小模型大胜利：英伟达凭合成数据与低成本策略击败GPT-5 Pro

简报：

• 英伟达的4B小模型NVARC在ARC-AGI 2公开榜上以27.64%的成绩登顶，击败了得分18.3%的GPT-5 Pro。
• 该模型完成单任务的成本仅为20美分，约为GPT-5 Pro（超过7美元）成本的1/36。
• NVARC的获胜策略是零预训练深度学习方法，通过离线生成大规模高质量的合成数据来训练基于Qwen3-4B的小模型。
• 关键技术为“测试时微调”（TTFT），即在评估阶段针对每个新问题都使用LoRA技术进行快速微调，以适应新规则。

Small Model, Big Win: NVIDIA Defeats GPT-5 Pro with Synthetic Data and Low-Cost Strategy

Brief:

• NVIDIA's 4B small model, NVARC, has topped the ARC-AGI 2 public leaderboard with a score of 27.64%, surpassing GPT-5 Pro which scored 18.3%. 🚀
• The cost to complete a single task with NVARC is only 20 cents, approximately 1/36th the cost of GPT-5 Pro (which exceeds $7). 💰
• NVARC's winning strategy employed a zero-pre-training deep learning method, training a small model based on Qwen3-4B using large-scale, high-quality synthetic data generated offline.
• A key technique was "Test-Time Fine-Tuning" (TTFT), which involves rapid fine-tuning using LoRA technology for each new problem during the evaluation phase to adapt to new rules. 🧠

特斯拉机器人摔倒，"摘头显"动作暴露远程操控

简报：

• 在特斯拉迈阿密的一场演示活动中，其Optimus人形机器人在分发瓶装水时失去平衡向后摔倒。
• 在摔倒前，机器人双手抬至面部，做出了一个类似摘下VR头显的动作，但其头部并未佩戴任何设备。
• 该动作被外界解读为，机器人是在模仿远程操控员摘下VR头显的慌乱动作，从而暴露了其并非自主运行，而是依赖人类远程操控。
• 此事件引发了对其自主性的质疑，因为特斯拉CEO马斯克此前曾强调Optimus的演示是“完全由AI驱动，非远程操控”。

Tesla Bot Falls, 'VR Headset Removal' Gesture Exposes Remote Control

Brief:

• During a Tesla demonstration event in Miami, its Optimus humanoid robot lost balance and fell backward while distributing bottled water. 🤖💥
• Before falling, the robot raised its hands to its face, performing a gesture akin to taking off a VR headset, despite not wearing any device on its head.
• This action has been interpreted by observers as the robot mimicking the panicked movement of a remote operator removing a VR headset, thus revealing that it was not operating autonomously but relying on human remote control. 👀
• The incident has sparked questions about Optimus's autonomy, especially since Tesla CEO Elon Musk had previously emphasized that its demonstrations were "fully AI-driven, not remote-controlled." 😮
