Mistral AI Launches Forge: Platform to Train Your Own Models Without Surrendering Data

Published on March 19, 2026 | Translated from Spanish

Mistral AI presents Forge, a platform aimed at businesses and public organizations. Its goal is to enable these organizations to train and manage their language models from scratch, maintaining absolute control over their data. It positions itself as an alternative to using external APIs, offering a complete internal and continuous development cycle.

A secure platform where businesses train AI models with their own data, within a shielded and controlled environment.

A complete cycle: from pre-training to specific alignment 🤖

Forge is not limited to fine-tuning. The platform covers the entire cycle: pre-training with proprietary data, post-training, and alignment through reinforcement learning (RLHF or RLAIF) to adapt the model to internal policies. It includes validated methodologies that Mistral uses internally, aiming to offer differentiated performance and total control over every stage of model development.

Goodbye to "what if the confidential prompt leaks to the API" 🔒

With Forge, the eternal fear that your most delicate query ends up in someone else's training dataset vanishes. Now you can make your own mistakes with your own models, in the privacy of your server. It's the solution for those who prefer their own team to program their corporate biases, without intermediaries. Data sovereignty never sounded so... autonomous.
