EU AI Act GPAI Compliance Deadline: OpenAI, Google, Anthropic and Meta File Transparency Reports

Think of the EU AI Act as a mandatory product label for powerful AI systems — the kind that can write, reason, generate images, and answer complex questions. These are called GPAI models, short for General Purpose AI.

Starting June 11, 2026, any company building these models — OpenAI with ChatGPT, Google with Gemini, Anthropic with Claude, and Meta with Llama — must complete three key steps: register in an official European database, publish a transparency report explaining how their model works and what risks it carries, and prove they have adequate safety measures in place.

It is similar to how household appliances must display safety ratings, energy consumption figures, and usage warnings. The AI Act wants the same level of accountability for AI models, but instead of watts and voltage, regulators want to know how much data was used to train the model, whether copyrighted material was included, and what the known dangerous use cases are.

For everyday users and businesses, this means your AI tool provider now has to demonstrate compliance on request. Companies that ignore these rules face fines of up to 3% of their worldwide revenue — for firms like OpenAI or Google, that translates to billions of euros. This is no longer just regulation on paper; it is the first moment the rules are actively enforced.
