AI disclosure requirements in Hungary: what applies since 2 August 2026
The EU AI Act's transparency obligations are a Union-wide regulation, so the substance is the same in Hungary as everywhere in the EU: from 2 August 2026, AI systems that interact with people must disclose they're AI, synthetic media must carry machine-readable marking, and deepfakes and certain AI-generated public-interest text must be labeled. What differs country by country is who enforces it, in what language your users encounter it, and how quickly complaints turn into questions.
Enforcement in Hungary
Hungary's Act LXXV of 2025 has been in force since 1 December 2025, making it one of the earlier national AI Act implementing laws in the EU, though two provisions (Section 3(2) and Section 10) are held back until 2 August 2026, aligning with Article 50 itself. The National Accreditation Authority (NAH) is the notifying authority, accrediting the conformity-assessment bodies that certify high-risk AI systems. The Minister responsible for Enterprise Development, within the Ministry of National Economy, is the primary AI Market Surveillance Authority and single point of contact, investigating non-compliance, ordering corrective measures, and overseeing the national regulatory sandbox, which is due to be fully active by August 2026. A new Hungarian Artificial Intelligence Council provides strategic guidance and cross-government coordination. Article 50 applies from 2 August 2026 with the EU's penalty ceiling of €15 million or 3% of worldwide turnover.
The four duties, as they show up on your site
- Article 50(1): chatbot disclosure
- Any AI system interacting with visitors must make that clear no later than the first interaction, in a clear and distinguishable way.A line in your terms doesn't satisfy it.
- Article 50(2): machine-readable marking
- AI-generated audio, images, video, and text must be marked in a machine-readable, detectable format.For generative systems already on the market before 2 Aug 2026, this specific duty has a transition until 2 Dec 2026; the rest does not.
- Article 50(3): emotion recognition & biometric categorisation
- People exposed must be informed the system is operating.
- Article 50(4): deepfake and AI-text labels
- Visible disclosure for deepfakes, and for AI-generated or manipulated text published to inform the public on matters of public interest.
Hungary-specific practicalities
- Hungary's supervision runs through a government ministry (Enterprise Development) rather than an independent regulator, expect a more centrally-directed enforcement posture than in member states using arm's-length agencies
- The law itself has been live since December 2025, so the institutional machinery (single point of contact, sandbox, Council) has had a runway to mature well before Article 50's own August 2026 start date
- The regulatory sandbox reaching full activation by August 2026 makes it a realistic pre-launch option for testing a disclosure or labelling approach before EU-wide enforcement begins
- Keep the Hungarian-language first-interaction screenshot in your evidence file, dated, alongside your widget settings export
Disclosure language should match your user-facing language. For a site serving Hungary in Hungarian, a first-message line such as "Ön egy mesterséges intelligencia (AI) asszisztenssel beszélget" (you're chatting with an AI assistant) is the pattern to aim for, at first interaction, not in the általános szerződési feltételek.
Common questions
Is Hungary's AI law fully in effect now?
Most of Act LXXV of 2025 has been in force since 1 December 2025; two specific provisions were held back until 2 August 2026 to align with when Article 50 and the wider AI Act framework start applying.
Who enforces Article 50 in Hungary day to day?
The Minister responsible for Enterprise Development, inside the Ministry of National Economy, is the designated AI Market Surveillance Authority and single point of contact, the body most likely to receive and route a chatbot-disclosure or labelling complaint.
