DeepSeek AI Claims Spark Skepticism Over Training Cost and U.S. Tech Use

DeepSeek’s AI claims have sparked skepticism among industry experts, with concerns over its reported $5.6 million training cost and potential reliance on OpenAI’s technology. While DeepSeek asserts its models rival OpenAI’s at a fraction of the price, critics question the accuracy of its cost estimates and whether it used banned U.S. chips. Investors reacted sharply, erasing nearly $600 billion from Nvidia’s market cap. OpenAI is reviewing whether DeepSeek improperly leveraged its output data.
