Mistral's own AI models will also be offered directly to Microsoft clients through its tools including AI assistant Copilot.

Microsoft on Tuesday sought to reassure European users with a "multi-billion-dollar" deal to rent AI infrastructure from Mistral, hoisting the French developer into the lucrative business of renting compute capacity.

Mistral's own AI models will also be offered directly to Microsoft clients through its tools including AI assistant Copilot.

The agreement "strengthens Europe's AI infrastructure while helping Microsoft meet growing demand for cloud and AI services" on the continent, the two companies said in a joint statement.

Neither company specified the exact dollar value of the deal or the amount of computing power Mistral would supply.
