    另外不得不吐槽一下,老马说28年中国会产很多很多RAM,我就问你,老马的时间点什么时候对过? 另外SPACEX就是一个巨大的新云,27年10GW,算过他要融资多少钱吗?

    Figuring out how to prevent AI models from doing “rogue” things is obviously good. But I also agree with Alvaro here. We don’t know how the future will unfold, but extreme concentrated power per se is worrisome and it’s very plausible that creating strong AI will lead to that. 引用 @GroundhogStrat:So

    Great read

    Great read 引用 @arpitrage:I spent a couple of days at Anthropic learning from their folks about AI advances, and here's what I took away: • We are close to RSI (ie, models building other models) which may lead to rapid takeoff scenarios (with risks and benefits). Some evidence for this is code per

    Starlink is really that good

    Starlink is really that good 引用 @SawyerMerritt:New opinion article about @Starlink from a 7-year Delta Airlines Diamond Medallion status member (their highest loyalty tier): "After flying a United flight in July that included Starlink, it was enough reason for me to switch. It was amazing, like be

    Working out how best to use AI in mathematics research—and in science more generally—will take time, effort, and resources. We’re eager to support mathematicians as they drive scientific progress and define the future of their field. We’ve committed $5 million of funding, 引用 @SimonsFdn:How can the

    AI infrastructure 👀

    AI infrastructure 👀 "*Every* open source inference cloud I am aware of is growing faster both sequentially and YoY than either Anthropic or OpenAI. And their combined compute spend is becoming material." 引用 @GavinSBaker:TLDR; we will probably never get another ARR number from Anthropic, which is
