Europe's AI Office gained live supervisory powers over general-purpose AI models as the AI Act's next phase took effect, CNBC reports. The Commission can demand model evaluations before EU release, restrict market access, and fine providers up to 15 million euros or 3 percent of annual turnover, whichever is higher. Counsel say the rules reach non-EU labs that offer GPAI in Europe and that blocking an information request is itself fineable. OpenAI says it is working with the Commission on Codes of Practice; Google pledged compliance. Caveat: high-risk system duties were separately delayed toward late 2027, so the sharpest product-level obligations remain staggered.
