Feature👀: Why Does The F-47’s Design Look So Different Than What Many Expected? Most 6th gen fighter concepts have been tailless deltas, and China is pursuing that planform, but Boeing's F-47 went a very different direction. twz.com/air/why-does-t…
这次世界杯美国的各场地，没有一个是为世界杯特建的，全是现成拿来就用。 对此，国内自媒体平台上几乎全是惊叹和正面评论。 各个同类视频下—— 最频繁出现的一句：不是说美国经济崩溃了吗？！ 最一针见血的一句：看看这三年美股涨了多少。 最五味杂陈的一句：一百年前初来美国时，李鸿章就已经自闭了。
🚨 ¡INCREÍBLE! 🇺🇸✈️ Un piloto de Ohio hizo un vuelo especial de más de 5 HORAS y dibujó en el cielo “USA 250” más el mapa completo de Estados Unidos. ¡Todo rastreado en vivo por Flightradar24! Un tributo épico al 250 aniversario de América. 🔥
The amazing BBG-1 USS Defiant: costs ten times as much as an Arleigh Burke-class destroyer (more than a Ford-class supercarrier!), but delivers about 60% more firepower. #art by Tim Samedov. artstation.com/artwork/6LrXyW
A single Starship launch will deploy 60 next-gen @Starlink V3 satellites and add 61,000 Gbps of network capacity. By comparison, a Falcon 9 carrying 27 Starlink V2 satellites adds 2,600 Gbps. In other words, one Starship launch will add as much capacity as 23 Falcon 9 launches combined. Just 10 Starship launches carrying Starlink V3 satellites will add as much network capacity as the entire Starlink network has today. Absolutely wild.
Freedom Cruise International has unveiled plans for a $16 billion floating city designed to house 80,000 people. The mile long, nuclear powered vessel would feature schools, parks, museums, a 15,000 seat stadium, and permanent residences while continuously sailing international waters.
Grok 4 好得吓人 但99%的人不知道它能干这些👇 ✅ 自动写App ✅ 深度内容生成 ✅ 高维研究助手 以下是10个堪称作弊的Grok 4使用方法🧵
看了下DeepSeek论文，做了点笔记和思考
DeepSeek降低训练成本会不会让算力需求下降？看历史就知道了，GPT4级别token价格在一年半之内降低了100~1000倍，也没有类似的担忧(如图)
AI算力通缩是必然现象，长线旋律就是十年加速六个数量级：软件/算法加速三个数量级，硬件加速三个数量级
------------------------------
先从DeepSeek R1论文本身说起
Deepseek本身并没有像chatgpt o1那样做test time scaling获得更强推理能力，属于post-training后训练范畴，看起来和chatgpt o1不是一个路子(o1是推理的时候专门扩大“思考步骤”或“搜索过程"再挑出最优，推理时耗费比o4高几个数量级)，只不过在benchmark/推理水平上达到了相同的水平
所以从推理token价格来说，deepseek和o1比降低了27倍也是合理的。
DeepSeek-R1 是在 “DeepSeek-V3-Base” 这个预训练好的模型上进行 RL强化学习，reward机制是基于规则的奖励(rule-based reward system)，而不是普遍使用的过程奖励process neural reward model或者靠纯结果outcome
规则奖励分两个部分：
• 准确性奖励（Accuracy Reward）： 对于有确定答案的问题，评估模型生成的答案是否正确。
• 格式奖励（Format Reward）： 确保模型在回答中遵循指定格式，比如说
大模型Scaling law撞墙，基本从年初PHD们吐槽到了现在大佬们公开谈论 作为半导体从业者，这集看了太多遍不能更熟悉了 芯片行业scaling law统称摩尔定律，各路媒体在十五年前就开始悲观的展望摩尔定律消亡 有一个反直觉，或者说主流媒体这几年并不报道的是，制程摩尔定律，竟然比二十年前更快了
