The EU AI Act’s Digital Omnibus is now law. The European Council gave final approval on June 29, 2026, following the European Parliament’s formal endorsement on June 16. The regulation enters into force three days after publication in the EU Official Journal — publication is expected within days of the Council vote, meaning the Omnibus is already in effect or imminent as of early July.

This closes the legislative story that began with the provisional agreement on May 7. For builders and compliance teams who were tracking “expected June-July formal adoption” — that moment has arrived.

Here is what changed, what didn’t, and what you need to do in the next 30 days.

The Two-Track Story

The Digital Omnibus created two parallel realities depending on what kind of AI system you’re building:

Track 1 — High-risk AI systems: officially delayed. Standalone high-risk AI systems (Annex III use cases: employment, credit, education, law enforcement) had an August 2, 2026 compliance deadline. That date is now moved to December 2, 2027 — a 16-month extension. High-risk AI embedded in regulated products (Annex I: medical devices, machinery, lifts, radio equipment) moves from August 2, 2027 to August 2, 2028 — 12 months more.

These extensions are not provisional deals or political agreements. They are confirmed law. If your team was building compliance infrastructure against August 2, 2026 for high-risk Annex III use cases, you have until December 2027. You still need to do the work; you have more time to do it.

Track 2 — GPAI provider obligations: not delayed. General-purpose AI model obligations took effect August 2, 2025. The Commission’s enforcement powers — fines, information requests, model recalls, access demands — activate August 2, 2026. No amendment touched this date. The Omnibus deliberately left GPAI enforcement on its original schedule.

That date is 30 days away.

Who Is a GPAI Provider Under the AI Act

The regulation defines a GPAI model as a model trained on broad data, capable of serving a range of tasks, and made available to third parties. The threshold is not about size alone — it is about whether the model is placed on the market (via API, fine-tunable checkpoint, or direct product embedding) for others to use.

GPAI providers include: Anthropic (Claude family), OpenAI (GPT-5.x family), Google (Gemini family), Meta (Llama), Mistral, Cohere, AI21 Labs, and any company that distributes a foundation model others can build on.

Downstream builders — those who build applications on top of GPAI models — have lighter obligations. You are responsible for ensuring the GPAI model’s documentation is accurate for your use case, but you do not carry the provider’s full compliance burden unless you substantially modify and redistribute the model.

The practical line: if you are calling Claude/GPT/Gemini APIs to build a product, you are downstream. If you are fine-tuning and redistributing a model under your own brand as a product others build on, you may be a GPAI provider.

What GPAI Providers Must Have by August 2

Baseline obligations (every GPAI provider)

1. Technical documentation (Article 53(1)(a)) Architecture, training methodology, data sourcing and filtering, evaluation results, intended use cases, known limitations. This must be maintained continuously and submitted to the EU AI Office via EU SEND on request.

2. Instructions for use (Article 53(1)(b)) Machine-readable documentation about the model’s capabilities and limitations that downstream providers and deployers can integrate into their own compliance documentation.

3. Copyright compliance (Article 53(1)(c)) A policy implementing the EU Copyright Directive opt-outs and documenting how training data copyright obligations are handled. For models trained after August 2, 2025, this is table stakes.

4. Training data summary (Article 53(1)(d)) A publicly available summary of the content used for training. This is not the full dataset — it is a described overview sufficient for public accountability and for downstream builders to assess copyright exposure.

Additional obligations for systemic risk models

A GPAI model carries “systemic risk” designation when cumulative training compute exceeds 10²⁵ FLOPs (floating point operations). If your model reaches this threshold, you must notify the EU AI Office within two weeks.

Systemic risk GPAI providers must additionally:

  • Adversarial testing: Conduct model evaluations and red-teaming specifically targeting systemic risk scenarios — not just standard capability benchmarking.
  • Incident reporting: Track and report serious incidents and corrective measures to the AI Office without undue delay.
  • Cybersecurity measures: Document and maintain security protections appropriate to a model with systemic risk potential.

The compute threshold currently captures the frontier: GPT-5.6 Sol, Claude Fable 5, Gemini 3.5 Pro, Grok 4.5 and their successors are likely at or above it. Mid-tier models from major labs may be approaching it.

The Code of Practice and What Signing It Does

The EU AI Office published the final GPAI Code of Practice in July 2025. The Code is voluntary. However, providers who adhere to it receive a presumption of compliance with Articles 53 and 55 of the AI Act.

This is meaningful: it shifts the enforcement burden. Instead of the Commission having to prove you met each obligation, you have a documented record of following the established voluntary standard, and the Commission must demonstrate departure from it to impose liability.

Major providers — Anthropic, OpenAI, Google DeepMind, Meta, Mistral — participated in the Code’s drafting. Signing it does not require separate documentation for each obligation; it incorporates the Code’s procedures as your compliance framework.

If you are a GPAI provider who has not engaged with the Code of Practice: the 30-day window before August 2 is the time to assess whether signing serves your compliance posture.

30-Day Action Checklist

If you are a downstream builder (API consumer):

  • Confirm your GPAI providers have documentation you can reference — most major providers publish this
  • Check that your deployment documentation references the upstream GPAI model and its known limitations where relevant to your high-risk use cases
  • Note the high-risk AI extension: your Annex III deadline is now December 2, 2027, not August 2, 2026 — but foundational documentation work started now is not wasted

If you are a GPAI provider (distributing a model to third parties):

  • Finalize technical documentation to Article 53(1)(a) standards — architecture, training data sourcing, evaluations, limitations
  • Publish the training data summary (Article 53(1)(d)) — publicly available, not confidential
  • Ensure instructions for use are machine-readable and current
  • Register for EU SEND (the secure submission platform) if not already done — documents are submitted here on request
  • Check compute count: are you at or approaching 10²⁵ FLOPs? If yes, initiate systemic risk notification workflow
  • Evaluate the GPAI Code of Practice and decide whether to sign

If you are a systemic risk GPAI provider:

  • Adversarial testing documentation ready for submission?
  • Incident tracking pipeline in place (what qualifies as “serious incident” per the AI Office guidelines)?
  • Cybersecurity controls documented?
  • Have you verified the two-week notification deadline mechanism is operational?

Fines Starting August 2

When enforcement activates, the Commission can:

  • Request information from GPAI providers (compliance audits)
  • Order access to model internals for evaluation
  • Mandate corrective measures or recall
  • Impose fines

Fine scale:

  • GPAI non-compliance (Article 53 baseline): up to €15 million or 3% of global annual revenue, whichever is higher
  • Systemic risk non-compliance (Article 55): up to €35 million or 7% of global annual revenue
  • Providing incorrect or misleading information to the AI Office: up to €7.5 million or 1% of revenue

For a company with $5 billion in global revenue, 3% is €150 million. For frontier labs, these are material numbers.

The Commission is not expected to launch enforcement actions on August 2 — regulators typically use initial enforcement periods to investigate and gather information. But the legal exposure exists from that date, and the first formal information requests and compliance inquiries are plausible within weeks of August 2.

What Else Changed in the Omnibus

SME relief expanded: The simplified compliance framework now applies to companies with up to 750 employees and €150 million in annual revenue — up from the original 250-employee / €50M revenue threshold. Benefits include simplified guidance, reduced fines, regulatory sandbox access, and standardized documentation templates.

New bans (effective December 2, 2026): The Omnibus adds explicit bans on AI systems designed to generate non-consensual intimate imagery and AI-generated child sexual abuse material. These are not new legal concepts — they were addressed through other EU law — but the AI Act now directly prohibits deploying AI systems built specifically for these outputs.

Transparency obligations (Article 50) — partially moved: Synthetic content marking requirements (watermarking and labeling of AI-generated content) are deferred from August 2, 2026 to December 2, 2026 — a four-month extension.

What Doesn’t Change

The GPAI obligations timeline is unchanged. The Commission’s enforcement powers activate August 2. The AI Office is operational and has been receiving Code of Practice submissions, publishing guidance, and building enforcement infrastructure since mid-2025.

The high-risk AI extension is real and confirmed, but it is not a general reprieve for all AI compliance. Builders who read the May 7 provisional agreement and concluded “EU AI Act compliance is delayed” should revisit that reading: GPAI enforcement is on schedule, transparency obligations move four months, and high-risk AI moves 16 months.

The August 2 date is 30 days away. That is a sprint, not a runway.
