The European Commission's power to enforce the AI Act against general-purpose model providers goes live on August 2 — a year after the obligations took effect
On 2 August 2026 the Commission's AI Office gains the standing to investigate general-purpose AI providers, order corrective measures, and impose fines of up to €15 million or 3% of worldwide turnover. The obligations have been law since August 2025; for twelve months they existed with no regulator able to act. That gap closes this week — and it closes retroactively, because the rules were never suspended.
The substantive event is the enforcement switch, not a rule change. Every general-purpose model shipped into the EU market since August 2025 has been accruing compliance exposure against a regulator that could not yet move. That asymmetry ends on Saturday, and the Article 50 transparency duties — telling users when they are talking to a machine or looking at synthetic media — become directly finable at the €15M-or-3% ceiling.
The relief valve is narrower than the headlines. The Digital Omnibus signed 8 July pushed stand-alone high-risk Annex III systems to 2 December 2027 and product-embedded AI to 2 August 2028, so the hardest obligations are deferred. But the general-purpose duties are not among the deferred set: they land now, and the training-data summary requirement is the one most labs, open-weight included, have been least willing to satisfy.
The procurement read for H2 2026 is that EU-market compliance stops being a roadmap slide and becomes a gating line in vendor selection. Enterprises buying model access into European operations now have a named regulator and a date to point at, and the vendor questionnaires will grow a training-data-summary field within the quarter.
