xAI co-founder departures deepen as another exit looms
xAI has lost co-founder Zihang Dai, according to multiple US media reports, adding to a series of senior exits from Elon Musk’s AI start-up. Another co-founder, Guodong Zhang, has reportedly told colleagues he plans to leave, though his departure has not yet been formally confirmed.
The company, launched in 2023 to compete with OpenAI, Google and Anthropic, is best known for its Grok language models integrated into Musk’s X platform. Several founding researchers and early architecture leads have already moved on since early 2026. Zhang’s potential exit is notable as he heads key engineering work on coding tools and developer products built on Grok. While churn at young tech firms is common, the pace at xAI underlines the tight market for experienced AI talent as companies pour billions into chips, data centres and infrastructure to train and run large language models.
