France's government-backed 'Lucie' chatbot was pulled offline days after launch over nonsensical answers

French government / Linagora-led consortium·Lucie, a French-language AI chatbot backed by a French government AI initiative

Shortly after Lucie launched, users found it gave nonsensical answers to basic questions, including miscalculating simple arithmetic and, when asked about 'cow's eggs,' replying that they are edible eggs produced by cows.

Blast radius

The chatbot was taken offline days after its public launch amid widespread online ridicule; the developer consortium acknowledged it had been released prematurely.

Root cause

The model was released publicly while still, in the developer's own words, an early-stage research project rather than a validated production system

How it was caught

Users shared erroneous answers on social media within days of launch, driving public ridicule that forced a pause

What changed

Linagora said it would update the model, test a private beta, and relaunch only after further validation
