    Parcae:用稳定循环模型以更少参数实现更高性能

    Together AI 发布稳定循环语言模型架构 Parcae,通过反复使用相同层来增加计算量,而不扩大参数规模。实验中,Parcae 的验证困惑度较参数和数据匹配的 RDM 最多降低 6.3%,770M 模型的下游表现接近参数量两倍的 Transformer;训练代码和模型已发布。

    to scale quality by increasing recurrence rather than purely scaling data, opening up an efficient frontier for training memory-constrained on-device models. Traditional scaling laws tell us that to achieve the best performance, we need to scale FLOPs, often with more parameters or data. But as models move to the edge and inference costs skyrocket, we wonder: Can we scale quality without inflating memory footprint? To that end, we’ve been exploring looped architectures, models that increase com

    Sam Altman 遭燃烧瓶袭击后反思 AI 权力、治理与 OpenAI 十年

    Sam Altman 称其住所凌晨遭人投掷燃烧瓶,所幸无人受伤,并借此回应近期针对他的舆论及个人争议。他主张 AI 应广泛赋能个人,不能由少数实验室集中控制,同时需要全社会共同应对安全威胁和经济转型。他还回顾了 OpenAI 创立十年来的成绩与失误,并强调民主程序应比企业拥有更大的权力。

    s ways to do this are individual empowerment and making sure democratic system stays in control. It is important that the democratic process remains more powerful than companies. Laws and norms are going to change, but we have to work within the democratic process, even though it will be messy and slower than we’d like. We want to be a voice and a stakeholder, but not to have all the power. A lot of the criticism of our industry comes from sincere concern about the incredibly high stakes of this

    Google Research 发布 ConvApparel:量化并弥合用户模拟器的真实感差距

    Google Research 推出 ConvApparel,一个包含 4000 多段人机多轮对话(近 15000 轮)的服装购物领域数据集,用于量化 LLM 用户模拟器的“真实感差距”。该数据集采用双智能体采集协议,将用户随机分配给有帮助的“Good”智能体或故意不配合的“Bad”智能体,并配有逐轮满意度、挫败感等标注。研究还提出反事实验证方法,测试模拟器面对训练分布外行为时能否合理反应。

    ors, we need to quantify it. In our recent paper , we introduce ConvApparel , a new dataset of human-AI conversations designed to do exactly that. ConvApparel exposes the hidden flaws in today’s user simulation and provides a path towards building AI-based testers we can trust.

    系统 AI:使用大语言模型优化数据库查询执行

    Together AI 联合多家机构推出 DBPlanBench,让 GPT-5 通过 JSON Patch 定向改写 Apache DataFusion 查询执行计划,无需修改数据库引擎。TPC-H 和 TPC-DS 生成负载的中位加速约为 1.1x–1.2x,最高达 4.78x,样本中 60.8% 的查询性能提升超过 5%;相关工具与代码已开源。

    nBench thereby converts the optimization task from a statistical computation into a semantic reasoning problem, in which the LLM analyzes the plan's topology to identify logical flaws in join ordering. To implement these fixes safely, we instruct the LLM to avoid regenerating an entire physical plan from scratch; instead, it applies targeted edits to DataFusion’s existing physical plan, reducing the risk of syntax errors or invalid plan topology. Concretely, the LLM generates JSON Patches (RFC 6

    合同能冻结自主武器相关法律吗?——解析 OpenAI 与国防部协议
