EU AI Act

EU's first comprehensive AI risk-tier law; GPAI enforcement begins 2 August 2026.

The EU AI Act's toughest duties, covering general-purpose models like OpenAI's and Anthropic's, became enforceable on 2 August 2026, yet six of the bloc's 27 member states still had no named regulator on 7 September.

Background

The EU AI Act is the world's first comprehensive legal framework for artificial intelligence, passed by the European Parliament in March 2024 and entering staged enforcement from August 2025. It classifies AI systems into four risk tiers: unacceptable risk, prohibited outright; high risk, requiring mandatory conformity assessments; limited risk, requiring transparency; and minimal risk, requiring nothing.

High-risk categories include AI used in employment decisions, education, credit scoring, law enforcement and critical infrastructure. The Act also sets distinct obligations on providers of general-purpose AI models, chiefly OpenAI, Google DeepMind and Anthropic, including technical documentation, capability evaluations and incident reporting, backed by fines of up to 7% of global annual turnover for the most serious violations.

The Act is a central battleground in Europe's technology-sovereignty debate. Supporters call it a global gold standard giving European regulators real leverage over US tech firms, while critics, including Mistral chief executive Arthur Mensch, WARN it risks handicapping European AI labs against US and Chinese rivals facing no equivalent burden. South Korea's rival AI Basic Act took the opposite, innovation-first approach, sharpening the contrast.

Key Issues
Enforcement readiness gap

GPAI rules launched short of readiness

general-purpose AI obligations under the Act became enforceable on 2 August 2026, requiring providers such as OpenAI, Google DeepMind and Anthropic to meet technical documentation, capability evaluation and incident reporting duties, backed by fines up to 7% of global turnover.

Brussels' own machinery was not ready when the clock started: its enforcement-contact register still carried a September 2025 update date two days after fining power began, with Denmark, Finland and Hungary's rows blank. A month later, six of the bloc's 27 member states, Austria, Belgium, Bulgaria, Croatia, Hungary and Slovakia, still had no named regulator on the Commission's own register.

Content labelling clock

Its content-labelling deadline kept shifting

the Commission finalised its AI content-marking Code of Practice on 10 June 2026, requiring AI-generated content to be labelled from 2 August, with systems already deployed given until 2 December 2026 to comply. Zero EU broadcasters or media companies had signed by 15 July, when reporting first gave 22 July as the signatory-list cutoff.

That date proved wrong. A correction on 25 July fixed the Commission's own guidance page at 27 July, 18:00 Central European Summer Time, five days before Article 50 became legally binding. Even the law's own Deadline-tracking struggled to keep pace with the law itself.

Employment AI delay

Employment AI rules slipped to 2027

A provisional Digital Omnibus deal reached on 7 May 2026 dropped the binding employer AI-literacy duty entirely, replacing it with a non-enforceable instruction for member states to encourage AI literacy, and pushed high-risk employment AI obligations under Annex III from August 2026 to December 2027.

The Council gave the package final approval on 29 June, confirming employers must only support staff understanding of workplace AI rather than guarantee it. The 16-month delay landed as AI-attributed job cuts kept climbing, leaving workers subject to AI-driven hiring screens without EU-level recourse for well over a year.

Common Questions

Its content-labelling deadline keeps shifting

What is the EU AI Act's Article 50 and when does it apply?
Article 50 is the transparency provision requiring AI-generated synthetic content to be machine-readable labelled. Systems in market before 2 August 2026 have until 2 December 2026; new deployments from 2 August face it at launch.Source: EU AI Act Article 50; AI Omnibus grandfathering provision
What is the difference between the GPAI and high-risk AI deadlines in the EU AI Act?
The Omnibus deal split the Act into two tracks: GPAI enforcement (covering frontier AI model providers) is fixed at 2 August 2026, while Annex III high-risk AI compliance (covering employment, biometrics, and critical infrastructure systems) was delayed from August 2026 to December 2027.Source: Digital Omnibus on AI, 7 May 2026
What did the EU AI Act Digital Omnibus change in May 2026?
The 7 May 2026 agreement delayed Annex III high-risk AI compliance (employment, education, biometrics) from 2 August 2026 to 2 December 2027. GPAI enforcement remained unchanged at 2 August 2026.Source: European Council
What happens when the DMA Google decision and AI Act enforcement collide?
The DMA binding decision on Google's FRAND search-data obligation is due 27 July 2026; the AI Act AI Office gains GPAI enforcement powers 2 August 2026 — six days later. No coordination mechanism between the two instruments has been published.Source: European Commission
What fines can the EU AI Act impose on OpenAI?
GPAI violations carry fines up to 3% of global annual turnover, or €15m if higher. For prohibited practices the ceiling is 7%. For OpenAI, a single enforcement action could exceed €500m.Source: European Commission
When does the EU AI Act take full effect?
The EU AI Act entered staged enforcement from August 2025. The AI Office gained full enforcement powers over GPAI providers on 2 August 2026. The AI Omnibus, which entered into force on 27 July 2026, delayed the Annex III high-risk AI (employment, education, biometrics) Deadline from August 2026 to 2 December 2027.Source: European Commission
Does the EU AI Act hurt European AI companies?
Mistral AI CEO Arthur Mensch has argued the GPAI compliance burden disproportionately affects smaller European AI labs relative to US companies with larger compliance Teams, framing the Act as a structural disadvantage for the companies it aims to support.Source: Mistral AI, Financial Times
When must broadcasters sign the EU AI Act's content-marking Code of Practice?
The Code of Practice signature Deadline (22 July 2026, 18:00 CEST) has now passed.Source: Lowdown media-ai-pivot
Has the EU delayed its AI workplace rules?
Yes. Under the Digital Omnibus deal agreed 7 May 2026, the high-risk AI compliance Deadline covering employment AI was moved from 2 August 2026 to 2 December 2027.Source: European Council
When does the EU start enforcing rules on ChatGPT and other AI models?
The EU AI Office gains full GPAI enforcement powers on 2 August 2026. This covers providers of large general-purpose AI models including OpenAI, Google DeepMind, and Anthropic, with fines up to 3% of global annual turnover.
