[EU AI Act Enforcement Powers Officially Take Effect, U.S. AI Giants Like Anthropic and OpenAI Face Regulatory Pressure] Deep Tide TechFlow reports that on August 4th, according to CNBC, the European Commission officially gained the authority to investigate, restrict, and impose fines on AI models this Sunday, marking the latest progress in the phased implementation of the 2024 EU Artificial Intelligence Act. Under the new regulations, the European Commission can require AI companies to submit evaluations before publicly releasing models in Europe and has the authority to restrict their market access within the EU. Non-compliant companies could face fines of up to €15 million or 3% of annual revenue (whichever is higher). The new rules apply to all companies providing general-purpose AI models within the EU, regardless of their headquarters location, and non-EU companies must designate an authorized representative within the EU. Anthropic, OpenAI, and Google are all within the scope of the new regulations. Currently, the EU has been seeking access to Anthropic's Mythos model for several months and is negotiating with OpenAI and Anthropic regarding cybersecurity issues caused by their AI models.
