100-word summary
Mistral AI launched Forge, a platform that lets organizations train AI models on internal data they don't want leaving their servers. Companies can now pre-train models on proprietary documents, then fine-tune them to follow internal rules (think compliance policies or approval workflows). ASML, Ericsson, and the European Space Agency are already using it. The catch? Only large companies with serious AI budgets and talent can likely afford it. But for regulated industries that can't risk feeding sensitive data to OpenAI or Anthropic, Forge offers something rare: a model that knows your business and stays on your infrastructure.
