7 月 31 日消息，华为今日官宣，开源盘古 5050 亿参数的 openPangu-2.0-Pro 模型（模型权重、基础推理代码）及技术报告正式开源上线。

大模型这条线，会发明哪些新名词？

@grok 部署Kimi K3最低硬件配置和成本估算

[Lucky J @_luckyj888]

Kimi K3发布后，老板让我算算本地化部署要多少钱。算完他沉默了。

K3有2.8万亿参数，MoE架构，想本地跑？最少64张H200起步。

我列了个清单：

🖥️ 显卡：64张H200，141GB显存版本
🔗 网络：NVLink交换机 + 800G光模块 + RDMA交换机
💻 CPU：双路Xeon/EPYC，PCIe 5.0
🧠 内存：每台1-2TB DDR5
💾 存储：RAID阵列，每台不低于8TB企业级SSD
❄️ 散热：液冷，风冷根本压不住
⚡ 电源：单机柜160kW，钛金电源

硬件成本：3000万（一次性）

然后我算了算电费：
64张H200，单卡0.7kW，总功耗44.8kW
加上PUE 1.55，实际取电69.44kW
工业用电1.5元/度，一小时104块
一年8760小时满载：91万

就这还没算场地、机房改造、运维人员。

老板看完账单，脸从白变红变紫变黑，沉默半天说：「小X啊，这个事儿公司需要开会讨论一下，你把材料留下先回去吧。」

走出办公室时我看他手有点抖。

三千万只是起步。本地化部署大模型，从来都不是小老板的游戏。

For my first post, I’m sharing a letter @NVIDIA signed on why open models matter.

AI will transform every industry, power every company, and be built by every country.

Open models strengthen safety and cybersecurity, accelerate innovation and diffusion, and enable sovereignty.

The world needs both frontier closed models and frontier open models.

Opus 5 泄漏：将于周四发布

- Anthropic 计划于周四推出（如果没有延误）。
- 基准性能将与 Fable 5 相当，但不会超越它。
- Anthropic 对 GPT-5.6、Kimi K3 等模型的回应

DMIT 还有少量洛杉矶现货，$10.9 一个月，包年更划算，以前是$9.9，预计后续还会涨价

CAD 领域还需要加大投入

[Brian Ratliff @BrierRat]

We got there with the Claude CAD!

Drawing interpretation is still a bit challenge. Lots of issues with drawing-to-feature misinterpretation in the little details. Claude has been quick in deciding that the drawing has mistakes. The bottom view was the zero shot initial interpretation.

I've spent some time this week modifying the semantic and episodic knowledge base of the Claude CAD system. The original was kind of an ad-hoc amalgam of skills and lessons learned. Now we have better separation as we build more. This is the 32nd build with Claude CAD and it's still getting better.

《经济参考报》委托专业检测机构对市场上部分品牌婴幼儿纸尿裤开展抽样检测，结果在“好奇”“碧芭宝贝”“Babycare”等多个品牌的婴幼儿纸尿裤中，检出毒性物质——甲酰胺。医学检测机构也在部分婴幼儿血液、尿液中检出该物质。《经济参考报》记者穿戴一款婴儿纸尿裤一夜后，血液中甲酰胺浓度也飙升近一倍。

Lots of misinformation being spread about me the last couple days, so some quick facts
- My name is Tina, not Guo Can (or Jessie Anderson). I’m one of many Raptor flight operators on console since flight2. Before that, I wrote control software for the vehicle, and was a stage software operator for flight1

- Been living in Starbase since surborbital days in 2020, absolutely love it down here. The people are wonderful and so so excited about the mission - the lows are lows but the highs are very high. My friends here are the best in the world, and I love them to the moon/mars and back :)

- The reason I decided to say something was because facts matter, but also because wanted to share my real life journey to how I got here. I don’t have a masters or a PhD, I started full time directly after college after 2x internships also at spacex doing software/automation. I was on a couple design teams in college, including Stanford solar car + mars rover. When I started spacex as a software engineer, I knew very little about fluids / propulsion engineering - I learned a lot of it on the job with some pretty incredible mentors. Then I swapped over to propulsion about halfway through my career and have been loving it ever since
