金吾财讯 | 中信建投发研报指，根据DeepSeek披露，2月27日至2月28日的24个小时内，DeepSeek-V3和R1推理服务总成本为87072美元/天。若所有tokens的输入和输出全部按照DeepSeek R1的定价计算，理论上DeepSeek一天的总收入为562027美元，成本利润率高达545%。但由于DeepSeek-V3定价低于R1，且网页端和应用程序免费，仅部分服务产生收入，再加上非高峰时段设有夜间折扣，其实际收入不及理论数值。该行表示，当前市场主要的关注点在于AI大模型的训练和推理成本大幅下降，是否会影响对于算力基础设施建设的需求。我们认为从长期来看，算力成本的下降是AI大模型应用爆发的必要条件，当前国内外云厂商均大幅增加资本开支，需求端有较为强力的支撑要素，建议继续重点关注算力基础设施产业链。
