the moment you realized DeepSeek is already unstoppable > DeepSeek was training with Nvidia H800 > U.S. banned H800 > They moved to H20 > U.S. banned H20 > They switched to native Huawei chips > Didn't work. Chips too weak. > They had to rewrite and recalibrate the chips from scratch > Huawei chips worked > They still partially used Nvidia H20 (what was left) for V4 but are on track to only rely on Huawei chips > China has the world's cheapest surplus electricity powered by renewables > China used to be 5 years behind, then 1 year behind, and now 3 months behind. (DeepSeek V4 ≈ frontiers in January 2026) > fully open-source > a fraction of the cost compared to frontiers > DC is scrambling to launch attack campaigns because they knew it was already too late

@hylarucoder 错过了一个亿

9) 卧槽，今天打折了。2.5 折。。。。。。。。。

开测 deepseek v4 的实际编码能力。 不定期更新。

@Jason_Young1231 ds大气啊，发布前几天冲了20，还没舍得正式用🤣

卧槽，听说大家嫌 DeepSeek-v4-pro 贵，官方直接开启2.5折活动，我们熟悉的那个价格杀手回来了！

@LufzzLiz ds很棒啊，右边的火车细节更好一些，开始以为会是gpt的

感谢大家参与，公布结果了： 左：gpt-5.5 xhigh 右：DeepSeek v4 pro 所以ds v4有些场景是真不错了，有不少小伙伴还以为右是GPT-5.5生成的呢😄

@kimmonismus @CausalEngineer yes and no 让我想起英剧 是，首相

@CausalEngineer Yes and no. ASML has an advantage, but as yesterday's release showed, less than one might think. Huawei is now also managing to develop good lithography machines, admittedly not as good as ASML, but far better than expected.

My last day in China. A reflection and summary. I have now spent four days visiting China (well, actually five days, because turkish airlines just cancelled my flight lol). It was a breathtaking experience. I saw and learned an incredible number of things, met wonderful people, had fascinating conversations, and, above all, got to know an entirely different culture. I was invited to China by XPENG and had the opportunity to visit both their headquarters and their factory on site. I already said this in another post, but what left a lasting impression on me, and at the same time makes me look at Europe with concern, is that China has a different mentality of creativity. They are experimenting with flying cars, working on FSD EVs at the same time, and developing humanoid robots; an entire product portfolio, all in parallel. While high technology once came from Europe, especially from Germany, that trend has shifted. Of course, China still depends on Western technology in certain areas. But first, it is trying to build independent production facilities and supply chains, and second, it is using this technology to go beyond what already exists. I think this can be said quite objectively. Does that mean China has already won the global competition? Not at all. But it has become an outstanding competitor. My subjective impressions of the infrastructure only reinforced this: a well-developed, modern road network, no potholes as far as I could tell, widespread digitalization, almost everything via QR codes, WeChat and Alipay, and a very high degree of domestically built and developed EVs. Germany, meanwhile, still largely wants to build combustion engines, and the broader zeitgeist still struggles with electromobility. Everyday reality embarrasses itself with problems that feel like they belong to the 20th century: letters and faxes instead of emails, physical visits to government offices instead of digital administration, infrastructure and highways plagued by never-ending repair work. Germany feels like an aging behemoth refusing to accept the future and move with the times. In many areas, China has already overtaken Germany, even if only through the strategic decision to become sovereign and independent in energy policy, something that, by contrast, is becoming almost disastrous for Germany and Europe. Does that mean everything in China is good? Certainly not. Still, for me as a European, it was a culture shock to see how outdated and backward-looking Europe appears. While China is expanding and developing its own chip production, such as Huawei Ascend, in order to become more independent from the US and NVIDIA, and while it is pushing forward into robotics and high tech, Europe seems delighted to congratulate itself on the next AI regulation or, as recently, on the misuse of emojis for supposedly illegal activities. Europe has lost touch. Full stop. But ultimately, these are political decisions. Europe has to choose: future or past, regression or progress, combustion engines, letters and regulation, or EVs, digitalization and data center expansion. Quo vadis, Europe? Time is running out. Disclaimer: I have not received any payment from XPENG; no money was transferred to me; my opinion is subjective and was expressed without compensation. P.S. I already had a negative view of developments in Europe and Germany before my trip. So it is not as if this trip fundamentally changed my view of Germany and Europe. It only made even clearer to me how much stagnation there is in Europe.

@LufzzLiz @berryxia 左边是DS？ 左边的火车的细节不太好，但是乍一看整体观看比较好

受到神佬 @berryxia 下午转发的帖子启发：我分别用gpt-5.5 xhigh 和 deepseek-v4-pro 做了个《云轨花城》的对比 先卖个关子：大家猜猜哪个是gpt-5.5 哪个是 deepseek-v4-pro ？ 单视频见评论👇 说实话我觉得deepseek-v4 已经超出预期了，还是不错的

@yuashwe 之前婚假去新西兰玩，临时起意在当地拍了一组婚纱照，拍照期间遇到的当地人都会献上祝福，很友好

一对新人可能是外滩拍婚纱照，在中行大楼旁边偶遇一个欧美旅行团，素不相识的他们一起鼓掌为新人送上祝福

@YtFlock52721 @hoshinofujivy 贴吧的表情做的真的很好

@hoshinofujivy 感觉不如

设计的终点是apple

deepseek api文档已经更新v4了 ​​​，分为deepseek-v4-flash和deepseek-v4-pro，默认开启think，思考强度有两档high和max。 * deepseek-chat 与 deepseek-reasoner 两个模型名将于日后弃用。出于兼容考虑，二者分别对应 deepseek-v4-flash 的非思考与思考模式。

@Jason_Young1231 求问codex可以不

想在 Claude 桌面版 app 使用 CC Switch 管理的供应商的朋友，可以先参考这篇文章，写的非常详细，后续我会研究能不能简化中间的操作 linux.do/t/topic/2032344

@hoshinofujivy 看到这一屏幕游戏，想起了一个段子，有人拿U盘去网吧拷了一堆快捷方式😂

那时候的草很绿，那时候的天很蓝，那时候的我们无忧无虑...那时候的时光很慢很慢....

Imagine every pixel on your screen, streamed live directly from a model. No HTML, no layout engine, no code. Just exactly what you want to see. @eddiejiao_obj, @drewocarr and I built a prototype to see how this could actually work, and set out to make it real. We're calling it Flipbook. (1/5)

“为什么要做成人形？” “为什么不加上轮子？” 哈哈哈哈

@LotusDecoder 搞差别对待，在国内肯定又得挨骂

原来智谱是一起中国和海外两个版本一起下线 老套餐啊， 我还猜想会对外国友人网开一面吧，毕竟 海外版的美元价格是国内人民币购买的好几倍。

@bxsdtk 不确定是不是V4 or V4 lite😂

@YJackong 我的专家模式1m了

deepseek web 快速模式的上下文是1M（V4？or V4 lite），但专家模式还是128K。分别生成“盒马骑自行车”，图1快速，图2专家，看起来区别不大，专家模式好像细节更多一些。

Anthropic 的哲学家@AmandaAskell 最近参加了一个访谈，在访谈中她分享了自己探索好奇领域的一个方法。 提示词大概是： 我希望你从「xx」领域里选一个大概研究生水平的概念。然后我希望你通过写一个寓言的方式，间接地把这个概念完整讲出来。最好一直到快结尾时，人才会慢慢意识到这个概念究竟是什么。然后在故事之后，再补一段解释，把你刚才真正要讲的概念说清楚。

@wangdawen58190 专家模式看起来细节更多一些，画质也好了

最新的网页expert开思考和搜索，用时163秒，比前几天短了100秒左右，质量也更好，这个很棒啊，左边的刚才生成的，右边是之前的

@zmt021 解决问题最低的成本：先把提出问题的解决了

opus4.7有一点很搞笑，就是我有个老bug，已经让cc和codex debug一个月了都没解决，交给opus4.7，他从始至终就干一件事：劝我放弃debug，项目已经很完美了
