EU AI Act enforcement powers over general-purpose AI set to take effect August 2, 2026

With the window closing on a major EU compliance milestone, trackers and the European Commission reaffirmed that on August 2, 2026 the bulk of the EU AI Act's remaining provisions begin to apply, except Article 6(1). Most consequentially for the MODELS beat, the European Commission's enforcement powers over providers of general-purpose AI (GPAI) models—Chapter V—enter into application that day. Those powers include requesting information, requesting access to a model to conduct evaluations, requiring risk-mitigation measures, and issuing fines of up to 3% of global annual turnover or EUR 15 million, whichever is higher (or, alternatively, requiring a provider to restrict, withdraw or recall a model).

The August 2026 date also activates the GPAI fines framework, imposed directly by the Commission under Article 101, alongside notified-body oversight under Chapter III. The Act's GPAI obligations technically became applicable on August 2, 2025, but models already on the market before that date have until August 2, 2027 to comply, and the Commission's hard enforcement teeth arrive in 2026. The framework targets large foundation models—explicitly including GPT, Gemini, Claude and Llama—requiring transparency documentation, copyright policies and, for models posing 'systemic risk,' additional adversarial testing and incident reporting.

The looming date is significant because it converts the AI Act's GPAI rules from guidance-backed obligations into directly enforceable ones for frontier developers operating in the EU, contrasting with the voluntary, defender-focused approach the US adopted via its June 2 executive order. Industry attention through May 2026 centered on finalizing transparency reporting and the GPAI Code of Practice ahead of the deadline.
