Mistral founder Arthur Mensch is making the case for open-source AI. In a LinkedIn post, he warns companies against depending on closed AI models.

Companies that sell closed models are storing more and more data, giving them a window into their customers' business processes, Mensch claims. Some AI labs "have a track record of going after their most successful customers thanks to this information," according to Mensch.

He advises companies to store their data in open systems, set their own access rules for AI, and build their own training models, even if "these efforts might seem daunting." "Frontier AI can accelerate the growth of your business, but if it's not in your hands, it's not going to be your growth," Mensch writes.

Mensch's comments follow similar remarks by Palantir CEO Alex Karp, who also urged companies to build their own AI models instead of relying on proprietary outside solutions. Palantir also published a manifesto for secure AI in business. Among other things, it reads, "Controlling your weights is controlling your fate. Weights are the distilled form of hard-won, accumulated institutional knowledge. If you let others control your weights, you are allowing them to migrate the alpha of your business to theirs."
