Mistral AI launched Forge, an enterprise model training platform that allows organizations to build, customize, and continuously improve AI models using their own proprietary data. The launch positions the French AI lab against hyperscale cloud providers in the enterprise AI infrastructure market.

The announcement follows an aggressive week for Mistral, which also released its Mistral Small 4 model, unveiled Leanstral — an open-source code agent for formal verification — and joined the newly formed Nvidia Nemotron Coalition as a co-developer.
