infer on a single H100, which is about \0.19 per 1,000 success predictions at 2.69 per GPU-hour (not including media processing and serving costs). RoboJev-27B is released together with its inference code, along with a transparent evaluation: 20,628 predictions organized into 29 model/protocol entries are made available to facilitate browsing and to enable reproducible benchmarking of success detection. We also compare against strong API-based frontier VLMs, which take in fewer input frames (4 images from the primary camera only); note that this comparison is not strictly like-for-like because RoboJev-27B is given more frames at inference.
