Quantitative Models and Construction Methods Model Name: Jet-Nemotron - **Model Construction Idea**: The model is built using an innovative post-neural architecture search method, focusing on optimizing pre-trained Transformer models[15][16] - **Model Construction Process**: - Start with a pre-trained full-attention model and inherit its multi-layer perceptron weights - Use PostNAS method to determine the optimal placement of full-attention layers by training a "one-time" super network - Evaluate various linear attention modules and select Gated DeltaNet as the base, then design the JetBlock module with dynamic causal convolution kernels - Perform hardware-aware architecture search to ensure efficiency in real hardware deployment[16][17][19] - **Model Evaluation**: The model demonstrates significant performance and efficiency improvements, setting a new benchmark for linear attention design[20][22] Model Backtest Results Jet-Nemotron - **MMLU Accuracy**: 49.6[19] - **Common Sense Reasoning Accuracy**: 62.0[19] - **Throughput Improvement**: 47 times compared to Qwen3-1.7B-Base[19] - **Cache Size Reduction**: Reduced to one forty-seventh of the original size[19] Quantitative Factors and Construction Methods Factor Name: RLCF (Reinforcement Learning from Checklist Feedback) - **Factor Construction Idea**: Use dynamically generated checklists to evaluate model responses, providing a more effective alignment method compared to traditional reward models[48][49] - **Factor Construction Process**: - Define checklist core features: each item must be a verifiable yes/no question - Generate checklists using direct and candidate methods - Sample candidate response pairs from the base policy - Score each checklist item using AI judges and verification programs - Calculate weighted average scores and filter significantly different response pairs - Train using direct preference optimization[49][51][52] - **Factor Evaluation**: The method shows stable improvement in instruction adherence across various benchmarks, particularly excelling in handling "content" constraints[51][52] Factor Backtest Results RLCF - **IFEval Improvement**: 2.8-3.0%[51] - **FollowBench Constraint Satisfaction Level**: 8.2% improvement[51] - **InFoBench Overall Requirement Adherence Rate**: 6.9% improvement[51] - **Content Constraint Hard Satisfaction Rate**: 6.4 percentage points higher than baseline[51]

Waymo目前在凤凰城、旧金山、洛杉矶、奥斯汀和亚特兰大提供付费自动驾驶出租车服务。该公司还 计划在迈阿密、华盛顿特区和达拉斯推出商业服务。 在华盛顿州，Waymo早在2022年就已经在贝尔维尤开始测试车辆。该公司在博客文章中写道："我们花 了数年时间熟悉该地区——从湖区周边的社区，到其众所周知的潮湿天气。"该公司补充称，正在努力 将自动驾驶出租车运营扩展至更广泛的西雅图都市圈。 在Waymo开始在两座城市测试其自动驾驶技术之前，这些车辆最初将由人工驾驶。据报道，该公司表 示，希望明年开始在丹佛和西雅图大都会地区提供自动驾驶出租车服务，"只要我们得到允许"。 智通财经APP获悉，Alphabet(GOOGL.US)旗下自动驾驶部门Waymo本周将在科罗拉多州丹佛市和华盛 顿州西雅图市推出自动驾驶出租车服务，为未来的商业运营奠定基础。该公司在一篇博客文章中表示， 该公司将"带着配备第五代Waymo Driver的捷豹I-PACE和配备第六代Waymo Driver的Zeekr RT混合车 队"抵达丹佛。 ...

这一裁决引发了市场强烈反应。周三盘前交易中，谷歌母公司Alphabet股价一度涨超6%，苹果股价上涨 约3%。华尔街分析师将此视为两家公司的重大胜利，因为这保护了谷歌与苹果价值200亿美元年度合作 的核心商业模式。 美国法院对谷歌反垄断案的最新裁决为苹果带来了意外胜利，法官允许谷歌继续向苹果支付超过200亿 美元的年度搜索引擎默认费用，这一决定保护了苹果最重要的服务收入来源之一。 美国地区法官Amit P. Mehta最新裁定，禁止谷歌签署排他性搜索协议，但拒绝了司法部要求强制剥离 Chrome浏览器等严厉措施。法官明确表示，谷歌可以继续为其产品的分发进行付费，禁止这些协议将 损害苹果等合作伙伴的利益。 对苹果而言，这一裁决的意义尤为重大。谷歌向苹果支付的200亿美元费用虽然仅占苹果年收入的约 5%，但对利润贡献巨大。 苹果服务业务（包括来自谷歌的许可费）在截至6月的12个月期间，每收入1美元可获得75美分的毛利 润，而苹果硬件业务同期毛利率仅为37%。 失去这一高利润收入来源对苹果来说时机糟糕。iPhone仍占苹果年收入的一半以上，但过去三年平均年 收入增长率仅为2%。分析师预计，在截至明年9月的苹果财年中 ...
