Amid fierce competition in artificial intelligence, Elon Musk’s xAI is facing a serious talent drain. On Feb. 10–11, 2026, co‑founders Tony Wu and Jimmy Ba announced their resignations, marking that nearly half of the company’s founding team since its 2023 launch has now left. This "exodus" not only highlights potential internal tensions at xAI but also reflects the intensifying global scramble for AI talent. Reuters, the Financial Times and CNBC reported that the departures may be linked to technical pressure, company restructuring and Musk’s aggressive strategy. Once positioned as Musk’s answer to OpenAI, xAI is now struggling with a talent bottleneck — a challenge that could affect its ability to catch up with larger AI players. Here we examine the causes and consequences of the departures.
Departure details: Two key figures step down
The departures of Tony Wu and Jimmy Ba were announced via X (formerly Twitter). On the evening of Feb. 10, Tony Wu posted on X: "Today I resigned from xAI. Grateful to Elon Musk and the team." He did not give a specific reason and only expressed anticipation for the future. Just 48 hours later, on Feb. 11, Jimmy Ba posted: "It’s time to recalibrate my gradients and look at the bigger picture. 2026 will be crazy and busy, and is critical for humanity’s future." The "gradient" metaphor, drawn from machine‑learning terminology, suggests he may be seeking a new direction.
Tony Wu was an early core member responsible for technical development and model optimization and had a brief stint at OpenAI. Jimmy Ba reported directly to Musk and led much of the technical team’s work until late last year, when his responsibilities were split between Tony Wu and fellow co‑founder Guodong Zhang. The Financial Times reported that Ba’s departure may stem from tensions within the technical team: Musk pressed for rapid performance gains to catch up with competitors such as OpenAI and Anthropic, creating internal conflict. Ba did not respond to media requests for comment, and Wu likewise gave no detailed reason; both posts expressed gratitude toward Musk, avoiding public confrontation.
xAI has not issued an official response to the departures, and Musk has not publicly commented. The company’s silence is consistent with its typically low profile but has raised questions about organizational stability.
xAI’s founding team: From 12 to about half remaining
xAI was founded in July 2023, when Musk assembled 12 co‑founders to "understand the true nature of the universe" and to develop the Grok series of models. The original team included well‑known AI experts such as Igor Babuschkin (formerly of OpenAI), Kyle Kosic, Christian Szegedy and Greg Yang. However, attrition has been ongoing since the company’s founding.
- 2024: Kyle Kosic and Christian Szegedy left — Kosic without a public explanation, Szegedy to pursue personal projects.
- Aug. 2025: Igor Babuschkin departed to start his own AI safety venture capital firm.
- Jan. 2026: Greg Yang stepped back due to chronic Lyme disease to focus on recovery.
- Feb. 2026: Tony Wu and Jimmy Ba resigned.
Reuters counted that six of the original 12 co‑founders have left, a nearly 50% attrition rate. Ars Technica described the exodus as a loss of key founding talent. On X, users such as @Orgetorix shared the Financial Times coverage and discussed the impact on xAI. Global Banking & Finance Review noted that the wave of departures tests xAI’s roadmap and investor confidence.
This outflow contrasts with xAI’s rapid buildup. The company completed a $1.25 trillion merger with SpaceX in 2025 to ease the financial burden of data center and chip investments. xAI has released Grok‑1.5 and Grok‑2 and announced the Colossus supercomputer in early 2026 with training capacity of 100,000 H100 GPUs. Nonetheless, Musk’s aggressive style — including long weekly work hours and demands for rapid iteration — may have exacerbated internal friction.
Reasons for leaving: Technical pressure and industry‑wide patterns
Although Wu and Ba did not specify reasons, multiple outlets suggest internal dynamics at xAI played a role. The Financial Times reported that Ba’s departure stemmed from disputes within the technical team over model performance: Musk demanded the team overtake rivals in a short time frame, creating a high‑pressure environment. Business Insider added that Ba’s role had been split late last year, which may have caused dissatisfaction. Wu’s Slack account was reportedly deactivated before his announcement, indicating a sudden departure.
More broadly, the episode reflects the talent challenges facing the AI industry. CNBC notes that the intense workloads and uncertainty at AI startups are driving experts toward more stable platforms, as seen with Babuschkin moving into venture capital and Yang retreating for health reasons. Global shortages of AI talent are worsening: a McKinsey report showed a 30% increase in demand for AI engineers in 2025 that supply could not match. xAI’s departures are not unique; OpenAI and Anthropic have faced similar issues.
Some X users argue the exodus may be tied to Musk’s multiple commitments: xAI must compete for resources with Twitter (X), Tesla and SpaceX. The Times Of Update suggested that after merging with SpaceX xAI’s autonomy may be reduced.
Impact on xAI: Challenges and opportunities
The talent losses clearly affect xAI. Although the company’s valuation reached $24 billion, it relies on the founding team’s innovation. Shacknews warned that five founding departures could slow Grok model development and weaken xAI’s competition with OpenAI. Investor sentiment reacted: xAI’s shares dipped slightly after the news. Yet Musk’s "iron‑hand" approach might still attract new hires: the company has recruited hundreds of engineers.
For Musk, the departures increase the strain of juggling multiple major projects. xAI is central to his quest for "cosmic truth," but continued talent outflows could undermine that ambition. Industry experts say xAI needs to strengthen culture and incentive structures to retain staff.
Looking ahead: A microcosm of the AI talent war
The near‑halving of xAI’s co‑founders is just one symptom of the broader AI talent war. As the race for AGI (artificial general intelligence) heats up, expert mobility will likely rise. The next moves by Wu and Ba are unknown; they may join other startups or academia. For xAI, the SpaceX merger could provide rocket‑grade infrastructure to accelerate compute capacity. But if attrition persists, Musk’s AI ambitions may be impaired.
The episode is a reminder that AI’s future depends not only on technology but on people. Can xAI reverse its exodus? The answer may lie in Musk’s next major move. What do you think — will this talent crisis prompt a healthier ecosystem for AI in the long run?
