这几天到处都能刷到关于deepseek的话题，这是国产的一个ai，经过测试目前已经达到了开源模型里的一线水平，除了高性能，它还有一个标签就是经济 实惠，它的训练费用不到600万美元，运算成本比同行低了90%以上，人送外号"ai拼多多"。 便宜又厉害的模型是怎么做出来的呢？我稀里糊涂看了不少文章，过于专业，我没看懂，这题pass。 关于deepseek的第二个新闻点就有意思了，出资研发它的竟然是国内著名量化私募机构幻方，幻方的老板梁文峰持有deepseek公司83%的股权。也正是由 于这一层关系，这几天圈子里有不少人在哀嚎，说怪不得量化私募持续不断的在a股收割，原来人家早就用ai炒股，用机枪扫射还在用长矛弓箭的散户。 对此幻方倒是回应过，说deepseek团队就是专门做通用大模型的，并没有用它来炒股。话是这么说，但研究deepseek的资金和人才很多都是从幻方量化输 送过去的，能研究出成功ai模型的团队，在股票模型的开发上肯定也不弱。毕竟ai模型现在没有一个挣钱，但炒股是真挣钱。 坊间一直传闻幻方量化曾对超算集群系统投入 10 亿元，搭载了超 1 万张英伟达 A100 显卡。 然后就是今天又爆出一个热搜，说雷军 ...
