Overview
On August 2, 2026, Article 50 (Transparency Obligations) of the EU AI Act officially entered into force. All "interactive AI systems" serving EU users — including ChatGPT, Claude, Copilot, and customer service agents — must now comply with four core transparency requirements.
Core Requirements for Interactive AI Systems
1. Explicit AI disclosure: Systems must clearly inform users that they are interacting with an AI, not a human. 2. Machine-readable marking: All AI-generated images, video, audio, and text must carry machine-readable watermarks or metadata. 3. Prior notification: Deployers of emotion recognition or behavioral biometric classification systems must notify users in advance. 4. Public-interest disclosure: AI-generated text dealing with public-interest topics must be labeled as such.
GPAI Provider Obligations
General-Purpose AI (GPAI) model providers are now under direct jurisdiction of the EU AI Office. Compliance requirements include:
- Publishing summaries of training data content
- Disclosing copyright policies
- Documenting training data sources
- High-risk AI (recruitment, education, law enforcement, immigration): compliance deadline pushed to December 2, 2027
- High-risk AI embedded in medical devices/machinery: pushed to August 2, 2028
- All chatbot-style interfaces (ChatGPT, Claude, Cursor's Ask mode, Replit Agent, Codex CLI) must display a prominent "AI" label in the first interaction turn. Anthropic, OpenAI, Google, and Microsoft are expected to roll out EU-region prompts simultaneously on August 2.
- AI-generated media outputs — including outputs from GenCeption, Seedance 2.5, PixVerse, and ABot-World-0 — must embed metadata compliant with C2PA or equivalent standards. This is a hard constraint for Chinese vendors expanding to the EU.
- Training data transparency is now a formal compliance item. Vague statements like "we used publicly available internet data" are no longer sufficient. DeepSeek, Qwen, Kimi, GLM, and Hunyuan must prepare training data summary documents for EU listing.
- The 180+ signatories form a de facto standards pool. Non-signatories risk exclusion from EU government and institutional procurement.
- Mathematical proof outputs (classified as "auxiliary standard editing")
- Artistic, creative, satirical, or fictional content (simplified disclosure allowed as long as the work page notes AI generation)

Code of Conduct
The European Commission simultaneously published a Code of Conduct for AI-Generated Content Transparency, signed by over 180 organizations. The signatory list will be published on the Commission website. Non-signatories may face exclusion from EU public procurement.
Regulatory Context
While transparency rules took effect on August 2, 2026, the Commission announced on July 30, 2026 that compliance deadlines for high-risk AI systems have been extended:
These delays are part of the 2026 AI Omnibus simplification package. The EU is accelerating transparency enforcement for general-purpose AI while easing timelines for vertical high-risk applications.
Direct Impact on AI Coding and Agent Vendors
Exemptions and Limitations
The August 2 enforcement focuses on the transparency layer, not safety. Systemic risk provisions and model evaluation rules remain under development at the AI Office, with detailed enforcement cases expected in the second half of 2026.
The Act includes exemptions for:
Seedance 2.5-style generated film clips fall under the creative exemption — a single on-page AI-generation label is sufficient.
Practical Challenge for Chinese Vendors
The biggest operational pain point for Chinese AI vendors entering the EU is not compliance text, but training data source disclosure. Domestic Chinese-language corpora largely lack C2PA-level source marking, requiring vendors to build metadata provenance systems from scratch.
