Anthropic不会在AI用于国防的问题上退让。CEO达里奥·阿莫代昨日表示，这家AI初创公司"不能凭良 心"允许国防部在所有合法用例中不受限制地使用其模型，而五角大楼希望如此。 Anthropic一直要求国防部承诺，其模型不会被用于全自动武器或对美国民众进行大规模国内监视—— 五角大楼不愿同意这些限制。 Anthropic昨日表示，谈判仍在进行中。国防部长皮特·赫格塞斯将今日设定为Anthropic同意其部门要求 的最后期限，并威胁称，如果不同意，将把该公司列为"供应链风险"或援引《国防生产法》。 责任编辑：张俊 SF065 Anthropic不会在AI用于国防的问题上退让。CEO达里奥·阿莫代昨日表示，这家AI初创公司"不能凭良 心"允许国防部在所有合法用例中不受限制地使用其模型，而五角大楼希望如此。 Anthropic一直要求国防部承诺，其模型不会被用于全自动武器或对美国民众进行大规模国内监视—— 五角大楼不愿同意这些限制。 Anthropic昨日表示，谈判仍在进行中。国防部长皮特·赫格塞斯将今日设定为Anthropic同意其部门要求 的最后期限，并威胁称，如果不同意，将把该公司列为"供应链风险"或援 ...

01 按参数算，人脑相当于多大的模型？ 答案是：要看怎么算。 如果只看神经元的个数，人脑大概是860亿个神经元，也就是86B的模型，并不大。 参考一下，DeepSeek V3是671B，Kimi K2.5大概1000B，即1T； 但事实上人脑每个神经元又有7000个突触，从技术的角度类比，颗粒度更小的突触才更像AI模型的权重参数。 如果这么算，860亿*7000，那么人类大脑相当于大约600T模型。 而这么大的模型，今天的硬件肯定暂时还跑不动。 这么类比略糙。 但也说明——咱们这颗脑子的架构还是很复杂的，属于先进制程。 有点牛逼。 02 那么，大脑的制程到底有多先进呢？ 我随即问了Claude opus 4.6和Gemini 3.1 Pro一个问题（实在受不了GPT无比谄媚的风格）—— "如果人脑是一块芯片，那么它的制程是几纳米的？" 他们的答案出奇一致： 如果看神经元细胞体直径的直径，大概 10000-100000 纳米 (10-100微米)。 这么看大脑相当于几十年前的电子管计算机。 这TM也太落后了。 但逻辑显然不是这样的： 神经元并非一个简单的开关，它更像处理器的一个核，真正的开关和信号传递发生在突触 ...
