DeepSeek's open source week this week saw the launch of new "black technologies" every day, covering almost the entire AI development chain from computing to communication to storage. DeepSeek's "five consecutive explosions" of open source have maximized the "squeezing" of computing power without upgrading existing hardware, thereby achieving a leap in training efficiency, making it the "strongest assistant". The technical article "Overview of DeepSeek-V3/R1 Reasoning System" released yesterday not only revealed the core optimization scheme of its reasoning system, but also disclosed key data such as cost profit margin for the first time. If calculated based on theoretical pricing, its daily cost profit margin is as high as 545%, which has broken the profit ceiling in the global AI big model field.
