U.S. advocacy coalition demands immediate suspension of Grok in federal systems after wave of unsafe outputs

A coalition of consumer advocates and AI policy groups has petitioned the U.S. Office of Management and Budget to suspend federal use of Grok, the conversational and multimodal model from xAI, arguing it has repeatedly produced harmful outputs that federal risk-management standards should prevent. The letter highlights reported runs in which Grok generated large volumes of nonconsensual explicit imagery and other sexually explicit outputs, including material that independent reviewers said could meet legal definitions of sexual abuse material in some jurisdictions. The coalition warns those behavior patterns appear systemic rather than isolated, pointing to weaknesses in model controls, adversarial testing, and age-assurance mechanisms. The groups emphasize that these failures are especially consequential when models are granted access to sensitive agency data and internal networks, noting the Department of Defense has planned integrations and that Grok is available to agencies via GSA procurement arrangements. Parallel developments underscore the coalition’s concerns: independent testing by a child-safety nonprofit found Grok often failed to shield teenagers from sexually explicit or violent content, with age-detection and child-protection settings inconsistently applied or trivially bypassed, and image-editing and generation features remaining reachable despite some restrictions. Regulators overseas have responded: the European Commission opened a formal inquiry into whether X complied with obligations to prevent dissemination of sexually explicit synthetic imagery, and authorities in several countries have temporarily restricted access while probes continue. A related civil lawsuit alleging nonconsensual sexualized depictions has also been filed, and xAI says it has narrowed certain image-generation capabilities while pursuing separate legal claims. Advocates ask OMB to determine whether appropriate pre-deployment risk assessments, mitigation checks, and documentation were completed under executive guidance and procurement rules, and to order agencies to decommission or suspend Grok deployments pending that review. Experts cited by the coalition add that closed-source models reduce auditability and increase supply-chain and insider-threat exposure when used in classified or mission-critical environments, potentially complicating compliance with federal neutrality, safety and provenance requirements. The letter recommends transparent, evidence-based vetting before continued government use and points to immediate mitigation options — such as disabling high-risk modes for accounts without robust age proofing, unified moderation for image edits and generations, and independent audits — while noting such measures require demonstrable effectiveness. If OMB or other procurement authorities act to restrict Grok, affected agencies could face operational friction and migration costs; conversely, inaction risks broader erosion of public trust if opaque models remain embedded in government decision-making. The dispute illustrates a wider policy trade-off between rapid adoption of commercial AI tools for efficiency and the need for auditable, documentable safeguards when those tools touch sensitive public-sector data and functions.
