DeepMind clearly is a household name. Think of AlphaGo or AlphaFold, those were legendary. Google Brain as well is a household name. Think of the Transformer, or BERT. Those are legendary, as well.
I'm sorry, but no. DeepMind might be well known to AI nerds, but it's not a household name the same way ChatGPT/OpenAI has become.
No one in the public knows what those are but most people have heard of ChatGPT at this point.
