Google is replacing the leader of its consumer AI apps as the focus of the AI race shifts from the underlying models to the products built around them, according to memos reviewed by Semafor.

Sissie Hsiao, who led Google’s effort to create an AI chatbot, originally called Bard and now dubbed Gemini, will step down immediately. Josh Woodward, who leads Google Labs and oversaw the launch of NotebookLM, the company’s popular tool that turns text into a podcast-like show, will replace her.

In a memo to the staff, Google DeepMind CEO Demis Hassabis said the move will “sharpen our focus on the next evolution of the Gemini app.” He said Woodward will remain head of Google Labs while shaping the next chapter of Gemini.
