The European Parliament is piloting an internal AI platform, called EPGenAI Hub, designed to pull staff off public chatbots and onto vetted systems — while leaving a transparency gap that has drawn criticism from lawmakers themselves.
A tiered menu of models
According to a report by Politico, the European Parliament is testing the hub now and could begin a full rollout as early as September 2026. For sensitive material, staff can choose systems hosted on Parliament’s own infrastructure — Meta’s open-weight Llama, OpenAI’s GPT-OSS, and Mistral Small. For heavier tasks, they can reach externally-hosted services such as ChatGPT and Anthropic’s Claude Sonnet.
Why Parliament built it
About 2,100 staff — roughly a fifth of the workforce — already use AI daily, largely by pasting draft amendments, speeches, and parliamentary questions into public tools with no institutional oversight, the report said. That habit has reportedly produced a surge in amendments needing translation, legislative text with a recognizably AI-generated cadence, and citations to laws that don’t exist.
Brando Benifei, one of the lead negotiators behind the EU AI Act, said Parliament “has not been immune to AI slop and misleading AI-generated content,” and argued MEPs “must lead by example” as the Act’s own transparency rules come into force.
No disclosure required
Even after the hub launches, no rule will require an MEP to disclose when an amendment, question, or speech was drafted, in whole or in part, by AI. Staff face a stricter regime — internal guidance from April 2024, now under revision, requires labeling AI-assisted work and bars feeding sensitive material into public tools — but that obligation stops short of elected members. Some lawmakers have asked for formal guidance on the practice, and rewriting the rules may fall to Parliament’s constitutional affairs committee.
The hub’s reliance on US-based providers for its more capable tier also sits awkwardly next to the EU’s own sovereignty push, which has recently targeted American platforms directly over their grip on European markets.
