OpenAI says Chinese rivals using its work for their AI apps

The maker of ChatGPT, OpenAI, has complained that rivals, including those in China, are using its work to make rapid advances in developing their own artificial intelligence (AI) tools.

The status of OpenAI - and other US firms - as the world leaders in AI has been dramatically undermined this week by the sudden emergence of DeepSeek, a Chinese app that can emulate the performance of ChatGPT, apparently at a fraction of the cost.
