    Descript Season 8:默认就能拍出好看的视频

    Descript 发布 Season 8,通过全新的 scenes 与 layouts 流程,让原始录制素材在导入时自动套用布局、统一取景和品牌样式,默认输出专业观感,且所有内容之后仍可编辑。新版本内置数十种由视频专业人士制作的 layouts,并组成配色、字体统一的 layout pack;付费账户可创建并保存自己的 layout pack。应用 layout 时会自动添加带内置动画的 Smart transition,B-roll 可通过拖拽、直接录制或从 Descript 媒体库搜索获取。

All you have to do is drop in the B-roll, which you can do by dragging-and-dropping it in, or recording it right into the scene. Or, grab some stock footage from Descript’s massive, searchable media library. You can adjust the layout however you want, and copy-paste it into other scenes if you plan to repeat that shot later in your video. And that’s all you need to do to create a

    Descript 如何用 AI 把现有视频变成理想成片

    Descript 发布新版本,升级为更强大的 AI 视频增强器,可一键修复糟糕光线、清理音频、去除填充词、平滑跳切并提升画质。新功能包括用 Regenerate 生成自然过渡消除跳切、Portrait Lighting 与 Uplighting 自动补光、Edit with AI 擦除画面杂物,以及生成 YouTube 缩略图。未来几周还将推出 Skin Smoothing、Fill with AI 和 Generate Audio。

Maybe cutting all your filler words left you with a relentless barrage of jump cuts. Maybe you stumbled over a single word in what’s otherwise a perfect take. Maybe your dog wandered into the frame, and not in a cute way. We’ve spent the past five years building toward a place where you can fix all of that, not by laboring over a timeline but by clicking features built to fix all of

    我预期 AI 会快速进步,但不会走向通用超级智能

    Interconnects 作者认为,AI 模型几年内将在分布式 GPU 工程等基础设施能力上超越人类,但不会因此发生本质变化;真正的加速来自推理算力扩展与效率优化,模型智能的有效成本可能接近指数级下降。作者预计预训练架构与数据选择研究在 2-3 年内可被自动化,并称 RL 环境质量普遍偏低但可修复。

    of low-hanging fruit is improving the general quality of RL environments. You don’t have to look far to see another new RL data company that’s crossed $100M or $1B in revenue. There are way more than I expected. The average outputs from this sector is remarkably low-quality. Countless researchers agree that lots of what they buy is frankly crap. At the same time, the leading labs see clear return on investment from buying the data. The way that many RL environments are cruddy is clearly fixable.

    OpenAI 公测 Decisions API,返回类型化答案且速度约为 Responses API 的 10 倍

    OpenAI 将 Decisions API 开放公测,该接口把文本和图像转成代码可直接分支判断的类型化答案,官方称速度约为 Responses API 的 10 倍。请求包含 model、input 和 questions 三个字段,目前仅支持 gpt-6-luna,问题类型分为 predicate、choice 和 score 三种,分别返回概率、选项概率与加权评分。输入定价为每 1M token 0.10 美元,无输出、缓存读写费用,OpenAI 未公布准确率或校准数据,建议用户用自有标注样本设定阈值。

    Wood Mackenzie:电池储能成本已低于许多数据中心使用的天然气涡轮机

    Wood Mackenzie 报告显示,在其调查的 43 个市场、每个大洲,4 小时时长电池的成本都已低于开式循环燃气轮机。该机构预测电池电力成本将继续下降,而燃气轮机发电成本未来数十年只会更贵;太阳能仍是所有调查市场中最便宜的新增电源。中东和非洲到 2035 年 4 小时电池将便宜 33%,中国的储能成本比邻国低 55%。

    《金融时报》报道称 OpenAI 向投资人展示的年化收入比此前广泛引用的 700 亿美元低 200 亿美元,原因是 OpenAI 使用净收入口径而 Anthropic 使用包含合作伙伴销售额的总收入口径;彭博社随后报道 OpenAI 预计到年底达到 700 亿美元年化收入。同期美国 Reflection 的 Beam、法国 Mistral 的 Large 4 和德国 Aleph Alpha 的 Kolibri 三款开源模型发布,均以 AI 主权为卖点对标 DeepSeek 等中国厂商,但受访投资人表示其被投企业大多并不在意开源模型的国家来源。GLM 5.3、Kimi K3、DeepSeek V4.1 等中国模型仍在 Baseten 和 Fireworks 等云平台上最受欢迎,DeepSeek 据彭博社报道接近完成由腾讯和宁德时代联合领投的 120 亿美元融资。
