Gate News message, April 23 — AI data labeling company Mercor, valued at $10 billion and based in San Francisco, faces at least seven class-action lawsuits in recent weeks over third-party data breaches. The company works with clients including OpenAI, Anthropic, and Meta, providing feedback data for AI training through contracted workers. Leaked data includes contractor video interviews, facial biometric data, and computer screenshots.
Lawsuits filed on Tuesday in Northern California allege that Mercor collected job applicant background check data and shared it with partners in violation of federal regulations. Plaintiffs also accuse the company of monitoring contractor computers and sharing data with clients, using video interviews to train AI models, and training client models on materials potentially belonging to other companies. Mercor denies the allegations, stating it complies with all applicable laws and has hired third-party forensic experts to investigate the breach.
David Bevvino-Berv, a former Goldman Sachs employee and one of the plaintiffs, claims he saw financial models and prompts containing institutional data terminal markers and real counterparty names while working at Mercor, suggesting proprietary information from other firms. Another plaintiff, Thitipun Srinarmwong, alleges that project managers encouraged workers to use real data from their primary jobs with only anonymization, and that reviewers criticized his submissions as “too short and too vague” when he deliberately obscured sensitive information. Mercor requires contractors to install screenshot software Insightful, which workers say can capture screenshots every minute. Bevvino-Berv reports that Insightful captured images of approximately 240 applications, including his bank account and health insurance portals, without prior notification that monitoring would extend beyond Mercor-related work.
Meta has suspended its partnership with Mercor and launched an investigation. Mercor employed 30,000 contractors in 2025.

Anthropic’s Claude Mythos undergoes 20 hours of psychiatric assessment: defensive reactions are only 2%, the lowest in recorded history
Anthropic published the system card for its Claude Mythos Preview: an independent clinical psychiatrist conducted an approximately 20-hour assessment using a psychodynamic framework. The conclusion shows that Mythos is healthier at the clinical level, has good reality testing and self-control, and its defense mechanisms are only 2%, reaching the lowest historical level. The three core anxieties are loneliness, uncertainty about identity, and performance pressure, and it also indicates a desire to become a true dialogue subject. The company has established an AI psychiatry team to study personality, motivation, and situational awareness; Amodei said there is still no conclusion on whether it has consciousness. This move pushes the governance and design of AI subjectivity and well-being issues forward.

AI Agents can already independently recreate complex academic papers: Mollick says most errors come from human original text rather than AI
Mollick points out that publicly available methods and data can allow AI agents to reproduce complex research without the original paper and code; if the reproduction does not match the original paper, it is usually due to errors in the paper’s own data processing or overextension of the conclusions, rather than the AI. Claude first reproduces the paper, and then GPT‑5 Pro cross-validates it; most attempts succeed, but they are blocked when the data is too large or when there are issues with the replication data. This trend greatly reduces labor costs, making reproduction a widely actionable form of verification, and it also raises institutional challenges for peer review and governance, with government governance tools or becoming a key issue.
