TL;DRMistral CEO Arthur Mensch used a LinkedIn post to argue enterprises must adopt open-source models, open data systems, and their own training flywheels, warning closed providers gain “immense leverage” over customers. His data retention and customer-competition claims have real but caveated anchors, and the argument doubles as a pitch for Mistral’s Studio and Forge products.
Arthur Mensch, cofounder and chief executive of French AI lab Mistral, has urged enterprise leaders to abandon closed AI models. In a LinkedIn post, he argued that closed providers are now forcing data retention and gaining “immense leverage” over their customers’ businesses.
As companies connect models to their internal context, Mensch wrote, providers see it, learn from it, and have a history of going after their most successful customers. The sharpest part of that charge, that providers use customer information to pick their targets, is an inference he offered no evidence for.
The data retention claim has a real anchor, with caveats. A US court ordered OpenAI to preserve ChatGPT logs during The New York Times copyright case, though enterprise and zero-data-retention API customers were excluded and the blanket order was later lifted.
