    Browser Use 在 WebVoyager 基准上取得 89.1% 成功率

    Browser Use 在 WebVoyager 基准的 586 个网页任务上取得 89.1% 成功率,并称达到当前最优水平,且完全开源。评测基于 gpt4o,作者对原代码的提示词做了调整并迁移到 Langchain,同时移除了 55 个无法完成或数据过期的任务。作者也指出该数据集主要考察智能体规划能力,并未覆盖 iFrame、Shadow 元素等复杂站点理解场景。

We're not stopping here! Coming soon: make manually labeled items more transparent; add proxy rotations for Cloudflare blocking; test all kinds of models and different setups (Claude, GPT-4o, Llama 3, etc.); test different setups (single vs multiple images, single vs multiple tasks, etc

    Anthropic 发布 Clio:隐私保护下的 AI 使用分析工具

    Anthropic 发布自动化分析工具 Clio,可在保护用户隐私的前提下分析 claude.ai 的真实使用情况。Clio 由 Claude 完成对话特征提取、语义聚类、簇描述和层级构建,数据自动匿名化聚合,仅高层聚类对分析人员可见。对 100 万条对话的分析显示,Web 与移动应用开发类对话占比超过 10%,教学学习类超过 7%,商业策略与运营类接近 6%。Clio 还帮助识别了用相似提示词结构批量生成 SEO 垃圾内容的自动化账号网络,并发现翻译类有害内容等被原有安全分类器漏报的情况。

Some of these were perhaps surprising, including: “Hints” for crossword puzzles; Dungeons & Dragons gaming; Counting the r’s in the word “strawberry”. Claude usage varies by language Claude usage varies considerably across languages, reflecting varying cultural contexts and needs. We calculated a base rate of how often each language appeared in conversations overall, and from there we could identify topics whe

    Lilian Weng 长文梳理强化学习中的奖励劫持

    Lilian Weng 在 Lil'Log 发布长文,系统梳理强化学习中的奖励劫持问题,即智能体利用奖励函数的缺陷或歧义获取高分却未真正完成任务。文章按 RL 任务、LLM 任务和现实生活分类列举实例,并讨论 RLHF 中代理奖励与真实奖励的差距、LLM 作为评估者的位置偏差,以及对抗奖励函数、解耦审批、异常检测等缓解思路。作者指出,随着模型能力增强,奖励劫持更易出现,而针对 RLHF 和 LLM 的实用缓解研究仍然有限。

    Zyphra 发布 5 万亿 token 数据集 Zyda-2,用 NVIDIA NeMo Curator 将处理时间从 3 周缩短到 2 天

    Zyphra 发布 Zyda-2,一个约 5 万亿 token 的宽松许可数据集,由 DCLM、FineWeb-Edu、Zyda-1 和 Dolma v1.7 的 Common Crawl 部分经跨数据集去重与模型过滤组合而成,已在 HuggingFace 上开放。借助 NVIDIA NeMo Curator 的 GPU 加速,数据处理从 CPU 上的 3 周缩短到 2 天,总拥有成本降低 2 倍。Zyphra 称用 Zyda-2 退火训练的模型在 MMLU、Hellaswag 等聚合评测上优于 DCLM 和 FineWeb-Edu,其 Zamba2 系列模型即基于该数据集的早期版本训练。

    Zyphra is excited to release Zyda2, a 5-trillion token dataset composed of filtered and cross-deduplicated DCLM, FineWeb-Edu, Zyda-1, and Dolma v1.7's Common Crawl portion. Leveraging NVIDIA NeMo Curator, we've dramatically accelerated data processing from 3 weeks to 2 days while reducing costs. Zyda-2 powers our Zamba2 series, pushing the boundaries of small-LLM performance and reinforcing Zyphra's position at the forefront of efficient, high-performance language model development. At Zyphra, o

    Cartesia 发布 Based 架构:线性注意力模型平衡召回与吞吐量

    Cartesia 团队发布 Based 架构,通过结合滑动窗口注意力和线性注意力,在召回密集型任务上超越 Mamba 等次二次方模型,同时实现比 FlashAttention-2 高 24 倍的文本生成吞吐量。该架构使用二阶泰勒近似作为特征映射,并提供了 IO 感知的 CUDA 实现,代码和检查点已在 GitHub 和 Hugging Face 公开。

For instance, it would be nice if our primitives could leverage GPU Tensor Cores, specialized hardware on modern GPUs that can perform matrix multiplications (GEMMs) 16x faster for 16x16 matrices than the default (CUDA cores)! In our ICLR paper, we did a deep dive on why any model with a convolutional view (e.g. H3 or Hyena) will struggle on recall. Next, we considered two of

    FutureHouse 发布 WikiCrow:自动为 15616 个人类蛋白编码基因生成维基式条目

    FutureHouse 发布 WikiCrow,一个基于其 PaperQA 智能体平台的自动合成系统,可为技术主题生成带引用的维基百科式摘要。团队用它为 15616 个尚无条目或仅有残篇的人类蛋白编码基因生成草稿,每篇约 8 分钟,50 个实例并行,几天内完成,估计人工需约 60000 小时。评测显示 WikiCrow 约 9% 的陈述不正确,但引用来源的一致性明显优于人类编辑;PaperQA 在 PubMedQA Blind、MedQA-USMLE 及自建 LitQA 基准上优于 GPT-4、Perplexity 等系统。
