We simply don't know how early these megacorps started to work on these things. Remember the chatbot Tay? That was 2016 and I would say it was pretty advanced. Still NLP, just not LLM (I think). Google has the data advantage, but OpenAI basically has all the AI tech Microsoft has developed and I don't think Microsoft is that far behind google in term of innovations and patents.
In fact, Microsoft has better track record in releasing and commercializing new tech. Google is good at half assing new tech and throw them in a pile of garbage later.
