Song Xiaodong’s team left Meta after four months of collaboration, a source familiar with the matter said, citing "work style misalignment".

Insight: Beating AI Flash News – According to Semafor, Meta is laying off a batch of employees it hired in June this year from AI security startup Virtue AI, with the partnership lasting only about four months. Meta spokesperson Andy Stone told Semafor that the relevant personnel were let go due to "work style misalignment" and the collaboration did not develop as expected. In June this year, Dawn Song, a UC Berkeley computer professor and founder of Virtue AI, announced she would join Meta’s Superintelligence Labs, along with Virtue AI co-founders Bo Li, Sanmi Koyejo and other team members. The hiring was reported as Meta bringing in an independent team rather than acquiring the entire Virtue AI. Virtue AI mainly focuses on AI security testing, red teaming, vulnerability discovery, as well as model runtime protection and governance. Meta’s earlier recruitment of the team was seen as aligned with its advancement of AI agent and superintelligence strategies, and efforts to strengthen AI security and frontier risk governance. Semafor reports that Meta stated the Superintelligence Labs will continue to focus on AI security, alignment and frontier risks. However, Meta did not disclose the specific disagreements between the two sides, nor has it confirmed whether core Virtue AI members like Dawn Song have all left Meta. As of the report’s publication, Virtue AI has not responded. The report notes that the rapid shift in this partnership has once again sparked external discussion on the "organizational mismatch" issue when top research teams enter large tech companies – referring to potential conflicts between the autonomy, flexibility and high decision-making efficiency that startup teams are accustomed to, and the organizational processes and corporate culture of large tech firms.
