What is the Digital Omnibus on AI?

It is a set of amendments to the EU AI Act signed on July 8, 2026, adjusting some compliance deadlines and adding a new ban on AI-generated non-consensual intimate imagery, which becomes applicable on December 2, 2026.

What should a business using AI vendors do before August 2, 2026?

The EU AI Act's Enforcement Deadline Just Arrived: What Businesses Need to Know

On August 2, 2026, the European Commission gains real enforcement power over general-purpose AI providers, with fines up to 3% of global turnover.

General-purpose AI providers have had transparency, copyright, and documentation duties under the EU AI Act since August 2, 2025. On August 2, 2026, a different threshold arrives: the European Commission's enforcement and penalty powers over those providers activate under Article 101, allowing fines of up to 3% of global annual turnover or €15 million, whichever is higher.

What Changes on August 2, 2026?

From that date, the European Commission and its AI Office can demand documentation from general-purpose AI providers, run technical evaluations of their models, mandate risk-mitigation measures, and restrict or withdraw a model from the EU market. This moves the AI Act from a disclosure regime into one with real, financially significant consequences for non-compliance.

Recent Guidance and Amendments

The Commission published guidelines on Article 50's transparency obligations on July 20, 2026, clarifying what counts as adequate disclosure for AI-generated content and AI system interactions. Separately, a Digital Omnibus on AI was signed on July 8, 2026, adjusting some deadlines and adding a new ban on AI-generated non-consensual intimate imagery, which becomes applicable on December 2, 2026.

Who Is Affected?

The enforcement powers apply specifically to providers of general-purpose AI models operating in the EU market, covering both closed models like Claude Opus 5 and GPT-5.6 and open-weight models like Kimi K3 and DeepSeek V4 when they are made available to EU users. Downstream businesses that build products on these models should confirm their vendors' compliance status, since restrictions on an underlying model can affect products built on top of it.

What Businesses Should Do Now

Confirm which AI models used in EU-facing products are covered by general-purpose AI obligations.
Request documentation on training data summaries, copyright compliance, and risk assessments from AI vendors.
Review AI-generated content disclosure practices against the July 20 Article 50 guidance.
Track the December 2, 2026 non-consensual intimate imagery ban if your product handles image or video generation.
Build a fallback plan in case a vendor's model is restricted or withdrawn from the EU market.

The Bottom Line

The AI Act's transparency rules are a year old, but August 2, 2026 is when they gain teeth. Businesses operating in or selling into the EU should treat AI vendor compliance as a real due-diligence item rather than a formality, given the size of the potential penalties and the Commission's new power to restrict access to a model outright.
