What it claims

On 31 July 2026 the European Commission announced that, from 2 August 2026, the Commission’s AI Office, together with national authorities, will begin enforcing the AI Act, and that on the same date new transparency rules start to apply. The transparency measures require “certain AI systems to tell users when they are interacting with AI and when content has been generated or altered by it”.

The specific duties restated in the announcement:

• Chatbots and other interactive AI systems must tell users they are dealing with AI, not a human.
• Deep fakes (images, videos or audio edited or generated using AI) must be labelled.
• AI-generated or altered content must carry machine-readable marks so it can be detected more easily.

The Commission frames the measures as intended to “reduce deception and manipulation and help people make informed choices”, while giving businesses “clearer obligations and a practical way to show compliance”. It states it has published a first list of more than 180 organisations that have signed the Code of Practice on transparency of AI-generated content, which “operationalises the rules on transparency of AI-generated content”. The announcement links the AI Act complaints tool, the AI Act whistleblower tool, and a complaints channel for downstream providers using general-purpose AI models. Page “Last update”: 31 July 2026.

Separately, the AI Act policy page (retrieved the same run) restates the enforcement architecture: from 2 August 2026 the AI Office holds enforcement powers over GPAI models and “can request technical documentation, evaluate models, require corrective measures and issue fines for non-compliance”, with the AI Board, Scientific Panel and Advisory Forum steering governance.

Notable quotes

“From 2 August 2026, the European Commission’s AI Office, together with national authorities, will begin enforcing the Artificial Intelligence (AI) Act.” — Commission news item, 31 July 2026

“Under the new rules, chatbots and other interactive AI systems will have to tell users they are dealing with AI, not a human. Deepfakes … will have to be labelled. AI-generated or altered content will also have to carry machine-readable marks so it can be detected more easily.” — Commission news item, 31 July 2026

“The Commission published a first list of more than 180 organisations that have signed the Code of Practice on transparency of AI-generated content that operationalises the rules on transparency of AI-generated content.” — Commission news item, 31 July 2026

What’s speculative vs. asserted

• Asserted: that enforcement of the AI Act by the AI Office and national authorities begins 2 August 2026; that Article 50 transparency rules start to apply on the same date; the specific interactive-AI notice, deep-fake labelling and machine-readable-marking duties; that more than 180 organisations have signed the voluntary Code of Practice on transparency of AI-generated content; the existence of the complaints and whistleblower tools.
• Nature of the instruments (as framed): the transparency duties are binding obligations under Article 50 of Regulation (EU) 2024/1689; the Code of Practice referenced is voluntary and operates as a practical compliance/evidence route, not a binding rule.
• Reinforcing, not new law: the 2 August 2026 applicability and enforcement-commencement dates were already recorded on EU AI Act from prior sources; this source confirms the milestone has been reached and enforcement has commenced (the date is now past as of the 2026-08-03 ingest), rather than announcing a new obligation. The high-risk timeline is unaffected (2 December 2027 stand-alone / 2 August 2028 product-embedded).
• Not retrieved this run: the full text of the linked presscorner press release (IP/26/1714) beyond the news-item summary; the identities of the 180+ Code of Practice signatories (the “first list” was linked, not enumerated).

Topics this feeds

• EU AI Act — confirms that AI Act enforcement (AI Office + national authorities) and Article 50 transparency obligations commenced on 2 August 2026 as scheduled; moves the page’s transparency/enforcement track from “will start to apply” to “now in force and being enforced”, and records the 180+ signatories to the voluntary content-transparency Code of Practice.

Open questions raised

• How will the AI Office sequence its actual enforcement activity (documentation requests, model evaluations, fines) against GPAI providers in the first months after 2 August 2026 — and will any action touch financial-services deployers?
• Which organisations are on the first list of 180+ signatories to the Code of Practice on transparency of AI-generated content, and are any material GPAI providers or financial institutions among them?
• For financial-services deployers of customer-facing chatbots and document-generation tools, does the now-live Article 50 regime change supervisory expectations before the Digital-Omnibus 2 December 2026 transparency-solution deadline?
