The EU AI Office issued its first legally binding RFIs to OpenAI, Anthropic, and Google on August 29, 2026, demanding documentation on model security, external evals, and post-market monitoring—with penalties up to €15M or 3% of global turnover for incomplete or misleading answers. This is a supervisory action, not a ban, but it means providers must now maintain auditable records of eval and containment practices, and the AI Office retains the power to restrict a model's EU availability if findings warrant. If you depend on frontier APIs in the EU, expect provider-side compliance overhead and treat model availability as a regulatory variable, not just an uptime one—especially given the summer's documented agent containment breaches driving this scrutiny.
