Mistral AI launches Forge, an enterprise model-training system

Introducing Forge

Mistral AI launched Forge, a system for enterprises to build frontier-class AI models on their own proprietary knowledge. It covers pre-training, post-training and reinforcement learning, supports dense and MoE architectures, and handles multimodal input. Models can be trained and governed on in-house infrastructure. Mistral AI has worked with ASML, Ericsson, the European Space Agency and Singapore's DSO National Laboratories to train models on their proprietary data.

Why it matters: It details the staged capabilities and named partners behind enterprise frontier-model training on private data.
