Introducing Forge

Mistral AI released Forge, letting enterprises train frontier-grade models on internal documents, codebases, and business data so models understand internal terminology, workflows, and compliance requirements. Forge supports pretraining, post-training, and reinforcement learning, works with dense and MoE architectures and multimodal inputs, and ships with data pipelines and Mistral AI's training methods, supporting continuous evaluation and iteration. ASML, Ericsson, and the European Space Agency, among others, have partnered with Mistral AI to train proprietary models.
