If artificial intelligence can truly run more efficiently, the power it needs might be less than experts assume.

The Chinese artificial intelligence (AI) company DeepSeek has rattled the tech industry with the release of free, cheaply made AI models that compete with the best US products such as ChatGPT.

In some ways, DeepSeek was far less censored than most Chinese platforms, offering answers with keywords that would often be quickly scrubbed on domestic social media. Other times, the program eventually censored itself.
