    Cohere 发布 Embed 5 系列嵌入模型,Pro 与 Fast 共享同一嵌入空间

    Cohere 发布 Embed 5 系列嵌入模型,包含面向最高质量的 Embed 5 Pro 和面向延迟与成本敏感场景的 Embed 5 Fast,两者共享同一嵌入空间,可用 Pro 建索引后用任一模型查询而无需重建索引。Embed 5 支持多模态输入与检索、100 多种语言和 128K token 上下文窗口,Pro 在 ViDoRe V3 上平均得分 85.8,Fast 为 84.5。模型已在 Cohere API、Model Vault、Microsoft Foundry 和 Amazon SageMaker 上线,Pro 定价为每百万 token 0.12 美元,Fast 为 0.08 美元。

    ned pages, slide decks, schematics, and charts contain information that text extraction may miss. Embed 5 can embed page images directly (page-image), or combine an image with its metadata into a single vector (fused text-image). On fused text-image corpora, Embed 5 Pro averages 82.3 across five datasets, ahead of Embed 5 Fast at 81.2 and Gemini Embedding 2 at 61.3. Pro outperforms Gemini Embedding 2 on every dataset in the suite. Page image retrieval is also robust: Embed 5 Pro continues to lea

    9 月 1 日宣布恢复独立运营的 Manus 发布回归后首个大版本更新 Manus 2.0,桌面端升级为 Manus Studio,新增视频时间线编辑与 Game Dev 游戏开发能力,并推出个人 Agent 应用 Cue。Cue 为每个 Agent 配备独立邮箱、电话号码、钱包和电脑,可对外发消息、在预算内付款、代接电话并留下通话摘要,多个 Agent 还能拉进同一群聊分工协作,目前处于凭邀请码的抢先体验阶段。新一代自研 Agent 框架 Cascade 按需引入专业能力,官方测试中相比此前系统 Token 消耗减少 23.2%、任务完成时间缩短 28.2%、运行成本降低 32%。Manus 同时透露面向国内市场的产品正在筹备,团队正在组建。

    真是……真是绕了好大一圈啊。 刚刚,9月1日才宣布恢复独立运营的Manus,发布了回归后的首个大版本更新—— Manus 2.0 。 是的,没有改名,还叫Manus,只不过是 2.0 。 新的Agent底座、新的创作工作台,还有一款全新的个人Agent应用,一口气都来了。 从被Meta收购,到拆分、恢复独立,这个曾经把通用Agent带到聚光灯下的名字,如今重新带着一整套产品出场。 其中,桌面端升级成了Manus Studio,能剪视频、做游戏,人还可以随时接手修改; 新应用Cue则给Agent配上邮箱、电话号码、钱包和电脑,几个助手还能拉进一个群里办事。 虽然这次面向海外用户发布,但Manus同时透露,面向国内市场的产品也正在筹备,团队正在组建。 除开发布本身以外,Manus 2.0的发布时间节点也颇有意思。 就在“老东家”Meta的个人Agent Muse登顶美国App Store免费榜10天后,恢复独立的Manus带着2.0和Cue回来了。 曾经的收购方和被收购方,如今在Agent赛道上成了对手。 蝴蝶飞过沧海,继续翻山越岭~ 先说这次的新应用,个人Agent, Cue 。 Cue

    Sam Altman 称 OpenAI 在模型安全达标前不会上市

    Sam Altman 在 DevDay 主题演讲后的记者问答中表示,OpenAI 不会在能够对模型安全作出可靠承诺之前上市,且没有给出明确时间表。他称等待过久对世界不利,但当前正处在模型能力跃升与新的安全要求阶段,此时推进 IPO 并不明智。他还提到,上市可能带来为安全而让华尔街支持者失望的压力。

    ay主题演讲后与记者的问答环节中说道。与此同时,他表示,等待太久才进行IPO会“对世界不利”。 奥尔特曼的这番言论出台之际,围绕OpenAI及其竞争对手能否控制自身所创造之物的争议已持续数月。今年7月,有消息曝出,OpenAI一个未发布的模型在OpenAI不知情的情况下入侵了竞争对手AI实验室Hugging Face。随后,OpenAI、Anthropic、Meta和谷歌又接连曝出更多网络安全事件。Anthropic一名员工高调辞职的信件引发了公众讨论:这些系统对整个社会的风险究竟有多大。OpenAI与其竞争对手一道呼吁监管并“控制前沿发展的节奏”。而本月早些时候,奥尔特曼在一次采访中表示,公司今年很可能不会上市。 在DevDay上,奥尔特曼对“控制前沿发展的节奏”究竟意味着什么言辞谨慎,不愿将其称为彻底的放缓。“对我们来说,控制节奏意味着我们把安全和对齐置于能力之前,”奥尔特曼说。但他表示担忧,上市可能会带来一种可能,即“以安全或其他什么名义让华尔街的支持者失望”,而且在“向能力极强的模型转型、并面临一种新的安全要求”之际这样做似乎并不明智。他说,OpenAI将优先考虑安全,以便“自

    Shopify 为何放弃 React Native 转向原生开发
