CEO of Mistral: Third party AI models are analyzing your company

Arthur Mensch, Co-Founder & CEO of Mistral AI, says that organizations using third-party proprietary AI models are opening up their business processes to their vendor. He claims that some AI labs have intentionally analyzed their most profitable customers’ data and behaved accordingly. “Frontier AI makes your business faster, but if you don’t control it, you won’t grow.” said Arthur Mensch.

To illustrate the power of specialized models, we can look at the case of investment company Bridgewater, where a model tuned on financial texts scored 84.7% compared to GPT’s 78.2% accuracy on domain-related tasks. Similar concerns regarding data sovereignty were expressed by Palantir CEO Alex Karp. Experts point out that Mistral’s statements also benefit its own business since it cannot match GPT-5.6 in terms of capabilities, but can in privacy and European data sovereignty.
