    Orca Security 用 Amazon Bedrock 构建自然语言安全查询

    Orca Security 与 AWS 合作,基于 Amazon Bedrock 构建了自然语言查询智能体 Discovery AI,可将自然语言问题转换为 Sonar 查询。相比初始基线,查询成本降低 90%、输入 token 减少 93%、延迟降低 75%,目前每天处理数千次查询,响应时间 15 秒。该方案采用 RAG 与 schema 感知查询构建的九阶段流水线,并组合使用 Amazon Titan Text Embeddings 与 Cohere Rerank 3.5。

    Character.ai 破产文件披露算力支出与收入差距

    Character.ai 在破产法庭提交的文件显示,其 2024 年每月 AI 算力支出为 1380 万美元,2025 年降至每月 1000 万美元,而订阅收入峰值仅每月 280 万美元,有时不足 100 万美元,含广告在内的全部收入峰值为每月 530 万美元。CEO Colin Adams 在宣誓书中称公司始终难以盈利、运营支出高企,法律费用也促成了破产,但即便没有法律问题业务本身也难以持续。公司通过转向低成本 GPU、改用开源权重模型后训练、裁员和在应用内加入广告与内购,将亏损收窄至每月约 800 万至 900 万美元,并称平台在破产程序中继续运营。

    Epic 转向 AI 加速开发,迪士尼新游戏延期

    Epic Games 计划在一款尚未公布的迪士尼游戏中使用 AI 生成代码和美术,该项目已从原定 3 月发售窗口延期。据 Bloomberg 报道,开发团队收到 AI 优先指令,被要求更多使用 Anthropic 的 Claude 等工具,一名游戏总监在给员工的信中称不再手写代码,所有美术都将由完整 AI 工作流生成。Epic 发言人 Jake Jones 表示公司正在拥抱 AI 加速开发,CEO Tim Sweeney 称公司正进行大规模转向,让各团队用 Unreal 做更多更好的内容。该游戏据称是一款包含漫威和星球大战角色的射击游戏,属于 Epic 与迪士尼的多年合作,迪士尼曾在 2024 年向 Epic 投资 15 亿美元。

AI game development tools have been popping up from other large companies, like Meta and Google , so Epic isn’t alone here.

    AI入口大战2.0:腾讯、阿里、字节,谁是AI办公的隐形冠军?

    AI办公正接棒AI编程成为下一个高价值场景,全球市场空间或达5000亿美元以上,中国约445亿美元。腾讯Workbuddy日活超600万暂居先发,但阿里有钉钉2600万组织、字节有高价值客户和FDE驻场团队,与企业捆绑更深。Agent真正壁垒不在模型或Harness,而在用户纠错、批准等使用数据,长期胜负取决于数据资产积累。

    (1)Harness本质是一个技术套壳 首先Harness的设计思路和底层工程代码都非常成熟且通用,属于运行基础设施——日志、权限、沙箱、存档、界面等。 其次Harness外接应用生态的连接协议MCP、Skills等,也成为了开放标准。OpenAI把Codex Harness直接开源,Dots就跑在它上面;开源的OpenClaw也成了微软Autopilot和Meta Muse的灵感来源。 所以Harness本身并不构成技术壁垒,与此同时,模型还在吃掉Harness的功能。也就是很多原本靠Harness补的能力,也正在被尝试训练进模型。 a.Agent调度执行纳入大模型(适用并行任务) 典型的例子就是Kimi,自K2.5首次推出Agent Swarm,让模型自己决定拆任务、分派子Agent开始,K2.6、K3就延续这条设计思路,把越来越多的Agent协作直接训练进模型,不再靠外部Harness串行调度。 不过目前头部模型厂的主流路线还是将Agent的调度执行框架,交给Harness去做,大模型只是被训练得很会用“拆分子任务”这个工具,当真正需要时,再通过Harness的子Agent工具派
