Chinese AI startup DeepSeek has released two new models that reportedly match or exceed OpenAI’s GPT-5. The powerful systems are also completely free. This move could reshape the fierce AI competition between American and Chinese tech firms. DeepSeek claims its models achieve top results by using a new architecture that substantially reduces computing costs for complex tasks. One model has already won gold medals in elite international math and coding competitions, demonstrating its abilities without internet access. This technical success arrives as the company faces growing regulatory challenges in Europe and America over data security and its Chinese origins.
