Introducing Forge | Mistral AI

This post introduces Forge, a new system for enterprises to build custom AI models grounded in proprietary knowledge. It details the training methodologies supported (pre-training, post-training, reinforcement learning) and their application to enterprise-specific data like documentation, codebases, and operational records. The post emphasizes how custom models enhance enterprise agent reliability by providing deeper domain understanding, leading to more precise tool selection and reliable multi-step workflows. It also highlights support for dense and MoE architectures, multimodal inputs, and a continuous improvement lifecycle through RL and evaluation. The agent-first design philosophy is also mentioned, with Forge being usable by agents for hyperparameter tuning and synthetic data generation.
