xAI Loses Last Co-Founder Amid Core Team Turmoil

Elon Musk's AI venture xAI is experiencing another wave of major personnel shifts. The company's last remaining co-founder, Tony Wu, has recently departed, marking the complete exit of xAI's original founding team less than three years after its launch. Wu previously led model architecture and core algorithm development at xAI and was a standout engineer at Google DeepMind.
All Founding Members Have Left: Vision Conflicts or Offers from Big Tech?
xAI was founded in 2023 with an initial team of 12 top experts from OpenAI, Google, and Microsoft. However, as the project evolved, founding members gradually left for various reasons. While Tony Wu's next move remains unclear, speculation points to xAI's demanding work culture or lucrative offers from other AI leaders like OpenAI or Anthropic. This steady loss of key talent raises questions about whether Elon Musk can sustain xAI's technical momentum.
Elon Musk Steps In: Will Grok's Development Be Impacted?
Despite the departure of all co-founders, Elon Musk shows no sign of slowing xAI down. The company is now heavily investing in its next-generation large model Grok-3 and continuing to expand its supercomputer cluster in Memphis. Musk has highlighted on social media that xAI has already recruited a fresh group of talented engineers from Tesla and SpaceX. Still, the complete loss of the founding team is a serious setback for any startup, especially as competition in large model architecture intensifies. Without experienced veterans, the race for Grok to catch up with GPT-5 may face greater uncertainty.
