It’s not the BBC’s job to be an authority. Their job is to report what the (relevant) authorities are saying:

DeepSeek challenged certain key assumptions about AI that had been championed by American executives like Sam Altman, CEO of ChatGPT-maker OpenAI.

“We were on a path where bigger was considered better,” according to Sid Sheth, CEO of AI chip startup d-Matrix.

Perhaps maxing out on data centres, servers, chips, and the electricity to run it all wasn’t the way forward after all.

Despite DeepSeek ostensibly not having access to the most powerful tech available at the time, Sheth told the BBC that it showed that “with smarter engineering, you actually can build a capable model”.

That said, seems suspect that an AI startup CEO is getting this much airtime. I would have preferred an industry analyst or an AI researcher.
