In a recent controversy surrounding Google's artificial intelligence efforts, it was reported that Jacob Devlin, a top Google AI researcher, resigned earlier this year after warning Alphabet CEO Sundar Pichai and other top executives about the training data being used for Google's chatbot competitor, Bard.
Devlin believed that the Bard team was using information from ShareGPT, a platform where users publish their conversations with Google's chatbot, ChatGPT. He feared that Bard could end up sounding too similar to OpenAI's chatbot, which would be a violation of OpenAI's terms of services. Despite Google denying the use of ChatGPT data to train Bard, Devlin left the company in January and joined OpenAI.
Devlin's departure is just one of several AI researchers who left Google at the beginning of the year to join competitors. Nonetheless, Devlin's groundbreaking research on machine learning models for search accuracy remains an important part of both Google and OpenAI's language models.
